If you follow the suggested maintenance program correctly, and check fluid levels frequently and inspect components that are likely to wear, your new car's engine will remain in good working order and the need for additional maintenance will be minimal.
If regular maintenance is not performed, the engine may develop problems, which is even more likely if you buy a used car. In such cases, additional work will need to be done.
If engine wear is suspected, check the compression (see Section 2), which will give you valuable information about the performance of its major components and help determine the extent of the required repairs. If, for example, the test showed serious engine wear, the normal maintenance described in this Section will only be a waste of time and money, since it will not improve the engine performance unless an extensive overhaul has been performed beforehand (see Section 2).
The following series of actions consists of operations most often necessary to improve engine performance:
Primary actions
- a) Clean, inspect and test the battery (See. "Weekly checks").
- b) Check all engine related fluids (See. "Weekly checks").
- c) Replace the spark plugs (Chapters 30 and 37).
- d) Inspect the ignition system components (Chapter 31).
- e) Inspect the high-voltage ignition wiring (Chapter 31).
- f) Check the condition of the air filter, replace if necessary (Chapter 27).
- g) Check the condition of all hoses, inspect them for signs of leaks (Chapter 4).
