Inspection and Verification

1. Verify the customer's concern by operating the engine to duplicate the condition.

2. Inspect to determine if any of the following mechanical concerns apply.
3. NOTE: Minor cracks in the V-grooved portion of the drive belt are considered normal and acceptable. If the drive belt has chunks missing from the ribs, a new drive belt should be installed.

Install a new drive belt if any of the following conditions exist:

• rib chunk-out
• severe glazing
• frayed cords or other concerns. Inspect for drive belt cracking/chunking/wear.

4. If the concerns remain after inspection, determine the symptoms and go to the symptom chart. See: Symptom Related Diagnostic Procedures
