Drive Belt Inspection - 3.0L: Notes
WARNING: This page is about a different car, the 2005 Mazda B3000. However, it is still accessible from the selected car via links, so may be relevant.
- Verify the customer's concern by operating the engine to duplicate the condition.
- Inspect to determine if any of the following mechanical concerns apply:MECHANICAL PARTS SPECIFICATION
Mechanical - Drive belt cracking/chunking/wear.
- Drive belt noise or squeal.
- Pulley misalignment or excessive pulley runout.
- Inspect for drive belt cracking/chunking/wear.
- If the concerns remain after inspection, determine the symptoms and see SYMPTOM TROUBLESHOOTING CHART - DRIVE BELT
.
Under severe operating conditions (high temperature, low humidity), drive belt rib cracking can occur at less than 96,000 km (60,000 miles). Drive belt rib cracking (cracks across grooves):
- is not a reason for concern.
- has no detrimental effect on drive belt performance.
Cracks parallel to grooves are acceptable.
The drive belt is still perfectly functional until rib chunking occurs. Drive belt chunking is where the rubber material actually chunks out between the cracks. The drive belt should be replaced if chunking occurs.
- If the concern(s) remains after inspection, determine the symptoms and see SYMPTOM TROUBLESHOOTING CHART - DRIVE BELT .
