Maintenance method of automobile aging stage

If the car is used for the first two years, it usually only needs routine maintenance. The main maintenance needs include: changing the oil, checking the steering gear, checking and replacing the brake pads, and replacing the four filters.

Four filters (gasoline filter, engine oil, grille, air conditioning grille): This is the most common regular maintenance accessories. (5000-65438+500,000 km)

Wiper blade: ensure clear driving sight and safe driving. (1 year)

Brake pads: It is recommended to check the wear of brake pads every time for minor maintenance. (30,000-40,000 kilometers, 2 years)

Fuel pump: the fuel is sucked out of the fuel tank, pressurized and delivered to the oil supply pipe, which cooperates with the fuel pressure regulator to establish a certain fuel pressure. (30,000-40,000 kilometers, 2 years)

Battery: (3-4 years)

Shock absorber: The shock absorber is a part of the suspension system. If the spring of the shock absorber is no longer elastic, it will shake badly when driving at high speed, especially in rainy days. (50,000-60,000 kilometers, 3-4 years)

Spark plug: 60,000-80,000 km. (3-4 years)

Brake fluid/antifreeze: generally 60,000-70,000 km. (within 3-4 years)

Middle-aged car (4-7 years old)

Vehicles over 4 years old, just like "people reach middle age", will have many problems such as loose parts, coupled with the natural aging of some rubber pipes in the car. In addition to routine maintenance, cars in this period should also specially check the maintenance of the following components ~

Coolant storage tank: For vehicles about five years old, the water tank may be corroded by chemicals inside, so some vehicles' water tanks begin to leak.

Timing system: Timing system is the core component of engine transmission, including timing belt and related gear train. Usually, when the vehicle travels 70,000 to 654.38+10,000 kilometers, the timing system should be checked or replaced. If the timing belt suddenly breaks in the middle, it may damage the engine and the price is too high.

Rubber tube: At this age, problems such as black oil and water leakage often occur. This is caused by natural aging of rubber pipes.

Old car (7- 10 years old)

In China, cars should be scrapped in 10. If properly maintained, most cars can still finish their tasks on schedule healthily. Generally, every part of a car of this age is seriously aging. In particular, it is necessary to check the automatic gearbox, replace the electronic throttle, and replace the three-way catalyst, and check it frequently to ensure driving safety ~

Water tank: 7 years,10-120,000 km.

Check the automatic gearbox and replace the electronic throttle and three-way catalytic converter: 7 years, 65,438+10,000 kilometers.

Clutch assembly: including clutch pressure plate, clutch driven plate and release bearing. 12-150,000 km needs to be replaced.

Others: For example, oil seals in power system and gearbox system, crankshaft pulley in vibration damping system and other components can also be replaced according to the degree of failure.
