Do you know how to the scientific use of fuel additives

How to use the fuel additive to work better? Many intend to use additives owners are still hesitant, because we are not consistent with the view of additives, additives to buy more trouble. There is another kind of circumstance, a lot of people who have buy good fuel additive products but do not know how to use, also do not know how to use the OBD Diagnostic Tool check, that will also affect the fuel additive role play. Here we ask the repair shop of professional technicians explain to us the proper use of fuel additives.

For a long time the car must use, if don't want to continuous use can also between a month with more than three times, if intervals recommended dose it slightly larger, truly effective removal of carbon deposition, improve the fuel environment. The use of the most economical method is used for the first time the way plus three times in a row, that is a new car in the first three tank, every time, in accordance with the purchase of the directions specify the percentage of adding additives. After three times, run about 3000 km to 3000 km (is different according to different road conditions and oil), again plus three times in a row, repeat this cycle is more appropriate, you can use a Launch X431 V Pro or Launch X431 Diagun III tools to check the performance of the car, you can see the obvious transformation.

For used cars, during the initial period, the additive will engine oil system in the gum or sediment washing down, it will lead to clogged filters and oil hole, this time to deal with the oil system, a cleaning and maintenance, and then follow the new car Add mode to continue to use, so purifying effect is more ideal.

Adding proportion is 1: 1000, 50ml bottles of additives can be with 50 liters of fuel; in addition, add should as the condition, models and and vehicle vehicle condition is good for the first time for about 3 bottles; condition decreased, underpowered vehicles need continuous use more than 5 bottles until the condition improved. Then choose the next box to add one or 1000 kilometers every time to add. If the engine is in good condition, it can be used to reduce the proportion of the mixture.

To remind you, as the market chaos, consumers should choose a well-known brand certified, select Do not freeloaders, should pay attention to product quality, the company strength, service assurance and brand reputation, should choose to clean the engine and hydraulic system and other conservation tools Comprehensive features well-known brands. We recommend car stick with fuel additives, keeping nozzle without clogging, no coke combustion exhaust standards; with higher mileage cars, to select super-concentrated high-quality products, and gradually clean the oil and the engine, to clean, lubricate, by Horsepower easy start effect, you can also use Autel MaxiDas DS708 or Xtool PS2 tool to check car, you will reconsider whether or not to use fuel additives.

Modified spark plug to improve vehicle power

Improve the car power is great for the performance of the car, for the use of better fuel, oil and other oil additives, plus all kinds of components, system modifications, OBD Diagnostic Tool equipment. Likewise, which takes a lot of money, which is a lot for the household expenses. How simple and economical  modification to enhance car power?

Now many people adapted to fuel-efficient as the starting point of simple modification, strive to fuel consumption in the same premise, reached in modified certain extent improve the actual effect of the dynamic performance of the vehicle. For the average power conversion has mature technology, need to use Launch X431 V Pro or Launch X431 IV GX4 Master tools. Usually around in spark plugs, wire, high flow style. In high-performance spark plugs and wire as the most affordable modification.

Common spark plug on the market there are ordinary spark plug, iridium, platinum spark plug, etc.. Ordinary spark plug electrode materials are generally made of Ni Mn alloy, iridium spark plug which belong to the rare metal iridium material. Relatively high melting point metal iridium, high temperature resistance, high pressure resistance, quality is good, so iridium spark plugs can a stronger and more stable spark.

From the price point of view, the ordinary spark plug per only 5 yuan to 10 yuan, the Japanese production of iridium spark plug every 80 yuan to 100 yuan. Generally speaking, the original factory assembly of domestic ordinary spark plug best every 20000 km to replace a, and better performance of iridium spark plugs can use the 60000 km to 8 million km, or even 10 million kilometers. So from the price performance than point of view, it is recommended that consumers buy iridium spark plugs, a small amount of money to spend, you can make the vehicle dynamic performance is more excellent, more cost-effective. Use Autel MaxiDas DS708 or XTOOL PS90 tool to replace the spark plug, the working hours for the general to tens of dollars to a hundred dollars.

Good driving habits to prolong the service life of the battery

On the basis of the daily maintenance, but also to develop good driving habits, as follows:

1, do not frequent starting vehicles
Do not exceed 5S at the start of the engine, if the first start fails, don't rush to start again. From the working principle of the car, at this time, a continuous starting motor will certainly cause the battery over discharge and damage. So the time interval should be more than 15s. If the 3 time is still a failure, use the Auto Diagnostic Tool to find out the reasons, troubleshooting.

2, under flameout state Do not use electrical equipment inside the car for a long time
This is often encountered in the daily use of cars, but also easy to overlook the problem. For example, sit in the car to rest, et al, to fuel many drivers turn off the engine and sat in the car listening to the radio or watch DVDs, so do the purpose of fuel is reached, but deeply hurt your battery. Correct method of use is stalled in a state of continuous listening to the radio to no more than 30 min, at the same time do not recommend use equipment such as car DVD in stall condition.

3, under flameout state try not to use external power supplies
External power equipment such as dust suction machine, a portable air pump, avoid by all means not to use in vehicle flameout state. As the power of these devices is bigger, use in a stall condition for a long time can easily consume battery power, and thus affect the normal starting of the vehicle. Can be used to Launch X431 V Pro or Launch X431 IV GX4 tool test battery working condition.

4, parking must turn off the lights and the car with electrical appliances
When parking stall, forget to turn off the lights, which is a lot of new car owners easy to make mistakes. After a night of consumption of the battery, at any time may not have electricity, can not start the car. Try not to use CD, cigarette lighter and other electrical equipment in the vehicle did not start. In the course of driving, the vehicle is also less used variety of automotive electrical appliances.

5, first close the air before flameout
Most of the owners are not accustomed to air-conditioning or allow air conditioning with the vehicle starting automatically after the start, which will cause the vehicle ignition switch every time, the air conditioning system will automatically start work, the consequences are directly lead to the vehicle instantaneous power load is too high, a long time will cause a certain loss of battery. Correct habits should be, every time to reach the destination, the first switch off the A/C keys, let the wind blow for a few minutes, to ensure that the air conditioning system internal drying, reducing the breeding of bacteria. Then turn off the air conditioner before the stall. Every time after restarting a car, air conditioning.

In short, general automotive battery life in 2 years or so, if the use of Autel MaxiDas DS708 or Xtool PS2 tools to maintain proper maintenance, up to 3-4 years. We understand its function, on the basis of proper maintenance, and can develop good driving habits.

Auto Body jitter causes and solutions

Body slight jitter is the situation many owners often encountered. If the owners start the vehicle, if we find the body slightly shaking, then there is likely to mean that the vehicle under three kinds of condition:

If the driving car process, found the body there is a slight jitter or offsets, generally is a tire caused by failure. First may be tire balance condition, need the owner to do a four-wheel positioning and dynamic balance as soon as possible, if the vehicle is not running deviation do the tire dynamic balance, and then use the Auto Diagnostic Tool to check tire dynamic balance.

Another condition is more serious, may be because the steel ring caused by deformation, which requires owners to professional repair shop to check. This situation generally occurs in the use of a longer life of the vehicle body. General motors to replace the new tires, new rims must be used followed by the Launch X431 PAD or Launch X431 Creader VIII tool to check the tire balance, otherwise the weight average steering wheel is not easy to happen dithering phenomenon. Body jitter on driving comfort and manipulation of the judge will make a difference.

The third situation caused by shaft deformation imbalance, general this kind of situation in the chassis more car collision.

If there is a car body jitter, which is aimed at the vehicle equipped with manual transmission, the performance is: in the beginning and slowly lift the clutch pedal process, the vehicle has a jitter. This is due to a clutch three piece suit (flywheel, clutch plate and pressure plate) the irregular wear, in which one or a few pieces to produce deflection caused by, in the bonding process, clutch disc can not be smoothly joined, but a joint, a little and release of the engine power is just beginning to transfer, and suddenly slipped, the vehicle performance is similar jumps is feeling. Replace the damaged parts of the clutch in three pieces, and then use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the performance of the car.

Car battery maintenance guide

Maintenance staff said, in the car maintenance, the battery maintenance is also important. Some vehicle owners and maintenance personnel for battery maintenance do not pay attention, do not understand, did not develop good habits and cause the battery life shortened, and even damage to other electrical equipment. General battery available 2-3 years, but if you use unreasonable, 3-4 months, it may be replaced, you can check the battery through the OBD Diagnostic Tool, real-time control of battery performance.

How to determine the battery needs to be charged? Can not rely on the brightness of the headlights or sound intensity to determine the working state of the battery, you need to use the Launch X431 V+ Pro3 or Launch X431 V Pro tool to check, if the brightness of the lights dimmed, to the time when the battery has entered a state of loss, the car must not be launched. In order to ensure the normal work of the battery, the owner is best used in the battery every half an hour, start the engine to charge a battery.

Today, the car on the electric equipment more and more, such as the car after the car to use the electric power of the equipment before the headlights, tail lights, reading lights and radio or CD, so, the owner in the use of these electric equipment, as far as possible not to let the battery overload work. If flameout, no need special should first turn off the headlights, and then stall, in the night started when the car should also start the reopen after the headlight, to minimize the damage to the battery.

If you let the battery in the engine stopped state, it must prevent the battery power loss, if the loss of power is likely to cause damage to the battery. Now there is a kind of technology can repair the damaged battery, adopts pulse charging technology which will activate battery electrolyte, still can continue to use. But if losing electricity, battery will be scrapped in advance.

A 4S shop maintenance staff had said, according to use Autel MaxiDas DS708 or Xtool PS2 tool to check the battery experience, in a good car battery case, open the headlights, reading lights, radios, capacity 35Ah battery operating time is about three hours, while the capacity of 45Ah battery operating time can be a little longer, between 3-4 hours. The higher the volume of the radio or CD, the greater the power, so the battery power usage time, also consider this issue. In addition, the battery of the new and old also affect the duration of the duration of the power. If users do not install some of the original electrical appliances, such as the bass, etc., will cause the excessive use of batteries. He warned the owner, if the battery is old, working time is best not more than 2 hours.

How to clean EFI engine fuel injection system

EFI engine is currently on the vehicle use a very wide range of equipment, compared with the conventional carbureted fuel system, EFI engine fuel supply system, not only complex, but also parts with precision. When using Auto Diagnostic Tool maintenance necessary to pay special attention.

During cleaning maintenance, some parts can not be disassembled and dismantled, some parts assembly requirement is high, which makes gasoline injection system than the carburetor type vehicles are more vulnerable to the dangers of gasoline in the colloid, sediment, the cleaning is very complex.

The engine fuel supply system, the air inlet and exhaust system are clean and have a decisive influence on the driving performance of the vehicle. Due to the impact with the environment and fuel quality injectors, intake manifold, intake and exhaust valves and the combustion chamber is easy to produce gelatinous precipitates, etc., affect the normal fuel supply, cause by fuel injection quantity control is not accurate, the fuel spray is bad, the oil pressure regulation failure, which causes the engine idle speed instability, the acceleration bad, knock, lack of fire, fuel consumption, exhaust emissions exceed the failure phenomenon. These faults can be using the Launch X-431 PAD or Launch X431 Creader VIII tool checked out.

In order to clean the oil supply system to solve the problem from the inside, they usually avoid demolition clean way. Vehicle cleaning jobs by special Autel MaxiDas DS708 or Autel Maxidiag Elite MD701 tools and equipment and cleaning agents, under certain pressure and flow control, intake manifold, fuel injectors, intake and exhaust valves and combustion chamber thorough cleaning to restore the normal operation of the fuel system, to ensure good driving performance of the car.

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.

Honda Accord ABS Light abnormal breakdown maintenance

There are a lot of friends in the Honda Accord sedan, the engine is F23A1 type, equipped with variable valve timing system (VTEC), after traveling 31,000 kilometers, ABS lamp lights up abnormal, need to use OBD Diagnostic Tool.

Honda Accord sedan ABS system consists of a solenoid valve safety relays, pump relay, wheel speed sensors, hydraulic pressure regulator (pump solenoid valve and a sliding piston assembly), accumulator, pressure switches, ABS lights and ABS computer components.

The car is equipped with self-diagnostic system, remove the right side of the glove box, to find self-diagnosis seat blue 2-hole outlet, using the Launch X431 GDS or Launch X431 V+ Pro3 tool to check. The ignition switch is pulled to the ON position, ABS lights flashing fault code is 10, indicating that non-stop operation of the electric pump the brake fluid. But boot up ABS lights, the pump does not turn. According to the principle and circuit diagram analysis ABS system, the cause of this fault code may be caused by insufficient pressure or pressure switch can not be closed.

Checked for leaks, ABS tank is not short of oil. So to find the pressure switch wire (yellow) to the computer at the office and the hydraulic actuator Ground Test. Ignition lock ON state, ABS lights, start the engine, ABS lamp. ABS pump operation, after the 10s ABS lights, pump stopped. Then the yellow line Ground, ABS lamp goes out, after re-grounding 5s, ABS pump stops, so repeat 1min, ABS lights were never bright. Measured with a multimeter pressure switch grounding line is normal, open the hydraulic actuator on the pressure switch cover, using a flat-blade screwdriver move microswitch direct pressure, measured with a multimeter two terminals blocked, replace micro switch on the same type of ABS, loading retest car, ABS light is off, everything is normal.

Because of the pressure switch on the micro switch is damaged, start the engine, ABS pump operation, produce high pressure brake fluid to the accumulator, solenoid valve, pressure switch, even boost, but at this time the pressure switch can not be closed, Autel MaxiDas DS708 or Autel MaxiDiag Pro MD801 tool detected ABS pump work for a certain period of time, the hydraulic pressure is still not up to the pressure, can not use the ABS system and shut down the ABS pump, ABS lights lit. Replace the same model ABS micro switch, ABS lights go out, everything is normal.

How to replace the fuel filter

Before trying to repair the car you have to always wear goggles, when necessary, still need to wear the PPE personal protective equipment, such as latex gloves or closed type shoes. Keep in mind that petrol is highly combustible, and when you are ready to deal with the fuel system to ensure that there is a fire extinguisher and Auto Diagnostic Tool, to prohibit smoking, to ensure that the fire away from the car or fuel tank, must be careful when working.

Steps:
1. To park the car on a solid plane.

2. Reduce pressure fuel system (fuel injection systems operate at very high pressure environment, the need to reduce pressure), follow these steps:
(A). Loosen the valve cover to reduce the fuel system pressure
(B). Remove the fuel pump relay or fuse (according to your owner's manual operation)

3. Start the engine until you run out of the pipeline gas engine stop.

4. To find the position of the fuel filter, which is generally below the engine or the fuel tank. If necessary, you can use the jack to lift the car, and from the fuel filter out of the oil pipeline.

Note: The old car carburetor, the oil pipe is hose with spring. The new injection type engine, the oil pipeline and the clip together, or the quick lock connector, require special Launch X431 PAD or Launch X431 V+ Pro3 tools to remove.

5. Remove the mounting bolts of the fuel filter, fuel filter can be removed then.

6. Compare whether the new fuel filter and removed type is consistent, confirmed after installing a new fuel filter, pay attention to ensure its leading to the engine, can filter retaining bolt installation confirmation.

7. connected to the pipeline and install the fuel pump fuse.

8. Re connecting the battery box, and you can lower the car after it is finished.

9. Start the engine and check for fuel leaks.

Note: Due to the lack of fuel, the engine may not start immediately, but with the fuel pressure increase the engine will start.

10. The actual driving cars, using Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check whether the engine is weak.

Audi A8 airbag use guide

Audi A8 car airbags as a standard configuration. For this system fault repair, need to master the structure of the system, working principle, and the Auto Diagnostic Tool correct test method. Here combined with the specific failure systematically to introduce.

1, Audi A8 airbag system structure and function
Audi A8 uses a multi point electronic sensor type airbag system, mainly composed of the following parts: control unit, side impact sensor, airbag, contact unit and safety belt tensioning device, etc.

Control unit, which includes 1 electronic acceleration receivers (i.e., frontal impact sensor), microprocessor, 1 mechanical acceleration receivers (for insurance), diagnostic systems (with memory), 1 accumulator and 1 crash recorder. The main function of the control unit is to receive the signal of the collision sensor, safety belt switch, monitor the status of the implementation of the system, the final issued instructions to the detonation of the airbag, the engine stopped working, connected to the alarm switch and lights up the fault lamp, and has self check, system monitoring and storage of fault information, crash records and other functions.

2, testing methods and precautions during maintenance
Audi A8 sedans airbag system has self-check function; Every time in the car when the system will detect the introspection; Once the system has a fault is detected, the instrument of red AIR BAG light will be bright. If the indicator light does not shine on when the ignition switch is turned on, or when the light is on, the system is in trouble, the system is in trouble. Fault diagnosis of the system can only be diagnosed by V.A.G1551, A. G1552 V., AS5051 V or other Launch X431 PAD or Launch X431 GDS diagnostic apparatus.

In addition, the system and the Audi car other electronic control systems, by using a dedicated Autel MaxiDas DS708 or Autel Maxidiag Elite MD702 diagnostic instrument that can be queried, troubleshooting part number and system software version of its system, the implementation of the final element, clear DTCs, read data blocks and coding and other functions to the control unit, the system's address code is 15.

No matter what kind of car airbag, it is only as a safety device, and can not put it as an absolute guarantee of adult life. So, in daily driving, we must pay more attention to the safety of driving, be sure to use the safety belt device.

The same car, why fuel consumption high when you drive

Some car owners may very strange, the same a car, even for the same car, let others open, fuel consumption fell by half! Why do you have a higher fuel consumption than others?

1, bad habits: rapid acceleration
Personal driving habits have a relatively large impact on gasoline consumption, due to the mechanical design of a variety of styles, you need to run for a period of time will enter a relatively good state. During start-up, hard acceleration, braking and sometimes a good opportunity to reflect performance of the car. Driving this surge will make your fuel consumption, by OBD Diagnostic Tool test data show, it is 2-3 times the normal driving! Best driving speed is preferably maintained at 60-80km / h. And observe the road conditions in advance, it can be done with the throttle control for speed!

2, traffic reasons
This may not have much relationship and driving, but also fuel efficient route choices very important part, sometimes from far away, in the choice of route, try to choose not congested routes, from as short as possible! Only in this way can save more gasoline!

3, trunk mat put too much items
Vehicles carrying too heavy items, will make the fuel consumption is higher than the normal driving fuel consumption of about 2%! It may not seem like a lot, with a long time Many a little make a mickle., so many items, the count is not a small sum of money. So don't put things in the car!

4, pay attention to tire pressure
Some car owners may think that hot summer weather, the tire will Rezhanglengsu, so slightly deflating the tires! Suitable tire pressure for fuel consumption and life of tire is very meaningful! Through the Launch X431 IV GX4 Master or Launch X431 V Pro tool test, as long as there is a tire less hit 40Kpa of gas, the life of the tire is reduced by 10000 kilometers, an increase of 3%! If the tire pressure is reduced by 30%, to 40km/h to calculate the words, the fuel consumption will increase by 5%-10%! Therefore, adjust the tire pressure is more important for fuel-efficient terms!

5, engine technology
When buying a car should be aware that some young owners obsessed with appearance of the car, ignoring the fuel consumption and other factors, recommendations in the car before first practical Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect the car engine, engine technology for fuel-efficient advantage whether performance excellence. This is also very important!

Car sideslip need to timely maintenance

Rainy day driving, the vehicle sideslip possibility increases, in addition to good driving habits and skills, but also the brake and the state of the tire good is also the key to safe driving. Automobile brake system is the most dual vacuum assisted hydraulic brake. Brake fluid transfer braking force which has strong water absorption. If water into the brake fluid in the braking process, the high temperature friction will produce water vapor. The gas is compressible, the brake fluid is compressed, it will cause brake failure or even failure, so after a rainy day, the need to use the OBD Diagnostic Tool to check vehicle braking systems.

Solution: Some brake fluid absorption water more serious vehicle, in the brake fluid oil on the cover can see water droplets. So in the maintenance must use the Launch X431 PAD or Launch X431 V Pro tool to check the brake fluid, to ensure the life safety of occupants. Once found the car brake fluid suction serious, should be sent to the professional repair shop in addition to water.

Also, before the arrival of the rainy season, if the vehicle tire wear, tire wear, must be replaced. someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important, regular use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect automobile tire pressure.

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.

Auto cooling system maintenance tips

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.

Oil tank filled full oil has four big taboo

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.

Nano fuel additives basic knowledge

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.

How to maintain the car automatic transmission

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.

Air filter and car battery maintenance guide

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.

Lubricating oil color black need to be replaced immediately?

Many drivers see lubricant color black, they think oil quality has been a serious deterioration, and replace it, resulting in waste. Normally, car oil at just replaced, color is golden yellow, are generally will added clean dispersant, the purpose is to wash the adhesion and black carbon deposition film on the piston down and dispersed in oil, reduce engine generate high temperature deposits, so the use of lubricants colors tend to darken after a period of time, but this time the oil does not deteriorate, the use of oil is serious deterioration, needs to be replaced by the Auto Diagnostic Tool can determine whether the need to replace, is not observed the oil color black, concludes that need to be replaced lubricant.

Under normal circumstances, regardless of any brand of lubricating, its life cycle can be maintained at more than 5,000 km, to the 8000 km -10 000 kilometers need to replace oil. Only when the long-term bad driving habits, such as frequent Jicha, refueling too fast, the speed at 3000 rpm or more frequently, oil change intervals will advance.

After a period of time, engine oil the color will gradually darken, why lubricant color will change to black?
First, the fuel in the olefin content, sulfur content is high (gasoline engine is easy to form sludge, diesel engines easy to form smoke stains), easy to make the engine oil black, and thus fuel quality is the source of oil black.

Second, the different structure and working conditions of the engine, it is easy to make gasoline engine oil sludge generated, form smoke stains incomplete combustion of diesel engine, thus lubricant turning black, you can use a Launch X431 V Pro or Launch X431 Diagun III tools to check these phenomena.

Third, In order to overcome the fuel and mechanically induced results, lubricating oil to adding dispersant to prevent sludge or smoke stains on the cylinder formation deposited in the film or the body, the higher the quality of the oil, dispersed better, but oil is volatile black, so high quality oil, than the poor oil variable black faster.

Fourth, Oil color black produced sludge is related to launch a pilot time overly high temperature operation, and not to clean the engine when the car in the oil and oil bottom, associated with the filterability of oil filter.

Engine oil replacement time, premature cause lubricating oil waste, too late will increase engine wear and shorten engine life and maintenance cycle, so you need to use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the engine. The deterioration degree of lubricant has relationship with the performance of automobile, repair technology, driving level, road and weather condition, lubricant quality, etc, uniform regulations drain intervals sometimes not entirely realistic. If after a period of use of lubricants appear dimmed color, white, indicating filling oil mixed with water, which emulsion occurs. The basic properties of lubricants has been completely lost, the engine cooling system and combustion system for leaks, should not continue to use.

Oil filter working principle and type

Oil filter is one of the four filters, the other three filters were air filter, air conditioning filter and fuel filter, oil filter is filtering effect of oil impurities to protect the engine does not suffer wear, You can use OBD Diagnostic Tool to check whether the engine is wearing.

Oil filters filter principle can be divided into three categories: mechanical separation, centrifugation and magnetic attraction.

Mechanical separation according to its function and form can be divided into pure mechanical separation, aerial separation and adsorption separation, purely mechanical separation of common mesh filter, on the surface of the filter material has a certain size of holes, the oil of solid particles, the size is greater than the holes will be blocked on the filter material appearance, aerial separation is first attached to one or several small particles size is greater than their cavity the filter material on the inner wall of the cavity size smaller, then the particle because not pile up in the past, the formation of aerial phenomena, the filtering particle size smaller than the cavity size. Since the majority of particles in the oil is irregular, so overhead phenomenon is easy to form. And colloidal substances in the oil, use the Launch X431 GDS or Launch X431 V Pro tools inspection found that often adhesion on the surface or the inner wall of the cavity, the filter material is the adsorption separation.

The centrifugal separation is a rotor that causes the oil to rotate through a high speed, and the impurity in the oil is thrown to the inner wall of the rotor and thus separated from the oil.

Magnetic adsorption is the permanent magnet will be oil in the iron particle adsorption over. Don't let them in oil cycle back and forth, mechanical damage.

On filter classification, generally have the following methods:
1. According to the filter structure form classification: is there a wound rotor, scraping plate, etc.

2. By filtration fineness Classification: surface filtration and depth filtration.

3. After filtering way classification: surface filter and depth.

4. Arranged in the lubrication system by way of classification: a full-flow and bypass type.

Generally recommended 5000km replacement of oil filter, specific according to actual Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool inspection data to decide.
