Litens Automatic Serpentine Belt Tensioner -Original Equipment Quality

Part No. 999425A Warranty Details  

See if this part fits a specific vehicle.

Check Vehicle Fit

The original tensioner on this Toyota vehicle was a hydraulic design that often exhibited a low frequency noise during early morning cool/cold start-ups. There have been a number of "Fixes" recommended for this problem without much success. The Litens "Fix-Kit" uses various components of the latest tensioner, belt, and alternator pulley technology to offer a permanent solution. The kit consists of a new tensioner with a "mechanical" spring (999418A), a new decoupling alternator OAD pulley (920834A), and a new Goodyear serpentine belt (4060740). As the largest original equipment tensioner supplier to Toyota, Litens understands the drives and offers this solution to resolve this problem.

Product Features:
  • Manufactured by the world's largest Original Equipment supplier of accessory drive tensioners and pulleys.
  • Internal "round spring" technology to provide constant belt tension and alignment throughout its service life.
  • Installation instructions included.
  • Heavy Duty Polymer pulley
  • Professional Mechanics will change this tensioner in about 1 hour.
  • 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.

      A:

      I'm glad to assist, Mike! This Litens Automatic Serpentine Belt Tensioner (Part No. 999425A) does require you to replace the alternator pulley with the decoupling alternator OAD pulley. This replacement can help to eliminate the common failure points of the tensioner system on your 2006 Toyota Corolla S and Corolla LE 1.8L L4. This design is to help address the Technical Service Bulletin EG021-07.

      If your alternator pulley has been replaced with a decoupling pulley, you could purchase only the tensioner (Part No. 999418A) and belt (Dayco Part No. 5060740).
