What It Helps Address

- Accessory drive belt misalignment at the pulley
- Premature belt wear from poor pulley control
- Noise from a worn automatic belt tensioner assembly
Installation Notes and Tips
Before installation, inspect the serpentine belt, idler pulleys, and accessory pulleys for wear or contamination. Verify pulley alignment and mounting points on the engine before replacing the tensioner. Because this is an accessory drive belt tensioner assembly, correct belt routing and proper torque on the mounting fasteners are important for reliable operation. Confirm application details against the vehicle’s original tensioner dimensions and OE reference numbers before ordering.
