Review on 🔧 ACDelco Professional 39120 Drive Belt Tensioner Assembly: High-quality with Dual Pulleys by Ashwin Patel

Perfect fit for Jeep Liberty 2003 V6 3.7L. Easy to replace. The only thing to note is that the original tensioner on one of the pulleys is metal and the one on the product image is plastic (black pulleys/pulleys). Unscrewing is difficult as the screw is hidden in the pulley and you need a lot of force to unscrew it. Once you've done that it's easy to swap out and this tensioner comes with its own screw that isn't hidden. Be sure to tighten it as tightly as possible.
