[Automobile World Maintenance] First, you must first understand which basic components of the next car are composed. After understanding the main structure, we roughly divided the car into a youth car, a middle-aged car and an old car. This is the same as people, and the parts that are replaced and replaced at different times are different. Youth car (0-4 years old) In general, the first two years of a car is the peak of life, as long as the routine maintenance, there will be basically no problem. The main maintenance tasks include: changing the oil, checking the steering device, checking the brake pads, and replacing the four filters. ◆ Four filters (oil, air, air conditioner and fuel filter collectively): The most common periodic maintenance parts. (5000-1.5 million km). ◆ Wiper blade: Ensure the driving line is clear and ensure driving safety. (1 year) ◆ Brake Pad: It is recommended to check the brake pad wear condition every time you have a small maintenance. (3-4 million km, 2 years) ◆ Fuel pump: The fuel is sucked out from the fuel tank, pressurized and sent to the fuel supply pipe, and cooperates with the fuel pressure regulator to establish a certain fuel pressure. (3-4 million km, 2 years) ◆ Shock Absorber: The damper is part of the suspension system. If the damper spring is no longer elastic, it will shake very much at high speeds, especially in rainy weather. . (5-6 million km, 3-4 years) ◆ Spark plug: (6-8 million km, 3-4 years) ◆ Brake fluid /antifreeze: (usually in 6-7 million kilometers, 3-4 years ◆ Battery: 3-4 years old middle-aged car (4-7 years old) For more than 4 years, the analogy is like “people are in middle age”, many parts will be loose, especially after Long-distance high-speed bumpy vehicles. Coupled with the natural aging of various rubber tubes in the car and so on. For a vehicle that travels to middle age, in addition to routine maintenance, pay special attention to the maintenance of the following components: ◆ Timing system: The timing system is the core component of the engine transmission, including the timing belt and related trains. . Usually, when the vehicle is driving 70,000 to 100,000 kilometers, it is necessary to check or replace the timing system. If the vehicle suddenly runs halfway, the sudden break of the belt may cause engine damage, which is too expensive. ◆ Rubber tube: During the age of the car, problems such as black oil leakage and water leakage often occur. This is due to the natural aging of the rubber tube. ◆ Coolant reservoir: For vehicles of about five years, the tank may be corroded by chemicals inside, so some of the tanks of the car begin to leak. Older car (7-10 years old) Due to the limitation of automobile life, in China, cars generally retire after 10 years. If properly maintained, the car can still complete its mission as scheduled. In addition, most auto-shifted cars should also be repaired at this time. Of course, the chassis system should also be carefully checked for repairs. In general, this stage is based on inspection and replacement. ◆ Water tank: 7 years, 10-12 million kilometers ◆ Check automatic transmission, electronic throttle replacement, three-way catalytic converter replacement: 7 years, 100,000 km ◆ Clutch assembly: including clutch pressure plate, clutch driven plate and Separate the bearings. 12-15 million kilometers need to be replaced. Other components such as oil seals in powertrain and transmission systems, crankshaft pulleys in vibration damping systems, etc., can also be replaced depending on the degree of failure.
