Drive Belt: Initial Inspection and Diagnostic Overview
Under severe operating conditions (high temperatures, low humidity), drive belt rib cracking can occur at less than 96,000 km (60,000 miles). Drive belt
rib cracking across backing is not a reason for concern and has no detrimental effect on belt performance. Cracks parallel to backing are not acceptable.
Drive belt "chunking" occurs when the rubber material actually chunks out between the cracks. Replace the drive belt if chunking occurs.
