Is an accessory drive that slaps, rattles or wears its ribs unevenly due for a replacement tensioner? The Dayco Belt Tensioner is the spring-loaded arm that keeps a serpentine loop tight as the engine runs and the accessories load and unload. The Dayco 89485 replaces the worn pivot, spring and pulley so the arm can follow changes in belt load again. Even tension spreads the pull across every rib and quiets the front of the engine at idle.
