Review on Dorman 419-016 Automatic Belt Tensioner: Enhanced Efficiency for Optimal Belt Performance by Sam Doucette

Revainrating 5 out of 5

Dorman Belt Tensioner

I installed this tensioner on a Jeep Wrangler 4.0L in about 2 minutes. The square puller hole was at a slightly different angle than the OEM tensioner, making it easier to change the belt later.

Pros
  • Engine Parts
Cons
  • poorly thought out
