The fuel system is an important source to provide power for the car to run, a lot of cars with the failures are due to the fuel system is not working smooth, so how to maintain good vehicle maintenance in the fuel system is also an important part of, and in accordance with OBD diagnostic tool test results to distinguish fuel system maintenance methods will be slightly different. According to different engine fuel, the fuel system can be divided into gasoline and diesel vehicles, they should pay attention to what in the maintenance of the process?

Gasoline vehicle maintenance
Data show that: the 50% gasoline engine failure is caused by the fuel system, and the faults of fuel system and about 50% are caused by unclean because of fuel, therefore, How to remove the fuel oil in the water is an important part of the maintenance of diesel vehicles.

Gasoline will have some water, these are some of the extraction of water produced during some are generated due to external factors. At normal temperatures, the fuel may dissolve some moisture on their own, but in the winter the temperature decreases, the water solubility of the corresponding smaller, the excess amount of water will be dissolved together. The proportion of water is more than oil, it will slowly separated out, stay in the oil or filter the bend, causing the oil supply is not continuous. When the temperature is below the freezing point of water, the water will freeze coagulation, causing oil is not continuous.

In addition, gasoline, water will corrode and destroy the fuel supply system components. Therefore, we must timely use of Launch X-431 PAD and Launch X431 IV GX4 Master tool to effectively remove the fuel oil in the water, you can help the effectiveness of some detergents.

Diesel car maintenance
Diesel, for example, diesel fuel contains paraffin, which was dissolved at normal temperatures in diesel, and serves as lubricating oil and diesel fuel pump nozzle tip. In the winter, large temperature difference between morning and evening, and sometimes sudden cooling, paraffin will crystallization, thus crystals of various units together and form a "paraffin crystallization network" This network extends to all of the liquid, the complete control of diesel, resulting in Diesel loss of mobility, clogged filters, affecting the normal oil supply.

Once this phenomenon, the old traditional way is to spray the tank with water, you can make diesel fuel temperature, paraffin reintegration into diesel, but this method is not only time consuming, but can not completely dissolve paraffin diesel fuel, particularly paraffin oil pump and filter is inside. In this case, some people will be blended with gasoline or ethanol in diesel, used this method to solve the problem. But the engine oil system will cause a lot of negative effects. Such as excessive wear on the pump nozzle and fuel system components for corrosion.

The correct approach is actually very simple, as long as you join in gasoline or diesel fuel alcohol into a dedicated high-tech formula additives can, using Autel MaxiSys Pro MS908P and Autel MaxiSys Mini MS905 tools to detect. Meanwhile, in order to better conserve your car, maintenance of good fuel system, a method of maintenance of the regular cleaning is also very important.

After the new replacement parts, Toyota cars ignition key registration method:
1) After the engine ECU and the whole car lock core replacement, anti-theft alarm indication lamp flashes.

2) After the anti-theft alarm indication lamp flashes to confirm, insert a main ignition key (black) to the ignition switch.

3) About one second, burglar alarm light is off, the ignition key that registration is complete, then, You can also use the Launch X431 GDS and Launch X431 V+ Pro3 to check.

4) after the main ignition key registration is complete, burglar alarm indicator lights again.

5) anti-theft alarm status indicator lights after being confirmed, then pull out the ignition key. Insert two main ignition key (black) to the ignition switch.

6) About 1 seconds, burglar alarm light is off, the ignition key has been registered. After registration is complete, burglar alarm indicator lights again.

7) anti-theft alarm status indicator lights after being confirmed, then pull out the ignition key.

Insert the first three deputy ignition key (gray) to the ignition switch.

9) About 1 seconds, burglar alarm light is off, the ignition key has been registered.

10) After Unplug this ignition key, if burglar alarm LED flashes, which means that the registration is successful. If you want a quick registration, you can use the OBD diagnostic tool.

Note:
1) For the anti-theft ECU and engine ECU set as one unit (ECU), regardless of model, the ignition key of the registration of such methods are applicable.

2) registered ignition key sequence: the 1st main ignition key, the 2nd main ignition key, the 3rd Vice ignition key. If the ignition key to change the registration order, it can not properly registered.

3) If you do not make the correct registration method will cause the engine ECU recognizes only a handful of the ignition key, the ignition key into the ignition switch first one, so the other two could not start the engine, you need Autel MaxiSys MS908 and Autel MaxiDas DS708 diagnostic tool to repair cars.

In the long-term use of the car will be some glitches, especially tires, fuel, brake system is the most prone to security risks. How that happens should deal with it? If you use Auto diagnostic tools, it is easy to solve this problem without having to go to the repair shop testing.

Troubleshooting I: a puncture.
The tires are most likely to be worn and damaged areas. Especially when walking the mountain will always be stones or nails puncture the tire, many owners in order to save trouble, go to roadside repair shop repair about to continue on their way, and in fact, this method can only be a temporary remedy, when running at high speed will have the very big safe hidden danger. Recommendations the owner to find professional auto repair shop for repair in the repair shop, because the professional shop have car diagnostic tools, and repair will be more secure with special heating after vulcanizing machine.

Troubleshooting II: fuel consumption have increased significantly.
After a period of time in the car, many owners will find that fuel consumption increased by 10% between then more than this in the offing. In fact, the fuel consumption by up also indicates that there has been a potential failure of the vehicle. This is the first thing to understand the reasons for increased fuel consumption, you can use the Launch X431 V Pro and Launch X431 Diagun III tools to detect and then to be addressed. Factors leading to increased fuel consumption are many. For example, the clutch slip number of revolutions of the engine will be lost, resulting in increased fuel consumption, the need for timely replacement of the clutch pressure plate and drive wheels.

Troubleshooting III: brake failure.
Brake failure include: brake pedal stroke is too large, the braking action is slow, and even loss of braking efficiency is low, increase braking distance. In this regard, there are three troubleshooting methods. Continuous brake pedal, pedal gradually increased and flexible feel, but when you pause for a moment and then pedal is still low, there is air in the brake system, exhaust brake system response time. Foot brake is not working, but when the brake pedal several times in a row tread with good results, the brake pedal free travel is generally too large or brake gap is too large. Pedal free travel should be adjusted, and then check the brake clearance, if necessary brake repair disintegration.

For the car appeared glitches, the owner must not be ignored, it is a reminder of the existence of your vehicle invisible faults, timely resolution or use Autel Diagnostic Tool, not only to ensure traffic safety, but also to extend the life of the vehicle. So, please take it seriously.

FAW Volkswagen production Audi A6 sedan, airbags as standard. For the repair of the system failure, not only need OBD diagnostic tools, but also need to grasp the system composition, working principle and correct detection method.

Detection method and the matters needing attention in the process of maintenance
Airbag system installed on the Audi A6 sedan with a self-test function; every time the car will perform a self-test of the system; once the system detects a fault, the red light on the instrument AIR BAG will be president of the light. If the light is not on when you turn on the ignition switch, or in motion lights flashing, were indicative of a system failure, then the system needs to speak the line fault detection. Fault diagnosis of the system can only use special diagnostic VAG1551, VA G1552, V AS5051 or other Autel Diagnostic Tool and Launch Diagnostic Tool diagnosis.

Further, the system and other electronic control Audi vehicle systems, by using a dedicated diagnostic equipment, can be queried, part number and fault diagnosis system software version of its system, the implementation of the final element, clear fault code, and to read the data block The control unit encoding functions, the system address code is 15.

In the maintenance of the system needs attention to some of the following items.
1) prohibits the trigger line for testing, namely the driver and passenger side airbags, front and rear seat side airbags, and seatbelt tensioners trigger directly measure its resistance.

2) removable front driver and passenger side airbags, you must turn off the ignition, remove the negative battery cable. Driver's side airbag folded down, should be properly placed, prohibiting anti-put throw with touch.

3) airbag control unit must be replaced in the following cases: the driver or passenger side airbag is triggered after the first; front seat belt tensioner or side airbag is triggered three times; electrical lines under normal circumstances, Launch X-431 PAD and Launch X431 IV GX4 Master diagnostic system can not enter or fault code is displayed as 65535. In addition, the replacement of the control unit should be encoded.

No matter what the car is on the airbag, just as a safety auxiliary devices exist, can not use it as personal safety is guaranteed. Therefore, in daily driving, we should pay more attention to driving safety, be sure to use a seat belt device, or car diagnostic tools add a layer of security protection key.

Automotive air conditioning system is mainly based fluoride as the medium through the system pressure transformation, to reach refrigeration purposes. It consists of the evaporation tank, an expansion valve, a compressor, a blower, a condenser, a drying tank and lines. Evaporation tank is working in air conditioning systems work properly in cold environments encountered relatively hot outside air will produce water, which is in the evaporation tank structure, design outlet truth; wet environment evaporation tank and ventilation ducts and dust on the surface provides a breeding ground for mold and fungus favorable conditions for mold and fungus will soon multiply to mold and fungus group group of organisms that produce rotting smell that smell will open with the air conditioning, mixed in the air which, contaminate the entire car interior, occupants often make people feel uncomfortable, but also people have severe dizziness, chest tightness and discomfort. Early use of OBD diagnostic tool that can identify and solve such problems in advance.

Auto repair industry in order to solve this problem, is often demolished evaporation tank cleaning surface evaporation tank in order to achieve this approach fundamentally eliminate the odor, but every once demolished, they need to put fluoride, fluorine and other installation and processing a series of processes, cumbersome and technical difficulty, and low labor productivity. Because evaporation tank often work in a wet environment, and humid environment can easily produce mold, just to clear the air conditioning mold, over a period of time may have odors occur.

In addition, the automotive air conditioning systems as well as common problems and slight leakage of fluorine refrigerant adverse phenomenon, which also adds a lot more difficult to repair, Launch X431 V+ Pro3 and Launch X431 IV GX4 Master automotive tools can be easily resolved.

Automotive air conditioning system, air conditioning piping in power fluoro circulating from the compressor, the compressor lubrication oil is accomplished by fluorine. In the pipeline, together with the fluorine fluorine oil circulation to the entire system, which directly affect the flow of circulating air conditioning cooling performance, fluorine and fluorine oil for a long time at high temperature and high pressure and low temperature and pressure in the changing environment, coupled with the compressor work long hours under wear metal debris, etc., will produce gum and other deposits, some of these sediments are filtered out, part of the precipitation in each pipe, a small amount of the deposit does not affect the air conditioning cooling performance, but the deposition increasing material will affect the circulation flow rate of fluorine, which affects the air conditioning cooling performance. Air conditioning maintenance, we exclude the circuit, mechanical, pressure, temperature (including engine temperature) and fluorine and other reasons, the air conditioning refrigeration is still bad, we can use Autel MaxiSys MS908 and Autel MaxiSys Mini MS905 tool, the problem would be easily solved.

Battery plays an important role in the automobile use process, if it can not supply normal, car will not start running, while the car's power consumption in winter than in other seasons is much greater, and the battery is also afraid of low temperature, low temperature battery electrical capacitance is much lower than the normal temperature. So after entering the winter, special care for the battery is quite necessary, the battery life of about two years, if you use OBD Diagnostic Tool to check and timely care can prolong life.

First, external battery with a damp cloth to wipe it again, the panel, on the stigma (ie, both positive and negative poles) of dirt, oil, white powder and so easy to wipe clean the dirt caused by leakage and apply special grease to protect trailer coupling, to prevent corrosion.

The second step is to check the battery electrolyte leakage or deformation phenomenon. Some models are equipped with all maintenance-free battery, relevant or labels, do not disassemble the battery for this, if there is leakage, deformation of the phenomenon, it is best to go to the pits to solve. Maintenance-free battery life of about two years, expired on the use of Launch X431 Diagun III tool to check the battery voltage load voltage and starting performance, promptly replace if necessary.

The third step, if the car is parked in the open air or cold a few weeks do not, you should remove the batteries, stored in a warmer room, to prevent freezing damage to the rear battery self-discharge. When the ambient temperature is below minus 10 degrees, fully discharged battery will freeze, you must thaw the frozen processed before charging the battery, or directly charging may cause an explosion. If this happens, it is best to use a professional car repair small current slow charging stations.

So, in fact, battery maintenance is not difficult, you can try to use the owner Launch X431 GDS and Autel MaxiSys MS908 diagnostic tools, car to do maintenance on a regular basis, to extend its working life.

Speaker is a device frequently used while driving, like OBD Diagnostic Tool for the mechanic is the same, if the speaker appear problem, it will be very convenient when driving. Sometimes honked the horn, very hoarse, and even a little voice at all. what causes it?

Let's take a look at how the horn works. When you press the horn button on the steering wheel or other locations, the current from the battery flows through the loop on the horn relay solenoid, solenoid relay attract dynamic contact switch is closed, current will flow to the speaker place. Electromagnet current work inside the horn, so that the diaphragm vibration sound. If the problem is not very serious, the owner can solve their own, Launch X-431 PAD and Launch X431 Diagun III Auto Diagnostic tool can check and fix this problem.
solve the problem of automobile horn

The failure in many of the speakers, especially some design defects speaker mounting location, in the rain, very easy to cause the horn drenched by rain, causing damage to the speaker. When the speaker does not ring, common failure parts have no more than 3 points, namely the horn itself, horn switch contacts and the horn wiring harness, when fault occurs can refer to the following steps to check, of course, you also need some car diagnostic tools.

(1) Sometimes does not ring, press the horn switch, if the speaker sometimes loud, sometimes not loud, mostly horn switch contacts inside the contact is not good, and some are also speaker itself.

(2) hoarseness is due to poor contact plugs, especially the various contacts around the steering wheel, as a result of frequent use, easy to make contacts to wear.

(3) does not ring entirely first checks to see if the fuse is blown, then unplug the speaker plug, use a multimeter to measure when the horn switch here has power. If there is no power, check the horn and horn relay harness; if there is electricity, it is the speaker itself is the problem, then you can try to adjust the adjusting nut on the horn to see if sound, or you can use Autel MaxiSys Pro MS908P or Autel MaxiSys MS908 auto tool, if still does not ring, you need to replace the speaker.

Among all the car maintenance, the battery maintenance is also very important. While many car owners do not pay enough attention and have not a better knowledge of both the using and the maintenance of the car battery. As a result, they have not formed a good using habit and make the battery life shortened, and even do harm to the other electrical equipment. So, how to check whether the battery can still support working with your car? Maybe you can use a car diagnostic tool for help. A common battery life can be up to 2 or 3 years, if unreasonable used, you may change the battery of your car within 4 months.

Well, how to judge whether the battery need charged, and not make it in a state of loss of electricity? You can determine the working state of the battery by the brightness of the headlights or the strength of the stereo sound. If you wait until the brightness of the light become dark, the power storage would have entered into a state of loss of electricity and unable to start. In order to guarantee the normal work of the battery car owners should better start the engine to recharge it for every half an hour after the using of the battery.

Here are four errors for the using of the battery. All should pay attention:
1. Not charged with the new battery for the first use
Battery charged at the first time is called the first charge, which has a big influence for the battery life of your car. If not charged, and used directly, the capacity if the battery will be not large enough and shorten the battery life. While if charged directly, it will also shorten the battery life. In general, the first charging of the battery is after filling the electrolyte, and use a small current to charge it for about one hour and then you can use it.

2. Ignore the vent of battery
The vent of the new battery cover is usually sealing, when using you must first remove the adhesive paper, otherwise the air vent cannot be ruled out the gas during the chemical reactions, and will lead to an explosion because of the high pressure.

3. Too freely to add distilled water for the battery
Usually after adding the water for the accumulator, you must let the car run for a period of time, and charge the battery through the generator, making the distilled water and electrolyte fully mixed, and then the battery performance will not be affected. Well, after a long time of driving, we suggest you to use a king of tool to make a full checking for your car, including the battery life, such as the Autel MaxiSys Pro MS908P and Launch X431 IV GX4 Master Auto Diagnostic Tool, both are the best choice for you. Conversely, if not running after adding distilled water, distilled water and electrolyte will not be fully mixed, and it can cause the battery self-discharged or damage battery polarity.

4. Battery charge capacity not matched with the engine
If the charge capacity and engine don't match, battery charge quantity is small, the startup resistance increase, battery will put severe electricity, and is sure to shorten the battery life. If charging a small car with large capacity, the active substance will not be fully used, as a result, it will lead to a decline in economy. When loading, the battery is based on the starter battery power, voltage and the load of electrical equipment, so in exchange, it is important to note that matching the engine charge capacity.

Well, for more detailed information about the car maintenance please continue to pay attention to our Auto Diagnostic Tool Online Store and we will upload the latest and most practical knowledge for maintaining your loved car for you.

Just using and never think of the maintaining methods, after a long time, it is sure to lead to problems with the air conditioning of your loved car. Maybe you are still not sure whether your car air conditioning can work well or has been damaged by improper use, and then you should have it fully checked with a kind of OBD Diagnostic Tool for diagnosis. Well, what problems will usually appear on the car air conditioning?

1. Clean water tank and condenser
Water tank and condenser are the important parts of the vehicle cooling system and air conditioning. With the long time of using, dust, sand and catkin will be mixed in the gap between the two, as a result, it will influence the water temperature and the performance of air conditioning refrigeration.

2. Check the air pressure and change refrigerant
First, check it is the high pressure test tube or low pressure test tube, and connected with the fluoride pressure test table, after that, start your car with a lower speed. And then turn on the air conditioning switch, and turn it up to the maximum for checking, the checking result should not be more than 300 under the idling situation and no less than 60.

3. How to choose the best oil viscosity in summer?
Many car owners may complain about using more oil. In fact, in summer, they can choose the low viscosity lubricating oil in the summer, of course, which can be just used under the situation of good shape, smaller wear. While for the cars that have run too long, and with an older age, it is better to use the lubricating oil with bigger viscosity.

4. How to clean the air flue and replace filter?
The original filter life of the automobile is 12000 kilometers once a time under normal use. It is very simple to clean the air flue of the car. Block the air outlet up with wet towel, and adjust the speed to the maximum, thus the dust will be absorbed on the towel. In addition, you can also use the air conditioning duct cleaning agent, added with the high pressure air gun and clean it for two or three times so that you can gain the purpose of cleaning. As we know, good filter is sure to be very important for the normal operation of your car. Here we suggest you to go to an online car diagnostic tool shop for help, and choosing the best tools for checking, such as Autel MaxiDas DS708, Launch X431 Diagun III, Launch X-431 PAD Auto Diagnostic Tool, etc

5. How to get rid of the musty of the air conditioning?
Some car owners may find that there will be a smell of musty on the air outlet when turning on the air conditioning, this is because you have not cleaned up the air flue in time. The most simple method to solve it is to clean the air flue, also you can make it with the help of the air conditioning duct cleaning agent. Moreover, after using the air conditioning, you should not shut in down immediately, instead, keeping the air switch on about 5 minutes.

Besides, you should also pay more attention to the use of the circulatory system both inside or outside the car during hot summer. Lots of cars use the manual air conditioning, when adopting the outside loop, wind will be entered into the car conditioning from the outside of the car, while the inner cir

Airbags, as the name suggests is to protect drivers and passengers safe, safe driving, the airbag will not play a role, especially in the frontal crash once an emergency occurs, it will play a role to ensure the safety of your life. Therefore, understanding and careful maintenance of the car's airbags is one thing you can not be ignored.

First, the airbag is a disposable product. After the collision detonated, the airbag will no longer have the ability to protect, and to be sent back to repair factory to replace a new airbag. Due to the different models, the price is not the same as the airbag. Re-installation of a new airbag system includes sensors and computer controller, generally need about 5,000 yuan to 10,000 yuan.

Second, do not balloon in front of, above or near the place items. Because the balloon will explode in an emergency situation, so do not balloon in front of, above or near the place items to prevent detonation was hurt when the airbag occupant ejections out. In addition, the installation CD, radio and other accessories in the room, to comply with the manufacturer's requirements, not free to modify parts and lines fall within the scope of the airbag system, so as not to affect the normal operation of the airbag

Third, children have to pay attention when using airbags. At present, many airbags are designed for adults, including the airbag in the car's location, height. Balloon inflated, it may cause harm to the child in the front row. Suggested that children placed in the rear center position and secure.

Fourth, pay attention to the daily maintenance of the airbag. Mounted on the dashboard of the vehicle when the airbag indicator light, under normal circumstances, the ignition switch to the ACC position or the ON position, the warning light will shine about forty-five seconds to self-check, then turns off. If the warning light stays on, it means that the airbag system failure, you should immediately repair the airbag malfunction or misuse of the situation in order to avoid the emergence of pop.

Some OBD diagnostic tools will help you test out your vehicle on your own, for example: Launch X431 GDS, Launch X431 Diagun III, Launch X-431 PAD, Autel MaxiSys MS908 and so on.

Engine wear will affect its normal operation, the heavy will cause the engine to a shorter life. So, on the vehicle maintenance, wear control is essential to take appropriate means of automobile engine. So to reduce engine wear, need which the check engine?

High quality oil
The engine is running, the internal metal surface of the cylinder at high speeds of several hundred degrees Celsius environment, mutual friction, inevitably leading to wear of the engine; especially for a long continuous operation and the load and heavy trucks, may produce wear sex even higher. High-quality oil can effectively control engine wear, not only that, it can effectively suppress the generation of carbon and sludge, thereby controlling impurities within the oil channel surface wear and tear on the engine.

Ensure that the water, oil in the normal state
Want to make a smaller engine wear, the need to always concerned about the state of the water / oil dashboard. In general, the water temperature should be controlled at about 80 degrees Celsius is appropriate, and the oil pressure gauge is displayed as 1 kg if traveling in the slow, shown as 4-5 pounds of oil pressure is normal Express travel. If some vehicles with engine oil pressure light, respect and pay attention to the oil pressure light is illuminated, lit it indicates that the state is not normal, the driver will need to attract attention, car maintenance should be carried out immediately.

Develop good driving habits
Poor driving habits of engine damage is very large, to control the speed while driving, proper coordination of engine speed and gear control, avoid low-speed, high-grade low speed. In addition, the vehicle should be kept constant speed, driving the process to avoid Bigfoot throttle, brakes Bigfoot, not to change lanes frequently. Usually for a truck to run high-speed road, the 80 km / h is more fuel-efficient, safe speed.

Some Auto diagnostic tools will help you test out your vehicle on your own, for example: Launch X-431 PADII, Launch X431 IV, Launch X431 Pro3, Autel MaxiScan JP701 and so on.

In the use of the car, often leak failure occurs, it will directly affect the technical performance of the car, leading to oil, fuel waste, power consumption, the impact of the car clean and tidy, causing environmental pollution. Because oil spills, reduce internal engine oil, resulting in poor mechanical lubrication, insufficient cooling, can cause mechanical damage early, even leaving accidents.

First, The common main reason for the vehicle oil spill

1, the product (accessories) quality, material or workmanship is poor; structural design problems.

2, improper assembly of high speed, with the dirty surface, liner damage, displacement or failure to standardize procedures for installation.

3, tighten the nut force uneven, slippery silk buckle or break off as a result of work Songkuang failure.

4, after long-term use of the sealing material wear off limits, aging metamorphism, deformation failure.

5, lubricants add too much oil too high or mistake of oil.

6, parts (side cover type, thin-walled parts) engagement surface deflection, the housing is damaged, so that oil leakage.

7, vent plug, after the check valve plug, due to the pressure difference inside and outside the enclosure role, often lead to seal leakage weaknesses.

Second, Oil spill prevention measures of vehicle

1, emphasis on cushioning effect. Automotive standing parts (such as the end face of each engagement, each cover, shell, cover mats, flat enamel cover, etc.) gasket leak-proof seal between components plays a role. If the materials, production quality and installation does not meet the technical specifications, leak-proof seal would not achieve the role, and even accidents. Such as the oil pan or valve cover, due to the large contact area and difficult to compaction, the resulting oil spill. Note that when handling properly placed, carefully check the press specification assembly.

2, various types of fastening nut torque the car are tightening regulations required. Too loose, not tight pressure pads would leak; they will screw around tight metal bumps or threaded twist slip caused oil spills. In addition, the oil pan drain plug back if not tighten or loosen off, likely to cause oil loss, and subsequent "bush-burning axle" of engine damage accident.

3, the timely replacement of seal failure. Many parts of the car moving home (such as oil seals, O-rings) due to improper installation, journal and seal edge misalignment, yaw and dumped oil. Some seals used for a long time due to rubber aging and loss of elasticity of the canal. Found leakage should be updated.

4, auto parts used for a long time will produce excessive wear limit (eg, such as piston and cylinder), resulting in the combustion chamber of high pressure gas into the crankcase, and forcing the oil leakage. Therefore, when added to the oil filler cap emissions at channeling serious, should try to repair or replace worn parts.

5, to avoid a one-way valve, vent valve blocked. The resulting temperature rise within the housing, oil filled the entire space, not the canal discharge, increased pressure within the housing so that oil consumption growth and replacement cycles. After the engine ventilation system is blocked, increasing the resistance movement of the piston, so that the fuel consumption increases. Due to the pressure difference inside and outside the enclosure role, often lead to seal leakage weaknesses. Hence the need for regular inspection of the vehicle, and clear, clean.

6, various types of pipe joints sealed properly addressed. Car union nut often removable, easy to slip off the buckle and loose wires; two joint bell poor accuracy, the two do not coincide with the center line of the cone and the bad; not coincide different taper, which will cause oil leakage . Replace the union nut with grinding solve its cone seal, compression nut and resolve seal.

7, to avoid rejection oil hub. Wheel bearings and grease cavity excessive or improper seal assembly, poor quality and aging failure; wheel brake frequently caused by high temperatures; axle nut loose, and this will lead to rejection of the oil hub. So useful "cavity lubrication" vent clear, strict selection of high-quality accessories, according to the high-speed assembly and process specifications.

Third, the maintenance and overhaul of the main points of the vehicle

In extremely clean conditions for assembly, parts work surface no bump, no scratches, burrs and other fixtures; strict rules, seals should be properly installed, do not be put in place to prevent deformation; grasp performance specifications and requirements of the seal timely replacement of failed parts; side cover classes for thin-walled parts, the use of sheet metal cold do correction; easy to wear shaft hole type parts can be metallized, repair welding, gluing, machining and other processes in order to achieve the original size; try using a sealant, if necessary, can paint to achieve the desired sealing effect of alternative; slide wire nut off button, release should be repaired or replaced with new parts, and tighten to the specified torque; should be carefully examined before the appearance of quality rubber seal assembly; use press with specialized tools, to avoid distortion beat; filling grease required regular cleaning to clear the vent and check valves. Just do the above, the vehicle is completely leak problems cure.

Many car owners often neglect cleaning and maintenance. Very easy to breed bacteria, and finally endanger the driver's health. Therefore, even if the car no matter how busy have to remember to do some cleaning and disinfection.

The main methods of disinfection automotive chemical disinfection, photocatalytic disinfection, ozone disinfection and sterilization of activated carbon in four ways. What are the specific advantages of disadvantages of the four methods, as follows:

Chemical disinfection:
The so-called chemical disinfection is to use some disinfectant to wipe the interior of the car, especially in parts of the door handles and other frequently touched, can reach a certain disinfection. The most commonly used disinfectant on the market as peracetic acid, Lysol disinfectant and 84.

Disadvantages: easy to leave chemical residues, causing potential harm, while auto parts also have a certain degree of damage. Chemical disinfectant and bleaching are generally corrosive nature, need to be careful and metal automotive interior parts use.

Photocatalytic disinfection:
Photocatalyst disinfection is the use of the photocatalyst coating film and the chemical reaction sunlight, then the car quickly decompose harmful substances harmless stable material, in order to purify the air function. Advantages photocatalytic disinfection sterilization effect is good, keep a long time.

Disadvantages: photocatalytic disinfection drawback is that it only under ultraviolet light to produce an effect, and ultraviolet radiation on the human body has some damage. In addition, during the operation photocatalytic disinfection of complex, demanding professional operators.

Ozone disinfection:
Ozone disinfection disinfection belong to the car with the air conditioning circulatory system approach, the use of special disinfectant into the circulatory system, may be the car to remove the odor, there are certain disinfection sterilization effect, especially for amines, nicotine, bacteria and so on. Ozone disinfection operation is relatively simple, the hose is connected to a vehicle for disinfection extends into the compartment, open vehicle for disinfection, disinfection to each corner of the car to discharge high concentrations of ozone generated by the high pressure, so just a few minutes on it.

Disadvantages: If prolonged use of ozone disinfection will make the car rubber aging. And ozone quality car decoration beauty shop in different ways, each time the price level disinfection range. And each will leave little odor.

Activated carbon disinfection:
Activated carbon for car owners is the most effective, safest, and most likely way to achieve. Since activated carbon has pores and more features, formaldehyde and other harmful substances with strong adsorption and activated carbon are physical methods, does not produce secondary pollution.

Disadvantages: slow virus, is not complete.

Some auto diagnostic tools will help you test out your vehicle on your own, for example: Launch X431 IV, Launch X431 V Pro, Launch X431 Pro3, Autel MaxiSys MS908 and so on.

1. Tie a hole
For a long time already make tires, even temporarily, no problem with them, but at the limit of endurance will load than ever before; in addition, on the same tire if you have three or more tie a hole, we still We recommend that you replace it as soon as possible.

2. Drum package
If the high-speed passing car pits, obstacles and curbs midnight, local tire will deform under severe huge impact force, thereby increasing the internal pressure moment, this is a direct consequence of causing cord sidewall bulge caused by rupture . Also in the same impact strength, high and low profile tires flat tire more easily than cause sidewall bulge. Drum kit has happened tires must be replaced immediately, otherwise there is a puncture hazard.

3. Texture
In general, a normal family car can use every 60,000 km or two years to replace a tire, but for serious tire tread wear should be early replacement. Now fast repair shops have tread wear ruler, the owner can buy a ready test their tire tread wear. In addition, increased tread crack is serious aging symbol can usually appropriate protective wax spray some tires, there is pressure to try not corrosive liquid while driving.

4. Pressure
Most cars are now home use tubeless radial tires for the front-drive for the engine, transmission and other important drive components are pressed at the front, so the front sometimes look a little deflated, but the visual is not accurate and must use special air gauge measurements. Generally the front air pressure between 2.0 -2.2 Pago Pago, (due to the use and design of each vehicle are different, so it is best to use a reference manual on the factory calibration value), the summer can be appropriately lower.

5. Stones
Some owners will often hear when driving their car will be issued a "flap" sound, but the car but there is no fault with it, then you must check is not a pebble stuck in the tire tread in the. In fact, as long as usual taking the time to tread the lines with the key in these stone tablets dug up, the tires will not only be more stable braking grip, but also to avoid the tire noise.

6. Spare tire
To spare to play a real role in the emergency, usually must pay attention to its maintenance. First, we must always check the spare tire pressure; secondly, to pay attention to oil spare eclipse, spare tire rubber products, various oil fear erosion. Rear tire contaminated with oil, inflation will soon eclipse occurs, it will greatly reduce the life of the spare tire. Finally, the spare tire around the life of four years, many owners mistakenly believe that it has no spare tire is new, in fact, even after 4 years and never once used the spare tire should be replaced, otherwise it becomes scrap spare tire .

Some OBD diagnostic tools will help you test out your vehicle on your own, for example: Launch X-431 PAD, Launch X-431 PADII, Launch X431 Diagun III, Autel MaxiSys Pro MS908P and so on.

Check the car before departure
First check wiper. The best is to put every gear wiper try them and see if it is working properly; Also, pay attention to the wiper blade wiper usually used in negative net, if not clean, then we must be replaced. If the wiper failure because of driving rain, it is prone to accidents.

Moreover, the kind of severe tire wear is hidden driving rain, so the tires before driving to note whether there is normal wear and tear.

How to remove the mist produced by the process of moving the car windshield?
The most common method is to turn on the air. This is because the cool air is blown onto the glass, a "cold film" is formed on the surface of the glass to prevent carbon dioxide condensed on the glass, play a defogging effect. You can also buy the auto parts store or fogging dehazers towels. Defogging agent is sprayed onto the glass surface within an automobile, and wipe clean, clear glass in the dirt while also forming a thin transparent protective film on a glass, to prevent the water vapor mist is formed on the glass layer condensation.

What to pay attention to when it rains stop?
First of all, do not stop the rain, air conditioning. In rainy days, when the low-speed parking, gasoline by water vapor, temperature, engine speed and other effects are not able to fully burn. When the car is stopped but the air conditioning did remain open, but the car is still in the closed state of the doors and windows, interior air convection can not, if the engine exhaust carbon monoxide leaking into the car, and it will gradually build up concentration, leading to poisoning and even death of adverse consequences. Secondly, do not stop at stop unsafe in high winds, heavy rain location trees, billboards, telephone poles, walls, etc. Do not stop at the low-lying area, such as tunnel hole, pothole zone, downhill, under the overpass, etc., so the car was flooded.

After driving the car in the rain should be how to care?
First, the car dehumidification. Should open the cold when it rains, it can not only remove the mist, as well as dehumidification function. The rain stopped even have to pay attention, to get rid of as soon as possible the accumulation of moisture, or prone to mildew and other conditions.

Second, the car sterilization. Rain as temperatures and other factors, relatively easy to breed a variety of bacteria, so the interior space disinfection sterilization is particularly important. Focus on clean corners everywhere.

Third, the conservation of the chassis. Owners can conduct a "sealed plastic chassis", which enables chassis and isolated, to corrosion, rust, noise function, can effectively extend the life of the body.

Fourth, check the brake. Because of the braking system has a very strong adhesive force, rain is very easy to enter the brake fluid, it will affect the braking effect, may cause serious Zhidongshiling. For the treatment of this condition, the rain to a professional auto repair shop on the brake system checked.

Some auto diagnostic tools will help you test out your vehicle on your own, for example: Launch X431 IV, Launch X431 Pro3, Autel MaxiSys MS908, Autel MaxiDas DS708 and so on.

Predict the primary road lights
To be able to increase road capacity, the town has generated many of the primary streets from the road. In visiting the primary streets in to the evening, while exports to look at if the lights and also at the entrances. Since the transport sector designed inlet and outlet direction using the almighty, there's a particular streets direction position, normal automobiles can’t direct the sunshine only into and from the primary, side streets can direct light automobiles found in other automobiles.

No fence reduce speed
Many mixed lane no center guardrail, the situation for that vehicle while browsing line once the side lane unimpeded, are available around the vehicle lights are uniform and regular. At this time, carry the type of people on the streets crossing the street, the motive force is frequently because of the sunlight from the vehicle blind spots. Motorists should give consideration to decelerate with the instructions prior to the vehicle was moving with the front from the vehicle once the lights change.

Shadow flicker watch out for people on the streets
If there's a shadow flashing lights, showing that there's a pedestrian before their vehicle or cyclist, and also the distance between your intersections continues to be close. To avoid sudden deceleration people on the streets must advance, don't leave items to chance to be able to avoid accidents.

Fluctuations uneven pavement lights
Additionally, with the oncoming vehicle lights to look for the road ahead fluctuations flatness, you may also make use of the vehicle tail lights observed prior to the discovery from the vehicle car headlights reflecting if the defect.

Effective utilization of the lights of other automobiles driving at night, you are able to enhance the driver's capability to judge, to prevent traffic accidents.

Front lights on first in alley
Toward the spacious urban streets, in addition to a narrow alley and mix the intersection, automobiles or people on the streets frequently all of a sudden come out of the alley, when the driver doesn't take measures to identify danger prone. When we can watch within the mouth drawn from the vehicle lighting can avoid accidents.

In the event that there's direct light from the alley, showing the automobiles drawn out of the mouth sized based on the brightness of lights and lighting can determine the peak of the vehicle: vibrant lights, everywhere for that vehicle, the lights dim, and our prime position of huge cars. Then your driver should decelerate, whistle, used interchangeably far and near lighting help remind one another.

Automobile steering system common fault is mainly: the steering wheel rotation is too large and manipulation of the instability, the front wheel, steering the heavy head, wandering. Steering wheel transport is too large, unstable manipulation check steering pump ball head, the place such as the king pin and bushing, wheel bearing wear, such as severely worn or clearance overrun. Repair should be adjusted. If no excessive wear or clearance, you should check: first, the abrasion of steering worm gear and worm, or clearance is in accordance with the provisions, such as the large clearance should be adjusted; Second, wear parts of the steering device together, or whether to adjust too loose; Third, the redirect or installation parts loose; Fourth, the steering arm loose.

When the car running deviation, can check the following: whether the tire pressure is equal to or tire diameter are equal; Whether the wheel bearing side too tight; On both sides of the spring steel plate is uneven stretch or deformation; Before the beam is correct, camber Angle are equal; Steering knuckle arm, steering knuckle for bending or deformation; Rear axle shaft for bending tube; Wheel base on both sides are equal.

Check the wheel dynamic balancing. Tire assembly is correct, check whether the tire wear uniform, check the balance block assembly is correct. Check the wheel rim for deformation; The deflection of wheels for lateral or radial swing; Shock absorber for loose or wear; Steering linkage section, horizontal, straight or redirect or assembly for loose; Spring steel, U bolt clamping bolt for loose or damage; The Angle is correct; Tire pressure is correct. Except by high-speed put head to check the contents of the project, especially emphasize the check to the top of the following: tire pressure is correct; Steering knuckle bearing ever loose; To horizontal, straight linkage section ever loose; If there's any loose for steering gear assembly; Spring steel, U bolt clamping bolt for loose or damage; Spring plate whether residual deformation.

About maintenance the car is the best way is often checked the car; you will find problems early and avoid unnecessary losses. Here we recommend some car diagnostic tools can help you test your car by yourself, such as: Launch X431 IV, Launch X-431 PAD, Launch X431 Pro3, Autel MaxiSys MS908, Launch X-431 PADII and so on.

Condition 1: driving sideslip
Rainy days is slippery, the possibility of sideslip increase in traffic, in addition to good driving habits and skills, good brake with the state of the tire was the key to safe driving. The vast majority of car braking system is dual-pipes hydraulic braking vacuum booster. The brake fluid from transfer braking is extremely strong water imbibitions. If there is water into the brake fluid, in the process of braking, the high temperature of friction produces water vapor. And gas compressibility in the brake fluid is compressed, can cause brake failure and even failure.

The solution: some serious vehicle brake fluid bibulous, in the brake fluid oil droplets can be seen on the lid. So have to check the brake fluid during maintenance, to ensure driving safety. Once found the car brake fluid bibulous serious, should send professional repair shop in addition to the water.

In addition, before the rainy season if it is found that vehicle tire wear, loss of tire, and must be replaced. Someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important.

Condition 2: wiper failure
If you often drive a car in the heavy rain, the line of sight is not clear is the biggest hidden danger, the importance of wipers are evident. And at this point, if the wiper conditions such as vibration or have different ring, that you be careful, because it is likely to be in it to send warning to you.

Solution: increasing the monsoon rain must let the wipers to assume more responsibility, for wiper inspection and maintenance to be more careful. Because rainy days the road and the line of sight of them are good for driving, if the wiper cannot very good brush away the rain, it will be great danger to traffic, the wiper plays an important role, so more careful inspection and maintenance of it in place.

Owners themselves put wiper switch speed of various location, pay attention to the wiper is there a vibration at work or have different ring, check whether the wipers under different speed to keep a certain velocity, the status of the wiper and wiper strut uneven whether there is a swing or leakage phenomenon. Both fault in any kind of means that the wiper blade damage. At this time can be used, with finger touch on rubber wiper blades, check for damage and elasticity. If the crack of leaf aging, hardening, or, should be timely replacement. Replacement blades work is not complicated, can do it yourself. Remember to first figure out what kind of specifications of the car wiper blade.

Condition 3: rainy day engine start
In the rainy season is the most critical for cars "heart" - the engine maintenance. The owner on a rainy day when the engine is not easy to start with, sometimes even forced up, is also a whisper.

Solution: this problem from the ignition system is the biggest reason due to damp the leakage. Once found because of ignition system of the wet and cause adverse, engine ignition performance, can temporarily use dry paper towel or dry cloth to dry distribution plate and wire inside and outside, if because of aging leakage must be replaced immediately.

Rainy days also often wade, after wading car performance due to several water fell, serious can lead to the car can't run normally. This of course, also is most likely from the ignition system leakage caused by moisture. Because rain is the best conductor, turbid in electricity after water is likely to cause a short circuit.

If the move engine stalling doesn’t repeatedly ignition start-up, should wait for a period of time or checking circuit, otherwise extremely easy to cause the engine scrap. When the car should be timely after smooth wading through the circuit equipment for maintenance, can with a paper towel or dry cloth dry circuit one by one to start again.

Here we recommend some OBD diagnostic tools can help you test your car by yourself, such as: Launch X431 V Pro, Launch X431 Diagun III, Launch X431 GDS, Autel MaxiDas DS708 and so on.

Prevention tire: tire pressure down promptly repair
The hot summer is high season car tire. Due to the high temperatures, low quality or if the tire itself tire pressure is too high, the tire after gas expansion will lead to a puncture. Therefore, we recommend that owners will be tire reduced by 10%, adjusted to 2.2 kpa.

Owners should pay more attention this season on tire maintenance, if damage is discovered, it should be promptly repaired or replaced. If you have patched the tire, it is best to put the rear wheels or as a spare tire. In addition, particular attention not to let the summer tires collision obstacle, because it is easy to make the tire sidewall injuries caused problems.

Reminder: If the tire which occurs in the driving, the driver applied the hand tightly control the steering wheel, slow step on the brake, the vehicle smooth deceleration stop. Do not be an emergency brake, because it is easy to cause the flick even rollover.

Water temperature exceeded: Timely parking thermal cooling
Summer car drivers who not only baked, vehicles will be unable to withstand high temperatures, excessive water temperature is relatively common, even "boil" boiling. Summer car owners should always pay attention to see when the water table, look at whether the water tank.

Driving, if you find the water table pointer nearing the red line, it should reduce the speed as soon as the car drove into a cool place to stop. To avoid engine damage, do not immediately turn off after stopping, but should let the engine idle for a period of time before.

If the water temperature is still not fall down, you should turn off the car, check the engine coolant. But be careful not to open the radiator cap immediately, otherwise it is easy to steam burns. If it is because of lack of coolant, it would first make up.

Reminder: If the water temperature is too high the phenomenon, do not let the car on long journeys, because for a long time with a lot of damage to the engine water temperature is not under normal circumstances; do not slow down especially not choose congested roads.

Auto ignition: Reducing modified periodically check
Prevent the car ignition; the most basic method is to periodically do maintenance to the car, check the engine, and an oil circuit, to see whether the aging and oil spills. Do not store in a non-standard vehicle repair or modification, because of some wrong operation of Luanda wires, easy to friction is not effective at a fixed, will be dangerous.

If the modified car, especially lights, sound, etc., should be comprehensive examination. In the hot summer, do not lighters, fragrances, air fresheners and other flammable items placed under prolonged exposure to high temperatures inside the car to avoid swelling caused by physical explosion sparking spontaneous combustion; After a long journey, it should be appropriate to let the car rest what to avoid overload.

When driving, vehicle owners should be aware of signs of spontaneous combustion, such as an odor, abnormal sound or vehicle electrical malfunction and so on.

Reminder: The best car standing on a fire extinguisher. Once spontaneous combustion, the first car in the right place few people pull over, turn off the heat, remove the fire extinguisher, look for fire points to the part of the cooling tank and burning fire to avoid explosion.

Here we recommend some OBD diagnostic tools can help you test your car by yourself, such as: Launch X431 Diagun III, Launch X431 Pro3, Launch X431 IV, Autel MaxiDas DS708 and so on.
