What is the automotive maintenance process?

[Quinn]

Automotive maintenance process mainly includes: 1. Engine oil level check. When the vehicle is on a level surface, if the oil level is between the F and L marks, it is normal. If it is below L, add the specified type of engine oil, ensuring the oil level does not exceed F. 2. Battery maintenance check. Mainly check if the battery is secure. If the electrolyte level is near the lower line between the upper and lower lines, replenish the electrolyte promptly. Ensure the battery's positive and negative cables have good contact and keep the battery clean and dry. 3. Air filter inspection. A dirty air filter can cause poor engine performance, increased fuel consumption, and engine damage. When inspecting the air filter, if minimal dust and light clogging are found, clean it with high-pressure air from the inside out for continued use. A heavily dirty air filter should be replaced immediately. 4. Spark plug inspection. A normal spark plug has intact insulation ceramic with no leakage. The spark plug gap should be 0.8±0.0mm, producing a strong blue spark during discharge. If abnormalities are found, adjust the gap or replace the spark plug. 5. Fuel filter inspection. If fuel supply is poor, check if the fuel filter is clogged. Replace if obstructed by debris. 6. Tire inspection. Check tire pressure monthly at normal temperature. If below the standard, replenish promptly. Pressure should not be too high or too low, as it affects driving safety. Replace tires immediately if cracks are found. When selecting tires, ensure the model is consistent.
