Keep the accessory drive belt properly tensioned and every belt-driven component turning with the SKP Accessory Drive Belt Tensioner Assembly SK89631. It's a direct-fit replacement for the 2011-2020 Ford F-150, 2011-2019 Ford Lobo, 2011-2012 and 2015-2017 Ford Mustang, and 2011-2014 Lincoln Mark LT, and is cataloged for the alternator and water pump position on those applications.

  • Automatic tensioning: Applies spring-loaded pressure to maintain correct tension on the accessory drive belt as it routes over the engine's belt-driven pulleys.
  • Assembly design: Supplied as a complete tensioner assembly for a straightforward replacement of the worn original.
  • Cataloged position: Serves the alternator and water pump belt drive on the listed vehicles.

A worn tensioner can allow belt slippage, squeal, or fluttering as the spring loses its ability to hold tension. If a failed tensioner is the cause of those symptoms, this assembly replaces the original unit.
