Review on High-Quality Belt Tensioner Pulley Assembly for Jeep Grand Cherokee/Wagoneer & Dodge Ram 1500 - 1993-2001 - Direct Replacement with 38116 53010158AB by Shaun Robinson

Easy install with a 15mm wrench and a little sweat. This is the belt tensioner and pulley. You may only need to buy the tensioner, but since mine was 20 years old I figured I could spend a few bucks more and replace both. There are videos on the internet showing how to do it. I installed this on my 2001 Ram 1500 5.2L 2wd truck. Don't forget to buy a new serpentine belt.
