Automatic transmission car maintenance knowledge

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

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

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

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

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

Paper air filter installation and maintenance guide

Through Auto Diagnostic Tool checking data found paper air filter has the following advantages:
1) Filter efficiency up to 99.5% (oil bath air filter 98%), dust transmittance of only 0.1% -0.3%;
2) structure compact, can be installed in any orientation, not by vehicle parts layout constraints;
3) when maintenance is not consume fuel , but also save a lot of cotton yarn, blankets and metal materials and other substances;
4) the quality of small, low cost.

Based on the above advantages, car engines use air filter paper core is becoming more common. The key of good paper air filter is to keep its sealing performance, prevent unfiltered air from bypass entering the engine cylinder.

Paper air filter installation and maintenance guide
1. During installation, air filter and the engine intake pipe between rubber pipe coupling or direct coupling must be tight and reliable, to prevent leakage, the filter must be installed at both ends of the rubber gasket surface; fixed wing air filter housing nuts can not be tightened too much, so as not to crush paper filter.

2. In use, the air filter to prevent rain water paper, because once a large amount of water adsorbed paper, will greatly increase the intake resistance, shorten the service life.

3. Some vehicle engine is equipped with Tornado air filter, paper filter ends of the plastic cover is shroud cast blades rotating air, Launch X431 IV GX4 Master or Launch X431 V+ Pro3 tool data showed that: 80% of the dust separated by centrifugal force and collected in collection Dust arms, to dust paper filter for inhalation of dust was 20%, the total efficiency is about 99.7%.

4. During maintenance, paper filter never use oil cleaning, otherwise the paper filter will be failure, but also easily lead to accidents. When maintenance, use only the vibration method, soft brush division (which folds down to brush) or compressed air cleaning methods remove the attachment surface of the filter paper dust, dirt. Part of the strainer, should be promptly removed the dust parts, pipes, etc. of leaves and cyclone dust. Even if every time meticulously maintained, the paper filter can not completely restore the original performance, the intake resistance will increase, therefore, generally when the paper filter is required when the 4th maintenance, it should be replaced with a new air filter. If the paper filter rupture, perforation or unglued paper and cover other issues, should be replaced immediately.

Air filter is the air enters the engine from the first hurdle, automobile engine is very precise parts, the tiny impurities will damage the engine. Therefore, in the air into the cylinder before, must first go through the fine filtration of air filter, can enter the cylinder. You can use the Autel Maxidiag Elite MD701 or Autel MaxiTPMS TS601 tool regularly to check the engine, and the air filter status is related to the engine's life.

How to buy automotive air conditioning filter and refrigerant

Some owners for air-conditioning system maintenance, how to choose the right accessories to do air conditioning maintenance will encounter many problems. Due to the owners of vehicles are not familiar with, and don't want to use Auto Diagnostic Tool to check, so here we give you a introduction to buy these accessories:

1. How to buy air filters?
Air filter: quality of original brand quality long-term air conditioning filter with respect to the poor quality of ordinary Deputy plant air filter, in the service life and impurity filtration efficiency to far wins a chip. Can guarantee the higher impurity filtration efficiency and extend the maintenance cycle.

2. Refrigerant How to choose?
Refrigerant: Pure brand R134a environmental refrigerant, it can ensure 2--3 years of life. Currently on the market of the refrigerant uneven, some good and some bad, media have exposed automotive air conditioning refrigerant sample test pass rate is currently less than 10%. If you use of counterfeit refrigerant in a short time can refrigeration, but long-term use, light will produce refrigerant leakage, resulting in automotive air conditioning and refrigeration effect is not good, will lead to serious damage to the air conditioning compressor, if use Launch X431 V Pro or Launch X431 IV GX4 tool to check in advance, can quickly check out the fault. So when buying refrigerant, must pay attention to choose the high quality brand pure refrigerant.

Buy air filters, refrigerant and air conditioning cleaning agent must pay attention to product quality, quality air filters, air conditioning refrigerant and air-conditioning cleaning agent can play a very good protection, increase of air conditioning refrigeration effect, kill in air conditioning mold and bacteria, eliminate odor, recovery and the freshness of the air inside the car, but inferior air filter, refrigerant and air conditioning cleaning agent not only can not achieve the effect, but will damage parts of the air conditioning system, use the Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS601 tools to check parts of the air conditioning system performance, inferior products will reduce the service life of the air conditioner and the human health will be affected.

How to buy high-quality car brake oil

Speaking of automotive brake systems, we naturally think of the importance of the brake pads, it has been a normal reaction to contact with safety, another key element for automobile brake system -- brake oil , people don't really care, but don't know it is a key link in automobile braking systems, the relationship between the owners of personal safety. According to Transportation Department data shows that If all people use the brake oil, every year to reduce the 10% traffic accident, how to buy high-quality brake oil, need to use Auto Diagnostic Tool.

Currently on the market the brake oil is divided into three types: type of alcohol, mineral oil and synthetic type. Alcohol and mineral oil has been eliminated, market of brake oil for the synthesis of type, common brake oil have DOT3, DOT4, DOT5, most of the cars used are DOT4 brake oil.

How to buy brake oil?
1, different types and different brands of brake oil do not mix, due to the different synthetic ingredients, mixing brake fluid can cause brake oil index declined, If you use the Launch Creader VII or Launch X431 Creader VIII tool, it's easy to see the change.

2, the normal running of the vehicle, If the brake suddenly light or suddenly heavy, to the timely replacement of brake oil, before replacement, first with alcohol will brake system clean.

3, when the brake oil sucked moisture or impurities, should be replaced or the filter, otherwise it will cause the brake pressure insufficiency, the effect of the brake. There are some places the weather is wet, this is particularly important.

4. Vehicle braking wandering, to the braking system to conduct a comprehensive inspection. If discover wheel cylinder cup expansion is too large, brake oil quality there could be a problem. At this time should choose quality good brake fluid replacement, replace the leather bow at the same time.

Clean, high-quality brake oil is the basic of good work condition of safety and brake system. Vehicle on 40,000 km or brake oil continuously used for more than two years, then the brake oil needs to be replaced. When choosing the brake oil to note that if the use of inferior brake oil, brake pump will rot burning Pusey, use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the brake pump to see whether the work is stable, will also have an impact on the brake effect, so if the brake oil lack, it is best to specialized shops to buy the original car brake oil, the original brake oil use effect is very good, can also prolong the service life of the system of brake.

How to replace the air filter

The automobile engine is very precision components, a very small impurities will damage the engine. Therefore, in the air into the cylinder before, must first go through the air filter, can enter the cylinder, air filter is safe valve of the engine, air filter is good or bad relationship with the life of the engine, you can use the OBD Diagnostic Tool to check whether the engine is damaged.

Air filter disassembling method
Replace the air filter is the most simple, many cars do not even need any Launch X431 GDS or Launch X431 V Pro tool, replace the air filter is very simple. the replacement, first loosen the hoop, then release around spring clips on the air filter housing, The air filter cover counterclockwise turn at an angle, the cover can be removed, if that valve chamber cover the ventilation duct obstruction, it can be plugged in. Remove the air filter, put the new air filter installed, then all the removed parts put back in situ.

Replace the air filter should be noted:
Many models of air filter, not only different models are not the same, is the same in different models of the product shape is also different. If it yourself replacement, the best first removed the old pieces, compare to buy. Quality air filter paper very dense, and the texture, color uniformity, paper and plastic edges are not hair stubble, support the filter of barbed wire is also very neat, smell, not pungent smell, otherwise there may be counterfeit or made of recycled materials shoddy products.

When the car with mileage of air filter maintenance mileage interval specified, or the air filter clogging indicator alarm, must be used Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to clean the air filter. In general road conditions, the car driving 7500-8000km must be on the air filter cleaning and maintenance.

How to identify oil filter

The oil filter is used to filter the oil dust, metal particles, sediments and suspended particles and other impurities, reduce impurities wear and tear on parts and protect the engine and other equipment. The quality of the oil filter is we have to consider, how to use the Auto Diagnostic Tool to identify oil filter, choice genuine oil filter is our common concern.

Fakes: Filter surface print is not clear or fuzzy, print the paint on the surface of inferior, thin. No bypass valve, once the filter clogging, the engine will not get enough lubrication oil. After flameout did not inhibit the oil return function, cold start of the engine wear will be greater. The gasket sealing material, high temperature and high pressure may cause oil leakage, and even cause a fire. The filter material, to a predetermined filtering effect. Metal oil net coarsely, difficult to guarantee the oil amount of energetic.

Hazard: The counterfeit oil filter pump not only affect the normal lubrication of the engine, and because of shoddy, the interface of the main oil may have Mifengbuyan conditions, resulting in a binding machine oil filter and cylinder face jump out, the result will cause oil leakage, poor engine cooling failure. You can use the Launch X431 V Pro or Launch X431 GDS tool to check these failures.

Genuine: filter surface factory standard font printed clearly, printing paint with good texture, pure white. With internal bypass valve, ensure that any state has a sufficient amount of oil supply. Inhibition of reflux design complex, ensure the filter has the next time you start to oil, reduce the wear of the cold start (all are factory filter this bag is equipped with protection function). Before leaving the factory, a lubricating grease at the interface, the sealing gasket material, rubber material according to the rules. The filter oil specially developed, moderate density, ensure the filter oil filter core. The metal in the form of standard oil through the network, to ensure the oil throughput.

Oil filter is the most commonly used cars consumables, thousands of kilometers will be replaced together with oil. Although this inexpensive small parts, but in the course of normal operation of the engine, but plays an important role. If it's out the problem will make fuel consumption increase, increased engine wear and tear; Severe then let the engine scrapped, So, you need to regularly use Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS601 tool to check the car's performance.

How to prevent car spontaneous combustion

In summer, the car ignition incidents continue to occur, in fact, the majority of vehicles spontaneous combustion are to be expected. Automotive body noise, a coke burnt taste, smoke is likely to be the precursor of spontaneous combustion. In case of spontaneous combustion, the car personnel should immediately leave the car, you can use the OBD Diagnostic Tool to detect vehicle performance, professional advice, occur in hot weather, the owner of car maintenance should pay attention to the following points:

First, check the oil. We usually find that a lot of cars have symptoms of chassis oil spill , in the hot season, which is likely to be the cause of spontaneous combustion. And the spontaneous combustion accident at ordinary times is also for oil. Hence the need for frequent use Launch X431 V Pro or Launch X431 Creader VIII tool to view the car, if the engine oil spills, oil spills chassis tubing signs of aging or broken it should go to a professional repair shop or 4S shop maintenance.

Second, check the circuit. More than three years of car especially modified car headlights, modified car stereo should be comprehensive examination. Car circuit fire occupy a considerable proportion of spontaneous combustion events. Engine, ignition coil, high temperature, high voltage ignition wire insulation softening, aging, dehiscence, high-voltage ignition easy breakdown of the insulating layer, it is easy to produce high-voltage leakage, leading to spontaneous combustion.

Third, after the car stopped immediately shut down the engine , to develop good driving habits. The hot season, the ground temperature is higher, when parked idling and others, the maximum temperature of the exhaust pipe under the car, even higher than 800 ℃. If there is a parking ground hay, paint, or other flammable items, for a long time under the baking will be on fire, and burn the car.

Fourth, Clean up the car of inflammable and explosive materials. The male driver of friends like lighters on the center console, in the hot season, this habit will become very dangerous. Another perfume contains more alcohol, and very easy to fire. Now a lot of automotive interior materials generally do not have fire resistance in case of fire, the fire spread easily.

Summer is the high incidence of car ignition, the car ignition, generally due to a short circuit electrical wiring or inside the vehicle flammable materials. To avoid spontaneous combustion to reduce the chance of your car, regular maintenance regularly, but every car with at least one Autel MaxiTPMS TS601 or Autel MaxiTPMS TS401 tools, check the car function.
