The term "maintenance" is used in this manual to refer to a set of specific operations rather than a single procedure.
If the routine maintenance schedule has been followed accurately since the vehicle was purchased new, and all fluid levels and component wear have been monitored as recommended in this manual, the engine should be in satisfactory operating condition and the need for any additional work should be kept to a minimum.
There may be cases when the engine malfunctions precisely because of a lack of constant maintenance. This is more typical for a used car that has not received regular maintenance. In this situation, in addition to the normal scheduled maintenance, additional work may be required.
If there is a suspicion of general engine wear, then when measuring the compression (see chapter 2B) you can obtain valuable information about the condition of the main elements of the piston group. This information can serve as a basis for making a decision on the scope of work required. If, for example, compression test data indicates significant wear on engine components, the standard maintenance procedures described in this chapter will not improve the situation much, but will waste time and money, but will still require major repairs. Compression measurements should be performed using special equipment and with a certain amount of experience.
A number of measures taken to improve the operation of an engine that has suffered from reduced performance:
First of all:
- Check the level and condition of all engine related operating fluids (subsection 4).
- Clean, inspect and test the battery (subsection 11).
- Inspect the drive belt and adjust its tension (subsection 12).
- Check the condition of all hoses located in the engine compartment (subsection 13).
- Check the condition of the cooling system (subsection 14).
- Check the condition of the air cleaner filter element (subsection 23).
Secondly:
Perform all the above priority operations, adding the following:
- Replace the air filter (subsection 23).
- Replace the spark plugs (subsection 25).
- Check the condition of the ignition system (chapter 5).
- Check the charging system status (chapter 5).
