Review on ACDelco 38177 Professional Automatic Tensioner by John Tarnowski

This automotive tensioner is top-notch! After trying this product, I can confidently say that it is an excellent addition to any car's belt system... The installation was a breeze and the tension it provides is spot on. My car feels much more efficient and performs better since I have added this pulley. The only negative is that it`s a little pricey, but the quality easily justifies the cost..
