Technical Details and Specifications

The Dayco 89483 tensioner assembly is specifically designed for serpentine belt systems that require a clockwise directional tensioner. It includes one pulley with a diameter of 74 mm and a width of 39.25 mm, featuring a flat pulley surface to ensure proper belt alignment and reduce slippage.

Installation Notes and Tips

When installing the Dayco 89483 tensioner assembly, ensure the serpentine belt is routed correctly according to the vehicle’s belt diagram. The clockwise rotation direction of the tensioner must be observed to avoid improper tensioning. Use appropriate tools to relieve tension from the old belt and carefully position the new tensioner assembly. Verify pulley alignment and belt tension after installation to ensure optimal performance.
