This pulley needs to be replaced. I isolated it after noticing a whining noise under the hood.

I've had an idler pulley make a similar noise in the past due to worn out bearings, which I replaced and fixed the problem. I think that's what's going on with this other one.

It's the one I highlighted in yellow.

thanks

 

Looks like just an idler pulley. I would imagine they are all the same.

 

I know it has the ribs on the wheel surface for the belt.

 

Yes, sorry. I forgot there are the 2 kinds of idler's....non ribbed, and ribbed for her pleasure...

 

Yes, this pulley is ribbed. Would that be a 90mm ? Just need to know so I can order the right replacement. Thanks.

 

To tighten the idler on an 07 v6 u jst losten it turn it a lil an tighten the bolt back right? Same as any older car or is ther sumthn i shud kno bout these newer modles?

 

Looks like it is the only one with ribs, not sure on the size but whoever you order it from should know that info.

 

Ordered a replacement. Thanks.
