General Information
Worn or loose drive belts may cause engine overheating or loss of alternator power. Excessive tension, or too little tension on the belt may result in excessive and premature belt wear or accessory bearing failure. Serpentine belts are retained by a belt tensioner that requires no tension adjustment. Replace the drive belt if any conditions described below are found. To inspect a belt, gently twist it to view the belt sidewalls and bottom.
Important: For EPDM rubber drive belts, do not rely on cracking as an indicator of belt wear. EPDM rubber drive belts resist cracking better than Neoprene belts. A better indicator of wear on EPDM belts is material loss.
