What It Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Belt slip caused by loss of tension or reduced belt grip
• Accessory drive noise during engine operation
• Reduced belt life in demanding fleet service

Installation Notes and Tips

Verify the belt path, rib count, and effective length before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since those conditions can shorten belt life. Confirm the application by matching the Gates K080680HD part number and the vehicle’s accessory drive specifications before service.
