Review on 🔧 ACDelco 39162 Drive Belt Tensioner Assembly with Pulley - Professional Grade by Jessie Zdunich

This tensioner has a built in patented damper, no spring to bounce it and make the belt wobble. This turned out to be key for me because whenever my Nissan stopped with the A/C on and in gear the tensioner would bounce like crazy making a horrible rumble. I replaced a new Dayco (#89396) with this part. and the problem disappeared completely and immediately. If you are wondering which one to choose, choose this one. Thats much better. As for the installation. what a pain in the ass!
