The most common fault of the automotive cooling system is making the car broken down, and the loss of water., With the loss of water as well as accelerating weakness fault. Checking the vehicles with the boil water tank, first you should to use the OBD Diagnostic tools to detect other related components properly, such as using the correct grade of fuel, oil, spark plugs, antifreeze and adjust ignition timing and idle air-fuel ratio. And further check the cooling system under the normal circumstances.

Daily checking for the cooling system
First look at the water tank. Under normal circumstances, the tank will keep a consistent temperature when driving, if half cold or hot situation appears, you can determine the tank internal was blocked. You can connect the tank to the two kilograms of water pressure, reverse flush, if congested, you can use small amount of cleaning agent, taking care to clean the dirt tank and observe for leaks at the same time.

Second, look at the thermostat. Some people think that the removal of the thermostat can prevent the water temperature up to high, in fact, as long as the thermostat function properly and does not cause the water temperature too high, while the engine is running at low temperatures for a long time, it will be very harmful. In addition, many additional engine thermostat is a two-way action, when the thermostat is turned off, it will force to go small circulation of cooling water, while the thermostat is turned on, small loop will be closed, the cooling water will take the big loop at a whole. If you do not install the thermostat, because of the local resistance line throttling effect, the actual flow of a cycle is with very little water, but the water temperature rises.

Finally, using the Launch X431 GDS OR Launch X431 V Pro tool to check the pump. There are three ways for the damage of the pump: leakage, turn and throw impeller corrosion. The so-called revolution is lost pump shaft and impeller with too large gap, when the engine reaches a certain speed, the pump impeller can not reach the appropriate speed, resulting in poor water circulation. Cooling fan is the main component, and some cars have been eliminated fixed fan, and replaced with silicone oil electromagnetic and fan clutch. The characteristic is it basically does not work by a cold car fan, and the maximum amount of heat hot car; silicone fan clutch main fault is that oil spills, and the main fault of electromagnetic fan clutch is damaged water temperature switch, damaged line, and the damaged electromagnetic coil.

Cooling System Maintenance
1. Use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool check the cooling system seal, tightness of the fan belt, thermostat sensitivity and cooling water temperature, and keep plenty of cooling water.

2. Cleaning the cooling system, including the heat sink, the water jacket adhesion of scale, in order to prevent fouling in the cooling system thermal performance.

In many people think maintenance is to replace the three filters, oil and other consumables. In fact, during operation of the vehicle, many parts are constantly wear, routine maintenance, inspection range well beyond the three filters, oil, brake pads, spark plugs, a lot of places if you usually do not use Auto Diagnostic Tool inspection, maintenance, maybe there will be a failure. Here is a little common sense of car maintenance in the summer.

1, air conditioning use
Open air conditioning cycle. In the summer, the temperature is often high, so that the car is just starting to open the air conditioning, it should open all the windows 3-5 minutes, until hot and then drain off the air conditioning, it would play better results. If the engine is in a large load for a long time, it should temporarily turn off air conditioning. Refrigeration and air conditioning when the wind blows up the best, because the cold air to sink, the best choice for the wind blowing side gear block, adjust the air outlet up best. Finally, noting that the former first destination off the air conditioner to reduce odor generation.

2, body care
More rain in summer and autumn, rain acid rain, as well as strong sunlight, as well as the body fell to the surface of the gum can cause corrosion and oxidation of the paint. So to make a body from cleaning, polishing to waxing, sealing the glaze and a series of beauty care is necessary. Even if your body has paint coating, it is also take care about it, wash it.

3, tire pressure
For tyres must be using Launch X431 V Pro or Launch X431 PAD tools checked, If the pattern grinding to replace the new tires. Summer tire pressure inside rises as the temperature rises, often have a flat tire accidents while driving speeding, overloading or emergency brake is easy to cause a puncture. Therefore, due to lower tire pressure, or to improve physical properties of tire helium expansion to more stable.

4, the compressor and condenser
After stopping the refrigeration system, every two weeks to make the compressor work more than 10 minutes; To check belt tension periodically compressor; if found frozen oil leakage should be timely treatment; to regularly clean the condenser, to prevent oil, dirt and debris attached to the condenser heat sink.

5, wiper blade
Because many summer rain, automobile wiper frequency of use will be very high, therefore, to strengthen the inspection of the wiper blade is particularly important. In addition to regular inspections, but also pay attention to the cleaning wiper, wiper to prevent the accumulation of dust and impurities affect the wiper effect, or an adverse effect on the windshield before the car. Once the work results of the wiper blade is not ideal, it is necessary to replace the timely repair.

6, car sterilization
It is very important to do a good job in the work of disinfection of vehicles in spring and summer. Should always open the window ventilation, regular cleaning of car exterior and interior. When you wash, you can use a disinfectant scrub, if you have time you can use the Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tool testing. However, we must pay attention to the air disinfection in the car is in the car no one. Disinfection is done, the need to open the window ventilation 5 ~ 6min, the facilities in the compartment with clear water, and then clean the cotton cloth to wipe, so as to remove the residual disinfectant.

When driving the tires have to withstand the pressure from the road surface. Tire wear occurs often does not mean your driving habits problems exist, but this kind of phenomenon but a normal driving inevitable fact, tire wear will gradually aging, and ultimately lose grip. If the vehicle during tire fails, the consequences would be disastrous. When you use Auto Diagnostic Tool to check his car tire whether is deformed or performance degradation of the situation, you can replace them with new tires and avoid failure. Here we will give five warning signal, tip you have the time to change the tire.

1. The tire tread depth
The thickness of the tread must be greater than 1.6 mm, if you often driving on slippery roads on low friction, it is best to ensure the tread thickness is twice the above values. You can purchase a meter to measure the thickness of the tread pattern.

2. tread wear indicator lines
The new tyres have more than one human nature design in the past: tread wear indicator. When the tire is very new or very low degree of wear, these indicator line hardly be found, but to reach a certain degree of wear of the tread these hidden ravine in the line indicated on the show out. Tread wear indicator line is flat rubber with tread longitudinal vertical embedded in the tread ravine. When you use the Launch X431 V+ Pro3 or Launch X431 Diagun III tool to check tire found one to two lines indicating the time, indicating that the tread thickness has been reduced a lot, in this case driving on slippery surfaces should be careful of. If almost all instruction lines are clearly visible on the tire, which means you need to replace the tires as soon as possible.

3. The tire sidewall cracks
The problems on the tyres are not all focused on the tread, and there will be some problems with the tire sidewall. By observing the tire sidewall to find those directly visible to the naked eye crack and cut. These tiny grooves on the tire indicates future cracks leak may occur, and worse even trigger a tyre blowout, the faulty tyres are we strongly want to avoid. So on the tire sidewall crack looks serious, or the cars to a garage as soon as possible replacement tires.

4. Bulge and blistering on tire
In some cases, the outer surface of the tire because of insufficient strength, resulting in higher than normal tire surface projections and foaming. If you failed to timely detection of the vehicle to the repair plant tire failure, intensity of tire surface area is likely to cause sudden burst, high-speed tire blowout even lead to ride under the personnel serious injuries.

5. Excessive vibration and jitter
Vehicle front row during a certain amount of jitter is inevitable, especially in the conditions of poor road conditions. When you already have some driving experience, you can judge for themselves what kind of feelings within reasonable limits of jitter and jitter illustrate how faulty vehicles. Many vehicle shake incentives may exist or the uneven tire axial displacement, it may be a shock absorber problem. But jitter may indicate some problems with the tire inside; even if the tires are not the root cause of the vehicle wobbled also damage the performance of the tire, causing the tire problem shortly afterwards. So if your car there are more serious jitter, jitter appear on the roads especially good roads, once the vehicle to the repair shop use Autel MaxiScan JP701 or XTOOL VAG401 tool check it. Always bear in mind, a greater degree of jitter is often a harbinger of vehicle breakdowns.

All the parts on the car can buy the original factory, only the paint does not have replaceability. According to experts, due to oxidation, the new car will gradually darken paint, it will result in serious paint cracking or even fall off. Through OBD Diagnostic Tool testing showed that: absolute coating products can be a long time to maintain the original color, completely blocked pollutants.

Paint can not avoid the threat of oxidation and weathering, the impact of car paint oxidation once caused it is difficult to easily remove. Polishing, polishing method for removing the oxide layer, the paint will cause a lot of wear and tear. Therefore, conservation of new cars from the start, the regular use of Launch X431 GDS or Launch X431 CResetter II tools to detect. To prevent paint oxidation, weathering, it must be isolated from the outside environment --- paint to prevent oxidation, barrier evaporate. Absolutely coating products are the most effective means to protect the paint against erosion, can long maintain the original paint color. Coating absolute advantage is reflected in the following four points:

First, Absolute coating can be performed at the same time in the beauty of the function of protection, completely blocked against the asphalt, acid rain, gum, pollen and other pollutants, prevent paint oxidation.

Secondly, the absolute coating can paint the mirror effect, delicate texture, bright shine on people.

Third, the paint coating products absolutely no secondary damage, curing just do surface protection film purification treatment, no secondary damage to the paintwork.

Finally, Absolute coating of the warranty period of 2 years or more.

Owners enjoy the car brings a variety of fun, and do not forget to do some of the necessary work, take good care of their car, regular use of Auto Diagnostic Tool to detect car, at the same time to avoid the failure of the car itself caused by traffic accidents, and put forward the following maintenance skills:

Protect the paint
Sun damage on the car paint, be sure to always wash and periodic waxing. If you want to do more thorough protection work, suggested a glaze or coating paint, paint to wear a protective clothing.

Check the brake
Under rainy wet pavement caused friction coefficient between the tire and the road surface is reduced, particularly at the tread has hydrocephalus, the lower the coefficient of friction, a sensitive braking system is particularly important, so one should always check the brake system.

Spontaneous Fire Prevention
Summer is the high incidence of spontaneous combustion vehicles, it is understood, driver's improper operation or car existence hidden danger is the main cause of car spontaneous combustion. Therefore to use the Launch X431 IV GX4 Master or Launch X431 V Pro tool check car oil electric circuit, found that aging line should be timely repairs, to prevent spontaneous combustion.

Using air conditioning
Into the car before you open the window ventilated, open the outer loop at the same time, to stay inside the heat discharge after open air conditioning, the cooling effect is better and faster. When the speed is less than 25 km/h, air conditioning should be placed in a lower gear, to prevent the occurrence of lack of electricity and air conditioning. Driving on rainy days, the window glass is fog, the influence line of sight, at this time as long as the direction of the wind will be dispatched to the windshield, open the compressor air conditioning, can be in a few seconds to achieve the purpose of effective mist.

Prevent evaporation
High summer temperatures, oil and water evaporation will increase, and therefore must take the fuel tank cap Gaiyan tubing to prevent oil leakage; always check the water level of the water tank, crankcase oil oil level, height, brake master cylinder within the brake fluid level and inside the battery electrolyte density and liquid level height, etc. Illegal, want to add and adjust in time.

Note that "freezing"
In the summer, some people think antifreeze irrelevant, can be replaced with plain tap water, in fact, this approach is wrong. Professional preparation of antifreeze is not only low temperature, high temperature characteristics are particularly good. When high-quality antifreeze approaching 200 ℃ in order to be "boiling." In addition, there are rust-proof antifreeze, cleaning effect. Therefore, the choice of the original antifreeze still summer, it can play a "sunstroke" role.

Prevent puncture
Summer surface temperature is higher, automobile tire using the environment even worse, so be sure to pay attention to doing a good job of inspection and maintenance of the automobile tire, regular use of Autel MaxiSys Pro MS908P or Autoboss V30 SPX tools to check the tire pressure, to prevent puncture.

How to determine the type of oil filter? Intend to buy parts to repair shop replaced, but how to buy the oil filter model? And how to use Auto Diagnostic Tool to check the oil filter?

If you have a car maintenance manuals, go directly to view the contents of the maintenance manual, which will have mentioned. If you can not find the maintenance manual, must be carefully selected. Different models has a corresponding filter machine model, if you choose wrong, you can not successfully install, bought filter machine may be wasted.

Here you recommend a Launch X431 Creader VIII or Autel MaxiScan JP701 query tool, which has a self-maintenance functions of inquiry, as long as you put your car-related information can be input into the corresponding maintenance products out.

Many owners like to say fill full when fill oil, usually come added to jump the gun, always want to continue oil into the tank, in order to scrape together a integer. Do you know? Through Auto Diagnostic Tool check data show that gas tank is too full can damage the car, and there are serious damage, there are four points of damage:

1, easy to cause fire
If you add too full of oil, oil is easy to overflow from the tank vent. A waste of gasoline, in case of spilled gasoline encounter fire, it is easy to fire, threatening the safety of life!

2, easily cause clogging of the vent
Once the vent plug, it will generate a negative pressure within the fuel tank, causing oil to poor, even for non-oiled. Car situation appears just after the addition was complete oil beat the fire engine, or a jump a jump phenomenon at high speeds, it is possible that due to the gas tank too full due.

3, canister constitute a hazard
Into the carbon canister is a liquid rather than a gas vapor, carbon canister would constitute a hazard. The canister is to reduce vehicle fuel tank, carburetor gasoline evaporation apparatus matter emissions. Through the Launch X431 V Pro or Launch X431 Diagun III tool check normal carbon tank should be above 50000 km, but after the immersion, immediately scrapped!

4, volatile gasoline easy carcinogenic
The activated carbon canister, generally near the outer circulation air inlet, when the oil is too full, canister saturation, pressure too high and pressure relief exhaust, containing gasoline constituents of air into the compartment, uncomfortable "gasoline" always around you. Oil and gas components have been confirmed to contain benzene and other carcinogens, if every time so that the car refueling, through Autel MaxiSys MS908 or Autel MaxiDas DS708 tool checks show will increase the risk of cancer.

The correct use and maintenance will maximize the performance of air conditioning and extend the service life, and the error use will greatly damage the air conditioning systems, to make life greatly reduced. Automobile Air Conditioning life depends largely on whether the user is able to correctly use and maintenance. You can use the Auto Diagnostic Tool to check car air conditioning performance, air conditioning installed on the car must be carefully read the use of instructions, in accordance with the above instructions.

1, In order to avoid the excessive load of the engine starting, while the air conditioning compressor can quickly into the best working conditions, the first not to rush to the open air. Should put doors, windows open, you can use a fan for ventilation, etc. twenty or three minutes later to sit in the hot gas discharge start the car, and do not rush to close the windows, turn on air-conditioning outside the circle, when the inside and outside the temperature is close, and then close the window, enabling the internal cycle.

2. Select the appropriate air temperature, air conditioning maintenance is the first step. Because of the hot weather, many owners prefer to adjust the temperature too low, which will affect their health. Under normal circumstances, the compartment temperature difference with the outside temperature should be 5 ℃ to 6 ℃, the optimum temperature of air conditioning is 18 ℃ to 25 ℃.

3, Refrigeration and air conditioning wind best blowing up, because the cold air to the sink, the direction of the wind tests are best choice blow face gear, adjust the outlet up effect is best, don't choose the windshield of the block, because the temperature of the windshield is very high, would offset a large refrigeration effect. When selecting wind speed gears don't always use top gear, big air volume refrigeration effect is not good. If only the front occupants to choose 2 or 3 block wind speed is enough.

4, suggested that the owners to best in preparation for parking in front of the 6-7 minutes will close the air, let the remaining heat from the evaporation tank water drying, eliminate and outside temperature, so that you can easily keep air conditioning system relatively dry, can reduce air conditioning odor. Moreover, in front of the parking lot to close the air conditioning, will avoid the impact of the battery and air conditioning, to prevent damage to the engine.

Automotive air conditioning system in use process, the air will flow in the blower, refrigerating system evaporation tank, heating system of the small water tank and the air duct. As long as the air conditioning system blower or the air intake mode choice in the indoor cycle, regardless of whether the use of refrigeration devices, air will enter the system. Through Launch X-431 PAD or Launch X431 GDS tool to check show that the above device surface accumulation with a lot of dust, moisture, bacteria and other dirt, and will cause damage and allergic reactions to human respiratory system and skin, directly affect the occupant's health, and air-conditioning system itself will appear refrigeration effect is bad and a small amount of wind and other fault.

Under normal circumstances every 5,000 km or 3 months to conduct a clean air filter, every 20,000 km or 12 months use Xtool PS2 or Autoboss V30 SPX tool to check the air conditioning, and replace the air filter. This will ensure that you can enjoy the fresh clean car interior environment to ensure your health.

Replace "three filter" according to the use of the car, maintenance and oil quality grade circumstances, automotive air filter equivalent to the human nose, the air entering the engine to go through the first hurdle, Filter the air through the blocking effect of filter paper. When the dust of the filter paper surface of the pores, it will cause blockage, which directly affect the car's engine, unimaginable consequences occur. Because the air filter and direct contact with the outside world, so it is easy to be blocked, through Auto Diagnostic Tool check found engine will accelerate the powerless and idle instability, and other symptoms, the normal work of the air filter can avoid premature engine wear and maintain the best working condition.

The density of the atmosphere contains three different basic particle contaminants that dust, debris and soot. Open highway dust content is low, but emissions from vehicles concentrated, so that the content of carbon particles in the air is significantly higher, and therefore frequently used Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the air filter. The dust concentration in the larger areas such as construction sites, sand area, air filter inspection and replacement frequency to be higher. Also now the majority of automotive air filter is made of paper, when the damp air filter, intake blocked, weak acceleration of the vehicle becomes more serious when the water is drawn into the interior of the engine into the cylinder, since water is incompressible, seriously damaged will cause the engine internal moving parts, engine even scrapped.

Few people noticed it, but auto parts Once the problem occurs, the result is the most serious threats to travel safety, not because these small parts and components affecting the active force of the car, so regular use Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool to check car engine working conditions.

Automobile automatic transmission, manual and semi-automatic transmission car, three different types of operation of motor vehicle, automatic transmission car is easiest, many opened automatic transmission cars have awareness in this regard, therefore automatic transmission car compared with those of other two kinds of car electronic devices will be more, should pay attention to in the maintenance of more, also need to use professional Auto Diagnostic Tool repair, therefore, compared with the other two cars, vehicle with an automatic transmission is more difficult to maintenance, here to introduce some automatic-shift cars maintenance knowledge.

1. Always check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, check the engine oil in the cold state, and transmission oil is needed to oil preheated to about 50 ℃, then to block a rod in each block for 2 seconds in a stop block, the oil dipstick normal oil level should be between the highest and the lowest line, such as not enough, it is timely to add the same quality oil.

2. Correct replacement of transmission oil. Presently preferred method is dynamic change oil, cleaning equipment using a dedicated gearbox, in the gearbox during operation, the old oil full circle, emissions clean, add a new gearbox oil, so oil change rate is as high as 90%, to ensure good oil effect.

3. Master replacement of automatic transmission oil cycle. Automatic transmission internal control mechanism is very precise, with a small gap, so most manufacturers recommend automatic transmission oil change is usually two years or 40,000 to 60,000 km. During normal use, the transmission fluid temperature is generally around 120 degrees Celsius, so the quality of oil in demanding, must also be kept clean, as well as regular use Launch X431 V Pro or Launch X431 V+ Pro3 tools to detect. Secondly, gearbox oil to use after a long time will produce grease, it is possible to form sludge, will increase the friction plate and the parts wear, but also the influence of hydraulic system, make the power transfer is affected. Third, the dirty oil sludge will enable each valve body moving smoothly, hydraulic control affected, so that the automatic transmission abnormal.

Automatic transmission vehicle maintenance and repair in strict accordance with the maintenance manual to repair, encountered do not understand the situation, do not go to their private to deal with, go to a specialized repair shop or 4S shops to consult professional people, but the best maintenance method is usually the correct use of the car, regular use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the car's overall situation.

In the big city in the congestion of the car, the vehicle before and after the gap is basically less than one meter, and the slope of the overpass is very large, parking brake is particularly important. However, due to various reasons, the handbrake will appear when no use. In the daily inspection and maintenance of the vehicle, don't forget to use Auto Diagnostic Tool to check the performance of regular handbrake.

First, determine the operating position of the handbrake lever. Generally, when the handle is pulled three-quarters of the entire trip, the hand brake system should be in a normal brake position. Should first find out the work point, the general 5~7 case is normal position. Then check the brake mechanism efficiency, also is have a look handbrake to work effectively. The car drove up to the steep, good road conditions of the slope, step on the brake pedal, the neutral gear, pull the hand brake handle to just to determine the position of. Slowly loosen the brake pedal, if the car did not happen sliding, that means the hand brake performance is good.

Check the handbrake sensitivity, since it is very important to the slope. On flat roads slow driving, slowly pulling handbrake handle and feel the sensitivity and the junction of the handle. If it is found that the brake braking efficiency or sensitivity is not ideal, can regulate the handbrake thread through Launch X431 PAD or Launch X431 GDS tools to solve.

Adjust the hand brake wire. If found in the test the brake is not sensitive, can be solved by adjusting the handbrake arrows, below the hand brake handle with an adjustable compensation institution. Adjust the need to remove the handle decoration cover first, then use tools to adjust the length of stay, in order to ensure the hand brake is in the best working state.

Ordinary driving, the handbrake usage is very high, but the handbrake is not universal insurance, its performance will decline with the increase of using the number of times. Most of the time, because the system failure or improper use and don't effect, this is also the major hidden danger of the accident, so owners should regularly use the Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools maintenance check handbrake.

Automotive shock absorber is used to suppress the shock of spring when the shock and the impact from the pavement. The spring can be used to filter the vibration of the pavement, but the spring itself will have a reciprocating motion, and the shock absorber is used to suppress the spring jump. Through Auto Diagnostic Tool checking, the shock absorber is too soft, the body will be jumping up and down, shock absorber is too hard will bring too much resistance, interfere with the normal work of the shock absorber. Teach you how to maintain the working effect of shock absorber and how to check it.

1, Oil seal gasket, sealing gasket rupture damage, storage cylinder cover nut loose. May be oil seal, seal gasket damage, should be replaced with new seals. If you still can not eliminate oil leakage, should pull out spring strut, if feel the card or not at that time, light and heavy, then, using the gap between Launch X431 V Pro or Launch X431 Diagun III tool to check the piston and cylinder is too large, shock absorber piston connecting rod for bending, the piston connecting rod surface and the cylinder have scratches or marks.

2, Press firmly on the bumper, then release, if the car has 2 or 3 times to jump, then the shock absorber works well.

3, when the car slowly driving and emergency braking, if the car more intense vibration, there is something wrong with the shock absorber.

4, Remove the shock absorber to its upright, and the lower end of the connecting ring folder on the vise, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than pressed down resistance, such as resistance to unstable or no resistance may be internal shock absorber valve parts lacking fuel or damage should be repaired or replaced.

5, in determining the shock absorber problem or failure, should first check the shock absorber for leaks or traces of old oil spills.

6, To make the car drive 10km on the poor condition of roads on the road parking, touch the shock absorber shell, if not very hot, no resistance in the shock absorber, shock absorber does not work. At this point, can be added to the appropriate lubricating oil, and then test, if the shell fever, for the shock absorber internal lack of oil, should refuel; otherwise, the shock absorber failure.

7, if the damper does not leak phenomenon, should check the shock absorber connection pin, connecting rod, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without injury, the valve seal is good, the valves and valve seat are tight fitting and Save Dilatation shock absorber spring is too soft or broken, take grinding to repair or replace parts of the approach according to the situation.

8, In addition, shock absorber in actual use will rattle the fault, which is mainly due to the shock absorber and the steel plate spring and frame or shaft of the collision, the rubber pad damage or loss and damper dust-proof cylinder deformation, caused by insufficient oil should be to identify the reasons, to be repaired.

9, shock absorbers after the inspection, repair should be in a special test stand performance test, when the resistance frequency at 100 ± 1mm, which stretch stroke and stroke compression resistance should meet the requirements, showed normal shock absorber.

I suggest that you use by bumper way to check on how the working conditions of the shock absorber. Because this approach is simple and relatively less time-consuming, but also very intuitive and accurate test results. You should regularly check the shock absorbers have no oil leakage, and if there is leakage oil will affect its work, should go to 4S shop use professional Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tools for maintenance.

The engine timing belt also called a toothed belt, The crankshaft and camshaft are connected by the above tooth groove. We know that the engine is in normal and stable work, the movement of the piston position, the valve open and close time, fuel injection and ignition time must be synchronized, and this is accomplished through the timing belt, you can use the Auto Diagnostic Tool to check the timing belt working performance.

Timing belt belongs to the rubber parts, with the increase of engine working time, timing belt and timing belt accessories, such as timing belt tensioner and pumps will wear or aging. If can cause the vehicle broke down after fracture belt, the engine internal valve damage, serious can cause the abandonment of cylinder cover. Not only to spend more, but also a long time to repair. Therefore, we need to use the Launch Diagnostic Tool or Autel Diagnostic Tool regularly to check and maintain the timing belt.

Check automobile engine belt consists of two elements:
First, check the belt tension, then you can use the thumb, strongly pressed the middle two belt pulleys. The pressing force of about 10kg, if the reduction of the belt is about 10mm, is considered proper belt tension exactly. If excessive pressure is considered insufficient belt tension. If the belt hardly occurs reduction is considered excessive belt tension. When the lack of tension, the belt is prone to slipping. The tension is too large, it is easy to damage various auxiliary bearings. For this reason, it should be related to the adjusting nut or bolt loosen the belt tension adjustment to the best state.

In addition, it must be noted that the wear of the belt. Old belt badly worn, the belt and pulley contact area dropped. Then as long as the force of a press belt, the belt will sink deep into the pulley groove. If the belt rubber is aging, must promptly replace the new belt.

Xtool PS2 or Autoboss V30 SPX tool inspection data show that cars generally every 80,000 km replace the timing belt; five-valve cars are generally replaced every 60,000 kilometers per timing belt. It should be noted when replacing the timing belt, appendages such as tension pulley, water pump should be replaced together.

Nano fuel additive is a functional material to make up for the defects of the fuel in some properties and to give some new properties of fuel. It has washing, dispersion, emulsion breaking, antioxidant, promoting burning, corrosion, rust, lubrication, cleaning function. According to Auto Diagnostic Tool tests show that nano-saving device is mounted on the pipe of the car, after the installation of this equipment can purify exhaust gas by 50% -90%, 10% -30% fuel savings, enhance the power of 10% -30%, reduce engine noise, suppression coke production, clean combustion and prolong engine life.

Maintenance and good driving habits is the key to saving, The best fuel-efficient way is at ordinary times to use the Launch X431 PAD or Launch X431 GDS tools check vehicle, to develop good driving habits. Do not always emergency braking or hard acceleration. Energy-saving cars "four bogey." A bogey, since often require hard acceleration, braking, fuel consumption ratio will increase 2-3 times uniform; two bogey, pay attention to traffic conditions ahead, without prior dodge or slow down in advance, the car will see the red light or experience, rely on the emergency brakes, natural fuel soared; three bogey, high speed and low-speed operation, the engine idle for a long time; four bogey for a long time over economic speed driving.

Nano fuel additives Product features: can effectively protect the engine, it can increase the useful life of an automobile engine and some 5 - 10 years, based on Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool checks show can effectively fuel-efficient 5-16.6%, remove carbon deposition by more than 95%, the noise of the engine has also dropped. Nano fuel additive has a clean, dispersion, emulsion breaking and promote burning effect, after clear the carbon deposit in fuel oil, through the "microburst", promote burning, finally to reduce emissions, eliminate exhaust black smoke.

The car drive belt is responsible for all parts of the movement, if it bad the car can not move. Because the engine is driven by a belt drive all kinds of auxiliary mechanism, such as an air conditioner compressor, power steering pump, alternator, etc., if the belt is broken, or there has been slippage, will be related to the loss of the auxiliary mechanism, or its performance decline, thereby affecting the normal use of the car. Therefore, it is necessary to check the drive belt regularly using Auto Diagnostic Tool.

Belt inspection method is very simple. First, check the belt tension, select the longest unsupported belt span intermediate applying moderate pressure with your thumb, if the reduction is about 10 mm in the belt, that the belt tension is just right. If the belt tension is too large, or too loose, it could result in slippery tooth, transmission is incomplete. And adjust the belt too tight, so that the belt is easy to tensile deformation, but also accelerate the pulley and bearing wear. For this reason, it should be related to the adjusting nut or bolt loosen the belt tension adjustment to the best, if you are not sure the best, you can use the Launch X431 V+ Pro3 or Launch X431 CResetter II tool check the belt the best condition.

In addition, in daily inspection should pay special attention to the wear of the belt. Because if the belt wear is serious, it will cause the belt and the belt pulley contact area to drop sharply. At this time, as long as a pressure belt, the belt is deep down to the groove of the belt pulley.

Also, if you find the belt surface cracks and spalling cracks appear phenomena such as sound or belt slipping occurs, indicating the belt may be broken and must be replaced immediately. If not promptly replaced, the belt once in a moving way break, the vehicle will not be normal driving.

In actual use, check and replace the automobile belts are very complex, generally professionals using the Autoboss V30 SPX or Autel Maxidiag Elite MD702 tool operation. Moreover, because the price of the belt is not particularly expensive, often change in time before the arrival of the service life of the belt is a common choice.

Automobile circuit usually have starting circuit, power supply circuit, lighting and light signalling device circuit, ignition circuit, auxiliary circuit device, electronic control system circuit, instrument information system circuit composition. So many friends in the process of driving the car will be found auto electrical systems fire, when people are very anxious, do not know what is going on. So today we analyze why the car circuit system catch fire, of course, need professional OBD Diagnostic Tool to be checked.

Among the car ignition accident, car circuit fire occupy a large proportion of spontaneous event. This circuit is aging and the car circuit load is too high is the reason. First, since the engine work, the ignition coil high temperature, easy to make high-voltage ignition wire insulation softening, aging, crack damage, ignition high-voltage insulation breakdown easily produce high-voltage leakage, short circuit leading to spontaneous combustion ; second, the car has a growing number of electronic control technology, intelligent vehicle widely used, Launch X431 Diagun III or Launch X431 Creader VII+ tools to detect data show a substantial increase in the power consumption of automotive electronics accordingly. Auto electrical systems on limited load space, automotive microcomputer, electronic components, various sensors circuit systems are likely to cause damage, since a large number of cars increase the variety of additional electronic equipment, may also increase the burden on car circuit, causing spontaneous combustion fire.

Car circuit maintenance is very important, a lot of the cause of fire is circuit aging, many friends think now car maintenance is the car's appearance maintenance, do essential for the maintenance car circuit, you can also use Autel MaxiSys Mini MS905 or Autel MaxiSys MS908 tool regular inspection car circuit to ensure the safety car circuit.

Now city traffic condition is getting worse, car stop-go situation has become the habit of the driver. So, portable, easy these two features automatic car has quietly become the first choice for most people. Although automatic car easy and convenient, but because of the automatic transmission system is very sophisticated, if the automatic transmission fails, we need to use a professional OBD Diagnostic Tool repair, and expensive, and therefore, the automatic transmission need to be more careful care and maintenance.

The automatic transmission oil can not only play the role of lubrication cooling, but the main thing is to transfer power between the engine and gearbox. Lubricating oil temperature is generally around 120 degrees Celsius, so demanding on the quality of the oil, and must be kept clean. First frequently used Launch X431 V Pro or Launch X431 IV GX4 Master tool to check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, need to be preheated to about 50 ℃, the gear lever again after a short stay in each block in the parking and the oil dipstick corresponding normal oil level should be between the highest and the lowest line, if not, should be added in time.

In most cases, when we replace the automatic transmission oil is to remove the screw automatic transmission oil pan to miss the old oil then add new oil, but this can only put about a small part of the new oil, and there Most of the old oil remains in the gearbox. If demolition sump oil change way, you can put 70 percent of the new oil, so as to ensure the transmission of health. Presently preferred method is dynamic oil change oil change, using a dedicated gearbox cleaning equipment, the full cycle of old oil, drained and then add new oil, so that the oil change rate of 90%.

As the vehicle traveling road is rather special, road congestion, poor air quality, is easy to cause transmission oil oxidative deterioration, according to Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool inspection data indicate that the deterioration of the transmission oil increased wear of friction between the film and increase fuel consumption, if not to change new gearbox oil for a long time, will cause oil particles increases and block oil, blocking the plunger, and even a shift impact, so the transmission oil must be replaced periodically.

Configuration 8V engine and manual transmission Citroen. As the hot weather, frequent use of air conditioning systems, and found that air conditioning cooling effect is getting worse, specifically the phenomenon as follows: Press the air conditioning and refrigeration switch (Electric No. 584), air conditioning compressor to operate properly at first, but with the extension of working hours, use Auto Diagnostic Tool testing data showed that the air conditioning compressor electromagnetic clutch is frequent absorption and separation, intermittent failure caused by air conditioning refrigeration function.

Air conditioning system circuit diagram, the air conditioning compressor electromagnetic clutch frequent closing and analyze the cause of the fault separation, according to the possibility of making maintenance plan, and then to repair work as follows:
1) Check the engine compartment fuse box (Electric No. 52) of the fuse F12, normal. In the case of opening and closing of the ignition switch, voltage with a multimeter block measuring the terminal voltage connector 113 BIIA results were obtained for the battery voltage and 0V, normal. In the case of opening and closing of the ignition switch, air conditioner switch assembly measuring terminal 7 NA1 voltage, battery voltage, respectively and 0V, normal.

2) Replace the air conditioning switch, the failure remains. Replace the air conditioning control box, the problem persists, that failure has nothing to do with these two parts.

3) In the case where the engine is not running and the operation of detecting the line pressure of the refrigerant, the refrigerant is obtained by the static pressure of 500kPa, the dynamic pressure of the refrigerant: a high pressure of 1300kPa, a low pressure of 140kPa. The above measurements were compared with standard values, in line with requirements. This ruled out due to the refrigerant pressure abnormalities lead to the air conditioning compressor electromagnetic clutch pull and separate frequent failure factor.

4) Check the coolant temperature control box (appliance No. 53) and the related wiring. External line there is no problem. Replacing the coolant temperature control box test, fault still exists. Continue to check the fuse box in the engine compartment fuse, no abnormality was found. Check the coolant temperature control box plug voltage terminal 15N4,15N15 in the ignition switch is turned on is the battery voltage, Launch X-431 PAD or Launch X431 GDS tool coolant temperature measurements show that the control box supply line is no problem, thus excluding the coolant temperature control box failure factor.

5) Check the coolant temperature sensor (electrical No. 910 for coolant temperature control box to provide coolant temperature signal) and the line, there is no obvious anomalies. Replace the sensor, the fault persists.

6) Check the evaporator temperature sensor (Electric No. 912) and the line of work, there is no appearance problem. Measure the resistance with a multimeter evaporator temperature sensor found resistance is too large. Replace the evaporator temperature sensor, test, fault completely disappeared, ending maintenance work.

The evaporator temperature sensor is a negative temperature coefficient thermistor, its resistance decreases with increasing temperature. When the resistance is too big a problem occurs evaporator temperature sensor, the signal voltage will become larger, air-conditioning control box will mistakenly believe that the evaporator temperature is less than 1 ℃. To prevent evaporator freeze, air conditioning control box off the air conditioning compressor electromagnetic clutch operating power. After a child, Autoboss V30 SPX or AUTOBOSS V30 Elite tool checks found that the evaporator temperature is higher than 3 ℃, began to turn on the air conditioning compressor electromagnetic clutch pull. Again and again, the results of the air conditioning compressor frequent start of the fault phenomenon. The evaporator temperature sensor is a vulnerable part, only after the damage can be replaced.

Everybody for car batteries and air filter should be familiar with. So we usually listen to music while driving in the open air or blowing cold air, which must support the job by a car battery. And if the battery is no electricity or damage, the car is unable to start, so the need for regular use Auto Diagnostic Tool to check the vehicle battery. Then the air filter plays a filtered air entering the engine, to provide clean air for the engine, reducing engine running wear. Today we take a look at the two components of the maintenance guide.

Car battery:
General, automotive battery life is two years. Some owners usually well maintained, can extend this use time. If maintenance do not get bit, less than two years to be replaced. If the battery has been aging and not timely replaced, repeated charging and discharging can damage the internal battery plates and an electrolyte. through Launch X431 Diagun III or Launch X431 V+ Pro3 tool check data show that: the battery capacity will be reduced and eventually run out of power, the engine can not be started.

Air filter:
General car mileage of forty thousand kilometers or two years can be considered to replace the air filter. If it often in some dusty environment, the replacement cycle would go ahead of some. If no timely replacement of the air filter, increases mileage and filter clogging. And reducing engine power, accelerate the ability to reduce, reduce fuel economy, cylinder due to dirt and damage, air supply is insufficient.

So now we should all know the importance of car batteries and the air filter. Just remember that your battery and air filter coming two year when we should use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check usage, it should be replaced. Usually in the car maintenance cycle time, we must check the battery and air filter, if there is a serious aging, damaged the situation, it should be replaced.
