Could this be the noise in my car?

I've been a kind of chirping in my car. It's not really a squeal tho. I believe I might have gotten it down to this pulley.

I checked the other pulleys and none have play but this one has the slightest punt of play to it.

The belt seems fine the ribs are still in really good shape.

So what is the pulley called? (Hard to search for something when u don't know which it is lol). Could this be the noise? Can I just tighten the bolt or am I gonna have to buy a new one? I heard some ppl for/against belt dressing.

It's the one to the left of the alternator btw

It is a belt idler pulley I believe, if I were you I'd tighten the bolt, see how it does but if it continues looks like you'll have to buy a new one

#1, NO BELT DRESSING!! If it's making noise, there is a reason for it. Fix it.

#2, Since it's not squealing all the time, I'd suspect it's just the bearing in the pulley. Not likely something you could easily replace or re-pack, so a new pulley should do the trick. The good news is, they are really cheap, and easy to replace.

That's not a problem, same thing will happen if you wash use engine degreaser and wash it off. As long as it just last you shouldn't worry about it.

Try pouring some water on each pulley individually. If the noise changes or goes away, it's probably the pulley you're addressing at the moment. This is an easy trick that may help!
