Part No. 999410A Warranty Details  

See if this part fits a specific vehicle.

Check Vehicle Fit

This Litens belt tensioner is manufactured by the original equipment tensioner supplier and meets all form, fit, and performance characteristics of the original equipment part (with the exception of not having the car manufacturer's logo or part number applied to the part). As with the original equipment part, this replacement tensioner is manufactured in Germany for Mercedes-Benz. The tensioner maintains the O.E. round spring technology as well as the internal damping design specified for this application. There is a lift feature molded into the arm on this tensioner for ease of belt removal & replacement.

Product Features:
  • Manufactured by the original equipment part supplier to insure 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 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.
