What It Helps Address

• Belt slack caused by a worn or weak tensioner

• Uneven serpentine belt tracking in the main drive system
• Belt vibration that can affect accessory drive performance
• Loss of proper belt tension on the listed Cadillac CTS and Chevrolet Camaro applications

Installation Notes and Tips

Verify pulley direction, groove count, and main drive placement before installation. Inspect the serpentine belt, idler pulleys, and related accessory drive components for wear at the same time, since a new tensioner works best with a belt in good condition. Confirm vehicle fitment by year, make, model, and position before ordering.
