I found out today that the aux belt tensioner slightly rubs my aux belt. A while ago I replaced the pulley on my alternator since the original plastic one that was one there broke. I replaced it with a metal one I found on here. Could it be possible that there's a slight size difference in the pulley which causes the tensioner to slightly be off and therefore rub? The part of the tensioner that rubs is the very bottom part of the spring. See pics in the topic below, mine looks exactly like that.
Hey, I've noticed a bit of rubbing between the tensioner spring and the aux belt. I was wondering what may have caused this and what I can do to keep them apart. Clio 172 53 plate. Here are some pictures, any help would be greatly appreciated.
