Which items need to be maintained by the car after long-distance driving? After long-distance trekking, especially after driving in bad road conditions, for those small cars that are only suitable for urban roads, the loss of their vehicle condition will be very great. It is recommended that the owner of the vehicle take the car to the maintenance station for a secondary maintenance. After understanding the importance of maintenance, what are the maintenance items to be done?
1. Add oil and water to the vehicle to check if the oil is sufficient and if the oil quality is good. Contents include engine oil, coolant, glass water, etc. If the liquid level is insufficient, it is added. The oil is bad and needs to be replaced.
2. Prevent leakage and check the power assembly and transmission system for oil leakage. There are several major components (such as engine, gearbox, rear axle, etc.) with or without leakage of oil.
3. Reinforced chassis Although each car is delivered from the factory, its chassis has undergone anti-rust treatment, and some have even been treated with double-sided galvanization or double-sided anti-rust treatment. However, in terms of professional and technical personnel, those prices are within 200,000 yuan. For domestic cars, if the chassis is limited to running on a smooth city road, checking the 10,000-kilometer chassis is not a big problem. However, if some mountain roads or bad roads are gone, mud and other dirt can easily attach to the chassis. On the chassis, even some gravels that constantly hit the chassis will peel off the protective layer of the chassis, and the possibility that the chassis will be rusted will increase. Therefore, even if the vehicle is traveling only a few thousand kilometers, chassis inspection is still necessary.
The test contents include whether the transmission parts and suspension parts are loose or damaged (such as drive shafts, axle shafts, half shaft boots, suspensions, shock absorbers, ball heads) and chassis corrosion inspection.
4. Tire inspection Hidden tires are the only parts of the car that touch the ground, so the chance of injury is also high. The owner can check the tire for obvious injuries or scars. If there is a visible scar on the sidewall, it is best to replace the tire because the sidewalls are thin and the pressure is limited. The chance of a puncture is greatly increased.
The maintenance should first check the tire pressure, wear conditions, whether the nuts loose or fall off, remove the inserts and nails and other sharp objects such as nails. If there is a deviation or a pendulum in driving, you need to re-do four-wheel alignment or balancing.
5, the brake system includes brake pads, brake tubing, brake master cylinder, sub-pumps, hand brakes and so on.
6, circuit inspection, including lights, instrumentation instructions are normal.
7. Cleaning of engine oil roads Some of the scenic spots are backward, and there may not be high-grade gasoline supply. If low-grade gasoline or low-quality gasoline is used, on the one hand, the engine generates knock and noise; on the other hand, the exhaust pipe catalyst, that is, the three-way catalytic converter, is likely to fail, and then the exhaust gas is unqualified, and part of it will block the exhaust pipe. Due to poor exhaust, the engine is weak and increases fuel consumption. Severe damage to the internal parts of the engine, such as the top of the piston, etc.
In the above situation, the engine can be cleaned and maintained.
