Engine Drive Belt Inspection
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Mirror cracks in belt rib are normal. They are the result of reverse bending around a backside pulley. Do not replace belts for minor cracks.
Belts that have chunking longer than 5 mm (13/16 in.) in one or more places should be replaced.
Belts should also be replaced if cord breakage or fabric separation is observed.
