Litens – Accessory Drive Belt Tensioner – Original Equipment Quality (Part No.999034A)

Accessory Drive Belt Tensioner - Original Equipment Quality

from

$56.99
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 results in less noise and belt slip. The main tensioner pivot has been greatly improved to prevent binding frequently experienced with the original part, 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. Litens is the world’s largest supplier of original equipment (O.E.) power transmission products.
