Serpentine Belt Tensioner: 1 Piece

from

$334.99
Litens was the Original Equipment (O.E.) supplier of this part and offers this “O.E. Exact” part for the aftermarket. This popular tensioner designed for Toyota w/3.5L vehicles, looks, fits, and performs like the original part being replaced. “O.E. Exact” – Original Equipment manufacturers prohibits the use of their part number or logo on parts sold to other customers. Therefore, the Litens aftermarket part may have minor cosmetic differences but still be exact in performance and design. Like the original design, this tensioner maintains a molded lift feature in the arm, and the heavy duty steel pulley. Choosing The Correct Replacement Part: Both the original equipment and Litens aftermarket tensioner use a round spring versus a flat spring and are marked “Made in Canada”. 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:
  • Manufactured 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 Pin Included to Assist in Installation.
  • Heavy Duty Steel Pulley
  • Includes lift-lug feature for ease of installation.
  • Due to the fact that belts and tensioners have similar Original Equipment “design life targets”, it is often a best practice to replace the belt tensioner when replacing a worn or broken belt.
  • Belt removal is required to change the tensioner. Therefore, doing both together will extend accessory drive life and lower overall labor versus performing these services separately. Installation instructions included.
