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.

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.

Automotive filter maintenance guide

Automotive filter is a device used to filter impurities. In the car the main air filters, oil filters and fuel filters, known as the "three filter." Filters used to filter impurities, filter has a great influence on the main effect of other components, in use, must be regularly use Auto Diagnostic Tool maintenance and replacement.

First, the air filter
Car engines are very sophisticated parts, tiny impurities will damage the engine. Therefore, the air before entering the cylinder, must first go through the air filter cleaner, in order to enter the cylinder. The air filter has relations with the life of the engine.

Currently, the car engine is used widely in the filter paper, it has a low mass, low cost, easy to replace, high efficiency filtration, general cleaning once traveling 5000 kilometers. Clean the filter should be removed gently tapping the end face, use compressed air to blow from inside to outside , do not wash with gasoline or water. Traveling 25,000 kilometers must replace the air filter.

Second, the oil filter
Most car engines using spin-on oil filter, this filter is not disposable filter unpick and wash, when changing the oil must replace the oil filter, otherwise it will affect the oil quality. Replace the oil and oil filter cycle, generally is 5000 km. Pay particular attention when changing the oil filter, but also pay attention to the choice of oil, you can use Launch X431 GDS or Launch X431 V Pro tools to detect engine performance.

Third, the fuel filter
At present, most of the engine is a one-time non-washable jacket-style paper filter, fuel filter replacement cycle is generally 10,000 km. When replacing the filter, the filter has to pay attention to the arrow mark, in the replacement, do not installed anti. Recommend the replacement cycle of fuel filter should be according to its structure, properties and USES of varies.

Most car manufacturers on the external filter recommended normal maintenance and replacement cycle for 50000 km. If you are unsure, please use Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS501 tool to view. In addition, when the filter hose appears the dust, oil and other dirt, causing the hose aging or cracks, the need for timely replacement hose.
