What maintenance should be done after driving 40,000 kilometers?

[Harvey]

Maintenance items that should be done after driving 40,000 kilometers include: 1. Changing the engine oil and oil filter, which are required for every maintenance; 2. Checking the air filter and cabin air filter to see if they need replacement. If they are not severely dirty, they can be cleaned and reused, but if heavily soiled, they must be replaced promptly; 3. Fuel filter; 4. Thoroughly inspecting various fluids; 5. Checking the battery; 6. Replacing spark plugs; 7. Inspecting brake pads and tires. Generally, these components may not need replacement at 40,000 kilometers, but if any abnormalities are found, replacement is necessary. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing.
