    Comments about CARQUEST by Dayco Idler Pulley:

    My wife was stuck in gridlock traffic less than .5 miles yards from our house, and noticed the "snap" sound. She limped her 2001 Mercedes e320 to the driveway. I flipped open the hood and noticed the original idler pulley snapped in half on the back side which also shredded the drive belt. This was easy to replace and then install a new drive belt in less than 30 minutes. Car back running again. The original and replacement part is plastic and has lasted 13 years, but still cant believe Mercedes puts a plastic idler pulley on their cars. If it was aluminum, it would never need replacing. Oh wait, then they wouldnt have parts to sell. Hmmmmm....

        This Idler/Tension pulley was the wrong part - needed No Slack Belt Tensioner. Returned with no problems for correct part.

        I don't know what Mercedes is thinking with a pulley made of plastic??? My pulley shattered into pieces during afternoon commute which disabled the car, so I had to get a replacement ASAP. I found this to be the same as OEM, and stocked locally. I'm not sure if there is a metal option out there, but if there is and I had time to wait, I would order one.

          Direct replacement for OEM pulley. Beaing design appeared to be superior to OEM pulley that was replaced.
