Review on 🔧 Enhanced Performance and Durability: ACDelco Professional 38172 Drive Belt Tensioner Assembly with Pulley by Marco Cervantes

. Two new pulleys and a new alternator were installed at the same time. I rewound the serpentine belt and put a correct size wrench in the slot on this idler to relieve the pressure to get the belt up and over the alternator but the hole has ripped and now I have 2 stress cracks on mine new idler pulley. . I tried as hard to take off the serpentine strap as I did to put it back on. not very happy
