Installation Notes and Tips
Verify pulley groove count, belt type, and mounting dimensions before installation. Inspect the accessory drive belt, idler pulleys, and related components for wear at the same time, since a worn belt can shorten the service life of a new tensioner. Confirm the belt routing matches the vehicle’s accessory drive layout before final tightening.
