Review on 🔧 ACDelco GM Original Equipment 89017309 Drive Belt Tensioner: Efficient Performance and Reliability by Joseph Anderson

This is a suitable replacement for the stock tensioner that has worn out on my 00 S10 4.3. Most of the part is metal with the inscription "Made in Canada". The black wheel is made of plastic, as is the standard tensioner. I would have preferred a metal wheel but it does the job. It seems to work fine, doesn't creak or click like an old worn one. Let's see how long this lasts.
