Detailed Description

Common Issues This Part Can Address

• Belt squeal caused by weak or inconsistent tension
• Visible belt flutter or vibration at idle
• Uneven accessory drive belt wear
• Noisy operation from a worn tensioner assembly
• Loss of proper belt tension after spring fatigue or component wear

Installation Notes and Tips

Verify the existing tensioner design before ordering. 1993 Ford E-350 Econoline, E-350 Econoline Club Wagon, F-250, and F-350 applications require the enclosed spring design, while 1994 applications listed here are for vehicles without a damper on the tensioner. Confirm belt routing and inspect the accessory drive belt, pulleys, and mounting surfaces during replacement.
