1. Belt
There are two reasons for the noise of the belt when starting the car engine or driving the car: one is that the belt has not been adjusted for a long time, which can be adjusted in time after discovery. Another reason is that the belt is aging and needs to be replaced with a new belt.
2. Air filter
Dirty or blocked air filter will directly lead to increased fuel consumption and poor operation of the engine. Check the air filter regularly every day. If it is found that there is less dust and the blockage is not serious, it can be blown out with high-pressure air from the inside to the outside and continue to use. The dirty air filter should be replaced in time.
3. Gasoline filter
If you find that the oil supply is not smooth, you should check whether the gasoline filter is blocked in time. If you find that it is blocked, you should replace it in time.
4. Engine coolant level
After waiting for the engine to cool down, check that the liquid level of the coolant should be between the full level and the low level. If not, please add distilled water, purified water or refrigerant immediately. The added liquid level should not exceed the full level. If the coolant decreases rapidly in a short time, check whether there is leakage or go to a special automobile maintenance shop for inspection.
5. Tyre
The tire pressure is directly related to the safety performance of the tire. Too high or too low tire pressure will cause bad results. The tire pressure should be lower when the temperature is high in summer and sufficient when the temperature is low in winter. In addition, check the cracking of the tire. If there are potential safety hazards, replace the tire in time. When selecting a new tire, it should be consistent with the original tire model.
