What items need to be maintained after long-distance driving? After long-distance trekking, especially after driving through bad road conditions, for those cars that are only suitable for urban roads, the loss of the car condition will be great. It is recommended that the owner send the car to the repair station for a comprehensive maintenance. After understanding the importance of maintenance, what maintenance items should be done?
Add oil and water
Check whether the oil and water of the whole vehicle are sufficient and whether the oil quality is good. The content includes engine oil, coolant, glass water, etc. If the liquid level is insufficient, add it, and replace the oil if it is of poor quality.
Prevent oil leakage
Check the powertrain and transmission system for oil leakage. The content mainly includes whether there is oil leakage in several major components (such as engine, gearbox, rear axle, etc.).
Reinforced chassis
Although the chassis of each car is anti-rust treatment before leaving the factory, and some even go through double-sided galvanizing or double-sided anti-rust treatment, from the perspective of professional and technical personnel, those domestic cars whose prices are less than 200,000 yuan If the chassis is only limited to driving on smooth urban roads, it will not be a big problem to check the chassis once 10,000 kilometers, but if you walk some mountain roads or rotten roads, then mud and other dirt can easily adhere to the chassis, even Some gravel that keeps hitting the chassis will also peel off the protective layer of the chassis, which increases the possibility of the chassis being rusted. Therefore, even if the vehicle only travels a few thousand kilometers, the chassis inspection is still necessary.
The inspection content includes whether each transmission component, suspension component is loose or damaged (such as transmission shaft, half shaft, half shaft dust cover, suspension, shock absorber, ball joint) and chassis corrosion inspection.
Tyre check hidden danger
The tire is the main part of the car in contact with the ground, so the risk of injury is also higher. The owner can check the tires for obvious injuries and scratches. If there are obvious scars on the sidewall, it is best to replace the tire, because the sidewall is thin and the pressure is limited, and the chance of a puncture will be greatly increased.
During maintenance, first check the tire pressure and wear condition, whether the nut is loose or fall off, and remove the embedded objects and iron nails between the twin tires or on the tread. If there is deviation or swing when driving, you need to perform four-wheel alignment or dynamic balance again.
Brake system
Including brake pads, brake tubing, brake master cylinder, sub-cylinder, hand brake, etc.
circuit inspection
Including whether the lights and instrument instructions are normal.
Clean the engine oil circuit
Some scenic spots are underdeveloped, and there may not necessarily be a high-grade gasoline supply. If you use low-grade gasoline or inferior gasoline, on the one hand, the engine will produce knocking and noise; on the other hand, it will easily cause the exhaust pipe catalyst, namely the three-way catalytic converter, to fail, resulting in unqualified exhaust emissions and sometimes blocking the exhaust pipe. , Due to poor exhaust, the engine will be weak and increase fuel consumption. Seriously, it will damage the internal parts of the engine, such as the top of the piston.
