Long-distance running car maintenance Raiders

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 the vehicle condition will be very great. It is recommended that the owner of the vehicle deliver the car to the maintenance station for a full maintenance. After understanding the importance of maintenance, what are the maintenance items to be done?

Add oil

Whether the full vehicle oil and water inspection is sufficient and 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.

Prevent oil leakage

Check the powertrain and transmission system for oil leakage. There are several major components (such as engine, transmission, rear axle, etc.) with or without leakage of oil.

Reinforced chassis

Although each car is delivered with a rust-proof chassis, some are even treated with double-sided galvanizing or double-sided rust-proofing. However, in terms of professional and technical personnel, domestic cars with a price of less than 200,000 yuan are If the chassis is limited to running on a smooth city road, checking the 10,000 km of the chassis will not cause serious problems. However, if some mountain roads or bad roads are gone, mud and other dirt can easily adhere to the chassis, even Some gravels that constantly hit the chassis will also 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 transmission shafts, axle shafts, half shaft boots, suspensions, shock absorbers, ball heads) and chassis corrosion inspection.

Tire inspection hidden

Tires are the main components 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 better to replace the tire because the sidewalls are thinner 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 tires on the tire or 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.

Brake system

Including brake pads, brake tubing, brake master cylinder, cylinder, handbrake and so on.

Circuit inspection

Including light, meter indication is normal.

Clean engine oil circuit

Some scenic spots are backward, and there is not necessarily a high-standard gas supply. If low-grade petrol or low-quality gasoline is used, on the one hand, the engine will produce knocking and noise; on the other hand, the exhaust pipe catalyst, that is, the three-way catalytic converter will easily fail, and then the exhaust emissions will be unqualified, and sometimes the exhaust pipe will be blocked. Due to poor exhaust, the engine will exhibit fatigue and increase fuel consumption. Severe damage to the internal parts of the engine, such as the top of the piston, etc.
