What This Part Helps Address

• Belt squeal caused by weak or inconsistent tension
• Serpentine belt flutter or visible misalignment
• Premature belt wear from poor pulley control
• Accessory drive noise related to a worn tensioner
• Loss of stable belt tension on high-mileage GM applications

Installation Notes and Tips

Verify engine and belt routing before installation, since fitment is limited to serpentine applications listed in the vehicle data. Inspect the belt, idler pulleys, and related accessory drive components at the same time so the new tensioner assembly can operate against a properly serviced belt path. Confirm the part number SK89253 against the existing tensioner and vehicle application before ordering.
