An automatic belt tensioner keeps the serpentine belt at the right tension as it stretches and as accessory loads change. A weak tensioner lets the belt slip and chirp. This Gates DriveAlign tensioner is built to replace the original unit.

Gates 39677 DriveAlign Belt Tensioner Features:

• Maintains Correct Serpentine Belt Tension
