  • Visible pulley wear or rough pulley operation
  • Loss of proper accessory drive belt tension
  • Noise from the front accessory drive system

Installation Notes and Tips

Verify belt routing, pulley alignment, and rotation direction before installation. Confirm the vehicle application by year, make, model, and position, since this part is listed for N/A and Main Drive positions depending on the vehicle. Inspect the serpentine belt and adjacent pulleys during service so the new tensioner can operate against a clean, properly routed belt path.

Quality Assurance

Dayco is a recognized name in accessory drive components, and this tensioner assembly is specified with clear pulley and rotation details to support accurate replacement selection. Confirm fitment against the vehicle listing before ordering.
