Replace the timing belt if, upon inspection, you find:

1 - traces of oil on any surface of the belt;

2 - traces of wear of the serrated surface, cracks, undercuts, folds and delamination of the fabric from the rubber;

3 - cracks, folds, depressions or bulges on the outer surface of the belt;

4 - loosening 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 cause of oil getting on the belt (usually this is a violation of the tightness of the crankshaft and camshaft oil seals) must be eliminated immediately.
