  Tensioner, Tensioner Timing Belt

• Description:

  This genuine Ford tensioner is the timing belt tensioner for the 3.0L Power Stroke turbo diesel V6 used in the 2018 through 2021 F-150. Unlike most modern Ford gasoline engines, the 3.0L Power Stroke drives its camshafts with a belt, and this tensioner maintains correct belt tension so valve timing stays accurate and the belt cannot skip a tooth or slap under load. Over time the tensioner bearing can wear, the mechanism can lose its ability to hold tension, or the pulley can become noisy, any of which threatens belt security. Because this is an interference diesel engine, a loose, jumped, or failed belt can allow piston to valve contact and catastrophic internal damage, so the tensioner is a critical wear item that Ford specifies for replacement as part of scheduled timing belt service. Buyers typically need this part when performing preventive timing belt maintenance at the recommended interval, chasing a tensioner or belt area noise, or completing a front-of-engine repair on the 3.0L Power Stroke. Ford lists it under the catalog name Tensioner - Timing Belt. It should always be installed together with a fresh belt and related idlers and guides, with the engine correctly timed to the factory marks and every fastener torqued to specification. Confirm your F-150 carries the 3.0L Power Stroke diesel before ordering, as gasoline F-150 engines do not use this belt system. As a genuine Ford component it meets the original tension, bearing, and durability specification for reliable service.

• Applications: 3.0L DIESEL.
