Review on 🔧 URO Parts 11281433571 Mechanical Belt Tensioner with NTN/NSK Bearing by Telly Roden

It does what it says on the tin. Don't worry, this is indeed the correct AC belt tensioner (with pulley) - part number 11 28 1 433 571 for the BMW E46 (among others). It got stuck in my 323i. However, it turned out that the pulley position was "wrong" compared to the old idler/pulley I was replacing. It wasn't until I poked around the E46Fanatics online forums (very helpful btw!) that I found out that the tab holding the tensioner together (2 holes) needed to come out. After carefully pulling it out with a pair of pliers, the tensioner snapped into place properly. I know noob mistakes! :) Be careful when removing this metal tab as the tension will be released quickly. This could be why the other reviewer's tensioner wasn't positioned correctly. Just for your information.
