How often should a major vehicle maintenance be performed?

[JackLee]

For most private cars, it is reasonable to perform a major maintenance every three years or 60,000 kilometers. If only 30,000 kilometers have been driven within three years, there is no need for a major maintenance, and it can be postponed for a while before going to the 4S shop for servicing. Below are the various items included in a major vehicle maintenance: 1. Oil change: Engine oil needs to be replaced regularly. 2. Throttle body replacement: The throttle body is also a very important component in a car. 3. Spark plug replacement and maintenance: Spark plugs may accumulate carbon deposits or become damaged and require regular servicing. 4. Replacing and adding antifreeze to the radiator: The antifreeze generally needs to be completely replaced every two years or so. After two years, the entire radiator should be thoroughly cleaned, and the antifreeze should be replaced.
