What do you know about car maintenance?

1, check the lubricating oil level.

Check the lubricating oil level before getting off the bus every time. The engine should be turned off and after a period of time, wait for the lubricating oil to flow back to the oil pan. During inspection, the vehicle must be parked on the ground, then the dipstick should be taken out, wiped with a clean cloth, reinserted and pulled out, and the liquid level should be between MAX and minutes. The difference between the minimum and maximum marks is 1.0 degrees. When the liquid level is lower than MIN, add lubricating oil in time.

2. Engine surface inspection.

Damage to engine sealing surface and oil seal will lead to leakage of lubricating oil. If there is lubricating oil leakage, observe it outside the machine, and immediately eliminate it if found.

3. Check the refrigerant level.

During the normal use of the vehicle, the coolant level should be checked at least once a month. If the engine is hot, check it more often, and check the liquid level at the normal working temperature of the engine. Under the hood. You don't need to open the radiator when checking, just observe the liquid level in the cooling expansion tank, and the normal liquid level should be MAX? Where's Min? Between the marks. When the liquid level is lower than MIN, add coolant in time.

4. Check the smell inside the car.

When driving, if you find an odor in the car, you should stop immediately for inspection. Check the drive belt of the engine and the wires of the car. You can see the general situation from the surface. If there is a smell of gasoline, check whether there is any leakage in the fuel tank and tubing, and immediately eliminate it if found.

5. Supplement and replacement of brake fluid.

The brake fluid reservoir located above the front brake master cylinder is marked with MAX and min. If it is found that the brake fluid is decreasing, it should be added immediately. Brake fluid is toxic and corrosive, and should not be in contact with paint. It has strong hygroscopicity and can absorb moisture in the surrounding air. Therefore, body fluids should be changed every two years. Whether adding or replacing brake fluid, please use the same brake fluid as before. Pay special attention not to mix the brake fluids produced by different manufacturers, because the brake fluids produced by different manufacturers have different chemical compositions. The mixed brake fluid may damage the central parts of the braking system, especially the rubber parts, thus affecting the performance of the automobile.

6. Check the electrolyte level of the battery.

Electrolysis should be maintained during use. If the electrolyte level is too high, the electrolyte will boil and overflow, and if the electrolyte level is too low, the service life of the battery will be shortened. There is a liquid level mark on the battery shell, and the liquid level should be kept between the highest and lowest scale lines or inside the battery. 5MM above the internal partition, when insufficient electrolyte is found, it can only be supplemented with distilled water or special batteries.

7. How to use the starter correctly?

Because the battery is discharged with large current for a long time, it is easy to bend and damage the electrode plate, so the time for using the starter should not be too long, not more than 5 seconds at a time.

8. Keep the radiator and water jacket clean.

Keeping the radiator clean inside and outside is an important condition to improve the heat dissipation performance. There is mud outside the radiator, which will affect the flow of air volume and make the coolant temperature too high, so it should be cleaned in time.
