Maintain steady belt tension as engine speed, load, and temperature change with the Dayco Accessory Drive Belt Tensioner Assembly. Its spring-loaded design automatically follows normal belt movement, so the accessory drive does not depend on repeated manual adjustment as the belt works and ages. A 74 mm flat pulley on the Dayco 89933 applies that tension to the back side of the belt in the required counterclockwise direction. Matching the original mounting position and travel lets the tensioner keep the belt loaded through normal operating movement.
