      Part No. 999034A


      This genuine Litens tensioner is manufactured and designed by Litens, the world's largest manufacturer of belt tensioners. To address shortcomings and common failure points of the original tensioner, Litens has released this new and improved design. A 20% increase in tension resultes in less noise and belt slip. The main tensioner pivot has been greatly improved to prevent binding frequently experienced with the orginal part, and and a high speed bearing has been implemented to provide long life and reliability.While the appearance is slightly different from the original equipment part, the Litens part meets, and in most cases exceeds, GM's original form, fit, and function specifications. Note: This drive has experienced issues due to the A/C system. GM issued a Technical Service Bulletin (TSB #01139B/C) suggesting replacement of the A/C compressor to resolve belt jumps and flutter issues). Litens includes a Tech-Tip concerning this issue with the tensioner.

      Product Features:

      • Manufactured by Litens, the largest original equipment tensioner & pulley supplier in the world, to ensure proper form, fit, and performance.
      • Internal "round spring" technology to provide constant belt tension and alignment throughout its service life.
      • Heavy Duty Steel Pulley with close tolerance ball bearing pocket and Electro-deposited coating for superior corrosion resistance
      • Professional Mechanics will change this tensioner in approx. 20 minutes.
      • 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.
