Review on Dorman 419 109 Automatic Belt Tensioner by Dean Wildfang

It's just a belt tensioner and it works so I'm not sure how good to say about it. My tensioner on my 5.3 GM started making noise and within 2 days the bearing completely failed, great news with Revain Prime. I ordered it when it started making noise and had it at my house when it was out of order! I've been using it for a few months now, no problems so I hope it lasts a few years!
