Put steady automatic pressure back on a serpentine belt with the Dayco Accessory Drive Belt Tensioner Assembly. Its spring-loaded mechanism responds as belt length changes during operation, keeping the drive tensioned without routine manual adjustment. A 74 mm flat pulley and counter-clockwise tensioning define how the Dayco 89441 loads the belt. Those two details matter at installation because the pulley has to contact the correct side of the belt and load it in the direction intended by the accessory drive.
