How to identify this squeak

[Thunderhead]

So every once in a while I hear some squeaking going on. Heard it and open the hood. So how should I isolate which pully is making the nose ? Spray some lube on one at a time ?

I'd Pull the belt off and try to wiggle the idler pullies. There are two of them, one just to the right of the alternator and one on the tensioner. When I did my water pump recently, both of mine were worn out...they are relatively cheap. Made the engine a LOT quieter.

Did you replace with OEM or a different brand?

Different Brand...Went to Autozone. I'll spring for OEM when necessary, but for a pulley, I don't see the need. They had decent, name brand bearings and that was good enough for me.
