Brake system maintenance Note

First: high temperature protection of brake pads
Prevent the brake system corrosion, prevent the brake disc from high temperature surface card die, eliminate the brake piece of screaming, maintain good lubrication lasting, need to be resistant to high temperature up to 1400C above the ceramic component products. Therefore, to regularly using the OBD Diagnostic Tool check the thickness of the brake pads or brake shoe. In the normal driving situation, the front brake of the brake pad life is 50000 - 30000 kilometers, the service life of the brake pad is 150000 - 120000 km. Once the brake wear to the limit should be replaced in a timely manner.

Second: brake wheel cylinder lubrication and maintenance
Lubrication of brake wheel cylinder shaft and cup, keep the wheel cylinder liner soft, extend the service life of the pump, need to use fully synthetic brake wheel cylinder lubricating oil.

Third: Clean brakes
Quick cleaning brakes, brake drums and any parts of grease, dirt and friction dust, keeping the brakes heat dissipation; eliminate harsh noise brakes, promote uniform brakes, use Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the brake system.

Fourth: brake oil change
Brake oil has water absorption characteristics, long time no replacement will corrode the brake system for traffic and security. It recommends that owners generally, to replace a brake fluid every 20,000 km. Mainly to ensure the cleanliness of the brake fluid.

Fifth: tire screw, brake disc and ring contact surface rust lubrication
To prevent corrosion and prevention screw and surface heating stuck, convenient disassembly, high temperature of above 1100c aluminum product ingredients, to guarantee and the brake contact area and improve the braking force, the need for regular use of Autel MaxiSys Mini MS905 or Autel MaxiDas DS708 tools to detect the brake system performance.

Car wiper and battery maintenance guide

How to identify under what circumstances need to replace the wiper?
1. From the wiper itself, the symptoms of damage. Identify whether there are cracks, cracks, rust, deformation, adhesion, color and so on; with ears to distinguish wiper when use whether jumping, such as jitter abnormal sound; the use of OBD Diagnostic Tool to check whether the hardening of the rubber, etc..

2. In the process of using see symptoms from the windshield. , look to whether have a slender stripe, is hard to see the outside world, this is because there is foreign body on the wiper or edge frayed, processing method first cleaning the edge part, if you do not eliminate symptoms will need to be replaced.

3. After the rain wiper is wiped, leaving a trail of water,  this is because the deformation of the rubber. If the rubber is not in contact with the glass surface, this suggests that the bracket deformation, wiper need replacing.

4. Check the wiper blade. The wiper pull up, finger touch on the cleaned rubber wiper blade, check whether there is damage, but also check whether the rubber blade has good elasticity, if the leaf aging, hardening crack, it should be replaced with new ones.

Check the battery electrolyte level should pay attention to what areas?
Check the electrolyte level, parked his car in a horizontal road, engine, by observing the battery shell on the scale line. Position, if it is difficult to determine the liquid surface of a battery, and with the aid of a lighting to see, can also use the Launch X431 GDS or Launch X431 V Pro tools to check the electrolyte level.

New battery is provided with an indicator, can through the indicator to check the status of the battery. Indicator on the green dots obviously show that the battery in good condition: a green dot blur, shows that lack of electricity: dots become transparent or yellow, indicate the need to replace the battery.

Its different battery indicator is displayed may be different. through Autel MaxiSys Mini MS905 or Autel MaxiScan JP701 tools real time data display, if the battery indicator is blue when normal, insufficient amount of electrolyte is red, when white needs recharging. There's battery level indicator at the square hole below the liquid level is too low, when the indicator of the level below the square hole for liquid level is too low, as it happens and square hole level as the standard, more than at the bottom of the square hole and filled with liquid mouth when too much for the amount of electrolyte.

How to maintain your car sunroof

Car sunroof is a very common configuration comfort. So the question is, did you use Auto Diagnostic Tool maintenance skylight? Here we come to the maintenance of the skylight and note to do a simple introduction.

One. Skylights use a long time, at its rails, the gap will be deposited in a lot of sand or foreign objects, such as occasional clean-up, will wear the sunroof member. It should be cleaned regularly lubricated around and avoid sand deposition, to extend the service life of the sunroof seals. Generally every six months, to use gauze or cotton dipped in water to wash the sealing tape or slide, rub after a little grease can be applied. Can be used for a fine talc, can prolong the service life of the sealing ring.

Two. Use skylights biggest concern is leaking, proper use and maintenance of skylights can effectively avoid leakage. Before entering the rainy season, in addition to clean up slide, seal gap is the foreign body, but also a harness protector or talcum powder sprayed on the seals and other components.

Three. Before turning on the skylights, should pay attention to whether the roof has obstacles to the operation of the glass panel. Sunroof panel design has isolated the heat and ultraviolet function, please use a soft cloth and cleaning agent cleaning, never sticky or have corrosive cleaning agent, you can also use Launch X431 V+ Pro3 or Launch X431 V Pro tools to detect the sunroof.

Four. On the very bumpy road best not to completely open the sunroof, otherwise may have skylights and slide rail vibration between related parts deformation caused by the too big to even make the motor damage. In addition, rain or cleaning vehicle when it is forbidden to open sunroof.

Skylight is not just a piece of glass so simple, its structure is quite complex, once skylight some failures,  using Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool maintenance and replacement costs is too high, panoramic sunroof maintenance costs even higher. Therefore, the maintenance of skylights not be ignored.

How to prevent the engine temperature is too high in summer

Hot summer temperatures, the hot sun road car to withstand the ordeal, the engine temperature is too high is summer cars need to pay special attention to matters, prevent the engine temperature is too high to pay attention to the following four bogey.

A bogey: boil immediately when opening the lid, add water
Radiator in the inland waters after boiling, internal pressure to a certain extent, if at this point immediately open the radiator filler, from hot water can, causing burns. The right thing to do is to find the tank water boiled, immediately opened the hood to increase air flow, when the water temperature drop is no longer a boil, then use a wet towel to do hand pad, radiator water cover unscrewed a first block and release of water vapor, a moment is opened entirely. To avoid water mouth above will face at the same time, to prevent scalding hot water overflowing face.

Second, avoid: boil after flameout immediately
Some drivers found after boiling, thought is immediately shut down. Want to know: Engine why boil is due to high temperature of inner water jacket is jacketed tank, wall, cylinder head temperature too high. At this time if the flameout, parts are in expansion in the state, with the gap is very small, after the shutdown will result in some soft metal off, and some will even cause sticking cylinder. So that after boiling, don't immediately turn off, should remain idle.

Three bogey: when the engine temperature is too high, pour cold water poured engine
Car launch forget to add cooling water temperature has been found to be too high, so he to the engine block, cylinder head and poured cold water to cool. Little do they know the consequences are serious, may cause the engine block because the quenching burst, causing irreparable consequences. Engine temperature will overshoot bad head gasket, burn Bush, machinery accidents; temperature is too high, causing the intake air drops, power is reduced; the tank boil, boiling coolant evaporation overflow; Launch X431 CResetter II or Launch Creader VII tool test showed that the engine will meet the various components gap decreases, increased wear and reduce engine life.

Four bogey: bogey water tire cooling when the temperature is too high
When the tire temperature is high, are due to the installation is not accurate, the speed is too fast and other reasons, but also the hot natural climate caused by. If in tire temperature is high throw cold water is bound to cause fetal internal structure due to sudden changes, resulting in the deformation matrix inside each ply between a, cause early damage to the tire, even the cord stripping. In addition, should also pay attention to the tire pressure and temperature, otherwise easy to explode accident. Once burst, light affects the speed; that will have a serious accident. During the rest of the journey, check the tire temperature and pressure in time. If it is found that the tire temperature, tire pressure is too high, can not take deflation and pour cold water on the way, should choose the shade, parking, the tire temperature, pressure drop of natural; such as wading, should be tire temperature decreasing after wading to prevent tire early damage.

Hot summer temperatures, in order to prevent the engine temperature is too high, it should pay attention to the following points: 1 plus sufficient cooling water; 2. Autel MaxiSys Mini MS905 or Autel MaxiDas DS708 tool to check the thermostat is normal. 3. driving in the instructions and pay attention to water temperature readings, requires no more than 95 ℃. 4. In exceptional circumstances, in order to strengthen the cooling air convection, can lift the hood to facilitate ventilation.

Car burning oil reason and solutions

The engine is the heart of the vehicle must be protected. The quality of the oil not only can reduce engine wear, increase engine efficiency, by OBD Diagnostic Tool to detect, but also to save fuel consumption, extended drain intervals and help keep the engine clean and prolong engine life, long-term performance of the engine as new.

There are three cases car burning oil
1, the valve seal leakage at the oil, because the poor quality of the valve seal, or the engine temperature is high, or exhaust vent is blocked leading to the greater impact of the valve seal.

2, Crankshaft ventilation mechanism can not be filtered out of the oil, leading to oil is sucked into the inlet, the only use Launch X431 V Pro or Launch X431 Diagun III tools to detect oil filter components, to eliminate failures or improve efficiency.

3, From piston engine oil leakage, for this performance, throttle only exhaust side have the carbon deposition, but the most damage, the main reason is lack of the inferior quality or process precision of piston and piston ring, under the turbine, the piston ring of gas oil energy is larger, the destructive force of the piston ring of piston is bigger, more heavy oil burning.

Overall, the engine burning oil to avoid is the use of qualified and suitable lubricants, and changed regularly. But note that the different cars engine design, therefore, in view of the model in different countries, the cost of repair and repair after the effect of the difference is very big. Universal significance and practical advice is to use good oil and regularly replaced.

Some burning oil was designed to be, this is actually the main part of the current owners complaints: obviously the vehicle does not have any fault, but the oil consumption is particularly large. So for the engine easy to have a fever, usually to use the Autel MaxiDiag Elite MD802 or Autel MaxiSys Mini MS905 tool to check the work condition, the regular check the oil consumption is normal, etc..

Summer car maintenance 6 small common sense

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.

Timely attention to automotive air filter maintenance

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.

Maintenance and inspection method of automobile shock absorber

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.

Why the car circuit system will catch fire

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.

Car special parts cleaning and maintenance skills

With the development of automobile speed, the automobile maintenance has become one of the most concerned about the topic. In addition to the regular repair shop to do routine maintenance, some small parts of maintenance is also worthy of attention, because of the maintenance of these places, if necessary, use Auto Diagnostic Tool to detect, the relationship with you while driving comfort and safety.

Dashboard cleaning needs careful
One very important part in the car interior is the dashboard, cleanliness which directly affect the health of drivers, as well as occupant of the car interior environment overall effect of visual experience. Dashboard complicated structure, difficult to clean up. Little attention to the dashboard will find only rags and sponges can clean small, you can use the Launch X431 V+ Pro3 or Launch X431 V Pro tool to check, some places need to use "special tools" clean.

With different thickness of wood or ruler to its head, repaired, or oblique triangular rectangular points such as different styles, and then wrapped with a clean cloth, both to improve the cleaning effect, and will not damage the site to be cleaned .

Washing the carpet needs skill
Inside the car most likely place is dirty carpet, if carried out with a vacuum cleaner brush head cleaning process, you can make more dirty carpet looks not so dirty. For more dirty carpet, you can only use a special detergent. Usually first with detergent to remove dust, then spray the right amount of detergent, scrub clean with a brush, and finally with a clean rag and wipe off the excess detergent can be, so that we can make the carpet after washing is clean and soft as before.

It should be noted that the carpet not completely into the water scrub, on the one hand will destroy the carpet adhesive internal layers of different materials, on the other hand will make the carpet for a long time does not dry and affect the results, causing the car moist, even affect automotive components performance, you need to regularly use Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool to check the car's performance.

Three methods of self testing whether the car burning oil

Generally have the phenomenon of burning oil vehicle exhaust will have different degree of "blue smoke" symptoms, oil consumption increased significantly, a short period of time will have to add oil. Vehicles burning oil, it will lead to increased coke combustion chamber, economy cars, power drop, excessive exhaust emissions and other adverse consequences. Automotive expert introduces three methods of self testing whether the car burning oil, need to use the OBD Diagnostic Tool to detect, is simple and effective, may wish to try.

The first method is: when driving in the morning, the exhaust pipe appeared darker blue smoke, blue smoke disappear after a while, that day may not happen again, but the next day, the third day morning appeared This phenomenon, which shows that the vehicle has appeared the phenomenon of burning oil.

The second method is: When the vehicle is traveling,The driver stepped on the accelerator when the forced exhaust a lot of blue smoke, which shows a vehicle burning oil phenomenon has been more serious.

The third method is: In addition to the exhaust pipe to take blue smoke, you can see the blue smoke from the oil out mouth pulsation. In this case, engine damage has been very serious.

Once a car burning oil phenomenon occurs, it is necessary to go to 4S shop use the Launch X431 V+ Pro3 or Launch X431 GDS tools to detect and repair.

The poor sealing of the cylinder is mainly caused by the burning oil. Mainly with the gap between the piston and the cylinder wall is too large, the piston ring seal improperly installed or worse, oil on the cylinder wall into the combustion chamber, causing the phenomenon of burning oil.

Auto repair experts said, causing the vehicle to burn the oil with the driver's driving habits. the driver to develop good driving habits, while possible, choose a good quality oil, the appropriate use of a slightly larger engine oil viscosity to increase piston seal between the cylinder wall,; ground check the dipstick regularly change the oil and oil filter, Genuine spare parts to replace the oil filter; timely use Autel MaxiSys Mini MS905 or Autel MaxiDiag Elite MD802 tools to detect vehicle performance, can effectively avoid the phenomenon of burning oil.

Fuel filter basic maintenance of common sense

Fuel filter replacement cycle
Fuel filter replacement is recommended once every 10,000 kilometers, built-tank fuel filter replacement 4W - 8W km. The differences between different models of the maintenance cycle may be slightly, your car when need to replace the maintenance, please via OBD diagnostic tool understand.

To conduct a comprehensive maintenance, fuel filter and oil filter, air filter, machine commonly replaced at the same time. Disassembly to replace the fuel filter is more complex, not easily do it yourself, you need go to repair shop and let professionals to operate install.

The necessity of replacing the fuel filter
Fuel filter according to the different filter can be divided into gasoline fuel filter and diesel fuel filter, home cars use a fuel filter, fuel filter are divided into built-in and external tank.

The vehicle with the use of the growth of the age, with increased mileage and fuel filter long-term work, to reach a certain life cycle, will cause the car to accelerate weakness, increased fuel consumption, noise increase, reduce handling performance, you can also use the Launch X431 GDS or Launch X431 V Pro check the fuel filter performance.

Fuel filter purchase considerations
1, before the purchase of goods, be sure to verify the car's model, displacement and other information to ensure that the correct types of accessories available. You can check the maintenance manual.

2, high quality fuel filter, poor-quality fuel filter often leads to oil poor, lack of motivation or even turn off the car. No filter impurities, a long time, oil and fuel injection systems may cause corrosion damage.

3, when the feeling of speed significantly reduced, poor acceleration engine, cars with weakness, it may be already clogged fuel filter, and the need for timely use Autel MaxiSys MS908 or Autel MaxiSys Mini MS905 tool checks.

Daily maintenance SUV models of small tips

SUV models currently in the automotive market is one of the more popular models, SUV sales ratio is constantly growing, and some consumers buy first goal is to SUV models, and the OBD diagnostic instrument has become owners of the necessary tools.

1, Car cleaning agents to choose the appropriate
Some people think only choose expensive, but do not know that only the right is the best. Select detergent is also very important if you choose properly will result in material damage to the car interior. Because each part of the SUV automotive interior materials are not the same, if you choose a larger alkaline cleaners, although there whitening. Decontamination effect, but too much alkaline cleaner will soak flannel, leather chairs, ceiling, eventually harden, crack. Select the best choice cleaner cleaning fluid PH value does not exceed 10 is more suitable. You can use the Launch X431 GDS and Launch X431 IV GX4 Master check, determine the car without any problems.

2, Periodic replacement of the lubricant
SUV usually take four wheel drive 4WD design, according to different road conditions. Most of the SUV is equipped with anti-slip rear axle differential device, in case when a wheel slip, to ensure that there is still another round grip; and such a situation prone to high temperatures, damage to the differential device. Therefore, consumers should be based on the original factory to recommend the use of a suitable lubricant, good lubrication, high temperature resistance and other characteristics, can we truly differential protection and automatic gearbox.

3, dashboard protective agent
Cleaning the car dashboard is also very important. After cleaning the car SUV but also coated with a protective agent. But the choice of protection may also need to be cautious, modern leather protective agent points emulsion, oil and water three. ? So how to choose it emulsifying agent with protection but strong alkaline cleaning function; oily protective agent contains a solvent component, will erode the decomposition of resin and pigment to produce leather on leather fade, according to choose the right protective agent, if the consumer those who do not know how to distinguish between, you can use Autel MaxiSys Mini MS905 and Autel Maxidiag Elite MD701 check, routine maintenance is also very important.

How to timely discovery brake failure

For brake failure, we may only appear in the braking force of brake or abnormal noise will be found. If you are traveling at high speed and other conditions, it is very dangerous! In fact, we usually use the Auto diagnostic tool you can determine the brake system problems, and these details are likely to be ignored for everyone.

First, when the brakes shudder
This situation occurs mostly in old car, because the use of wear, brake disc surface roughness has a certain degree of misalignment. It is proposed that, as the case opt lathe sanding disc technology, or replace the brake pads.

Second, when the brake quickly stopped, the steering wheel will always to the side deflection
In fact, this situation is what we called "partial brake", the main reason for the failure is about the brake system Cylinder uneven forces on the brakes caused. And in the process of moving due to the rotation speed brakes, wheel cylinder uneven role in the fast friction difference is very small, we can hardly feel it. But when the vehicle stopped quickly when the difference is obvious, that the speed of the wheel stopped on one side of priority, the steering wheel will deflect. This may need to Launch X431 GDS and Launch X431 V Pro tools to detect.

Third, driving need heat 10 minutes before the brake force
Is provided by the engine brake system pressure to promote calipers grip brakes, or push the brake drum friction brakes. So like the above conditions, may provide pressure transmission pipelines loss of pressure occurs, resulting in not timely provide braking force. This situation should be checked at the pretext of the vacuum booster hose and brake master cylinder engines have cracks or loose condition.

Fourth, the brakes do not return
Step on the brake pedal, the pedal does not rise, no resistance, a phenomenon that the brakes do not return. Need Autel MaxiSys Mini MS905 and Autel MaxiSys MS908 tool to determine whether the brake fluid missing; whether the brake wheel cylinders, pipes and joints leak; whether the master cylinder, slave cylinder parts damaged.

How to maintain the vehicle fuel system

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.

How to solve the automotive air conditioning odor and refrigeration poor

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 .

Winter Car Tires Maintenance--Keep a Stable Pressure

With the striking of the strong cold air, most car owners are busy to acquire "winter clothes" for their loved cars and more and more online auto diagnostic store have offered all kinds of tools for car owners to check whether there is something wrong with their loved cars, such as the Launch X431 GDS, Autel MaxiSys Mini MS905, Launch X431 Diagun III Diagnostic Tool and Scanner, etc. However, among most of the maintenance details, they tend to ignore the maintenance of the “Shoes”-Tire. Here we must remind you that the tire maintenance among all the vehicle maintenances, it is the most important.

In the cold winter, the rubber of the tire will be harder than summer, though many cars have equipped with the tire that is suitable for full seasons, the frozen wet pavement will test on grip of the tire. As a result, it is very necessary to change a winter tire, and if you really don’t want to change a new tire in winter, you also need to pay attention to the tire maintenance and the safe use.

In winter, the rubber will become harder and relatively fragile, as well as a lower friction coefficient, which require the tire pressure should not be too high, but also not too low. Because under a cold weather, the tire pressure will be too low, which can accelerate the aging of the tire, and add the contact with the floor, thus reduce your car tire life.

Besides, you should also clean the inclusion of the tire in winter, and avoid using the mended tire that has been fixed more than once and replace the tire with large abrasion, and different brands as well as the different patterns. There is a big difference between the inside of the tire and the outside of it. In order to keep safe and reduce the wear, owners especially the new car owners should replace the tire for their car regularly.

In addition, a good driving habit is also very important in car maintenance, which is directly connected with the owner. A too fast start, shifted suddenly, emergency braking, driving at a high speed at a poor section and scratched obstacles when stopping your car, etc, all will cause the serious wear of the tire, and thus reduce the service life of your tire. Therefore, a good driving habit is sure to be the most direct and effective way to maintain the tire of your automobile.

So do you know how to maintain your car tire in winter to make it a long time for using? In total, changing a winter tire is necessary! If you are still not sure how to make it, we suggest you first surf the Internet to query the information about the car tire maintenance in winter and try some car diagnostic tools to have a basic checking for your car.
