Keep the serpentine belt properly tensioned and every engine accessory turning with the Dayco Accessory Drive Belt Tensioner Assembly 89698. It drops in as a direct-fit replacement for the 2011-2014 Ford F-150 (V8-5.0L), applying spring load to the belt so the alternator, power steering, water pump, and A/C compressor stay driven without slip or squeal.

  • Serpentine belt design: built to run on a serpentine accessory-drive belt.
  • Single flat pulley: one flat-profile pulley measuring 70 mm in diameter and 26 mm wide.
  • Counterclockwise rotation: the pulley turns counterclockwise as cataloged.
  • Made in the United States.

A worn tensioner can show up as belt squeal or chirp, a fluttering or vibrating belt, or a rattle from the accessory drive. If a failed tensioner is the cause of those signs, this assembly replaces it. Inspect the belt and the other pulleys at the same time and replace as needed.
