Review on ACDelco 38158 Professional Automatic Tensioner by Alex Foley

Needed to replace the Lower AC Belt Tensioner (38259) on our 2003 speedo after 129,000. I figured that while this one was going, maybe not long before this one was going too. Glad I exchanged it. Comparing the tension between new and old was the difference between day and night. The ACDelco 38158 professional automatic belt tensioner and pulley assembly fit perfectly and were easy to swap out. This is a high quality ACDelco part, not a counterfeit.
