2. Inspect the condition of the timing belt. Replace the belt if you find the following during inspection:
- traces of oil on any surface of the belt;
- traces of wear on the toothed surface, cracks, cuts, folds and separation of the fabric from the rubber;
- cracks, folds, depressions or bulges on the outer surface of the belt;
– fraying or delamination on the end surfaces of the belt.
WARNING: A belt with traces of engine oil on any of its surfaces must be replaced, as oil quickly destroys rubber. The reason for oil getting on the belt (usually due to a leak in the crankshaft and camshaft seals) must be eliminated immediately.
3. Check the belt tension. A correctly tensioned belt should turn 90° with a finger force of 15–20 N (1.5–2 kgf) applied in the middle between the crankshaft and camshaft pulleys. If necessary, adjust the belt tension (see "Replacing the timing belt").
4. Install the parts in the reverse order of removal.
