This application featured the very first automatic belt tensioner in the world. Litens Automotive was the original equipment (O.E.) supplier of this tensioner for Ford applications. Since this part was first introduced in 1979, there have been many technology improvements that Litens has now incorporated into this tensioner. The Litens replacement part meets all fit and performance characteristics of the original equipment part but looks different from the original part supplied from 1979-84. The tensioner maintains the O.E. round spring technology as well as a robust steel pulley. The tensioner is supplied with a new installation bolt to ensure proper fit and alignment. Note: The new tensioner has a cast-in locating pin on the engine side of the tensioner. For this pin to fit properly, the location hole on the engine must be slightly enlarged with using a 17/64" drill bit - follow instructions provided. Litens is the world's largest supplier of original equipment (O.E.) power transmission products. At Litens, we design systems that are more efficient, resulting in tangible fuel economy/emissions benefits. Litens holds over 2000 patents and continues to respond to the ever-changing automotive industry by investing heavily in new technology, facilities, and people. 90% of our line is made of products coming from the OE manufacturer, which makes the Litens Tensioning Products portfolio the purest OE tensioning line in the North American aftermarket.

Product Features:

• Designed and engineered by the original equipment part supplier to ensure proper form, fit, and performance.
• Internal "round spring" technology to provide constant belt tension and alignment throughout its service life. The internal damping design provides quiet, smooth, system performance.
• Installation instructions included.
• Heavy Duty Steel Pulley
• Professional Mechanics will change this tensioner in about 20 minutes.
• Accessory drive belts and tensioners are manufactured with similar design life targets. Since belt removal is required to change the tensioner, replacing both will extend the system service life and lower labor costs versus individual replacement.
