Product Description

Litens® 999034A Accessory Drive Belt Tensioner Assembly

Serpentine Belt Tensioner

Accessory Drive Tensioner

Automatic Belt Tensioner

This genuine Litens tensioner is manufactured and designed by Litens, the worlds 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, GMs 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.

Manufactured by Litens, the largest original equipment tensioner and 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.

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.

Installation instructions included.
