Review on Dorman 419-100 Belt Tensioner Assembly - Accessory Drive for Select Models (Black) by Donotello Figueroa

Revainrating 5 out of 5

Fits GMC 2013 Sierra with 4.3L V6

Direct replacement for tensioner on 4.3L V6 2013 Sierra. I had to cut the bushing to allow the stud clamp to engage the bearing inner race, but otherwise it was a straight fit. Works great, time will tell.

Pros
  • Confident
Cons
  • Some problems
