What It Helps Address

• Squealing or chirping accessory belts

• Uneven belt wear from a worn tensioner assembly
• Noise from a failing belt drive system
• Reduced belt stability in high-use Ford engine applications

Installation Notes

Verify the vehicle application by year, make, model, and engine configuration before installation. Inspect the belt, pulleys, and related drive components at the same time, since worn parts in the accessory drive system can shorten the service life of the replacement tensioner. Confirm alignment and belt routing after installation.
