Review on Enhanced Performance ACDelco Professional Automatic Tensioner – Model 38159 by Shane Loredo

Finally managed to replace the AC tensioner (and belt) on my 2001 Suburban, no more creaking! It's an OEM part so no surprises on installation, check youtube for how to replace it, I did it in a parking lot without lifting the Suburban, there's plenty of room although the bolts are a bit tight. The part I received was marked with the production date "19". I think the part I took off the truck was the original "01" so it lasted 18 years, no wonder it squeaked!
