Product Details

What This Belt Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of proper belt tension due to age-related stretch
• Accessory drive noise from an aging EPDM belt
• Service replacement for vehicles requiring a 6-rib 90.03-inch belt

Installation Notes and Tips

Verify belt routing, rib count, and measured length before installation. Confirm whether your application is for vehicles with or without A/C, rear A/C, or other listed configuration notes, since fitment varies by engine and equipment package. For best results, inspect pulleys, tensioners, and idlers for wear before installing the new belt.
