Belt Noise?

Grrr I'm getting irritated with all these damn sounds my car makes. I pull into my driveway just now and before I turn off my car I hear a horrible squeaking noise. It's coming from my engine bay, sounds like the belt. The belt is only a couple months old so I don't think it's bad or anything. It has been storming bad off and on the past couple days, do you think maybe it just got wet or something?

I don't know how much this will help but I had the same problem a few weeks ago with my car after a heavy rain and driving through some water. I traced the noise down to the big pulley on the driver side up top( can't recall the exact name at this time). Anyway where the pulley rotates I sprayed it down with some liquid silicon now I had to do it a couple of times( and used half the can also) but after 2-3 days the noise did stop. Sorry that I can't give you a sure fire solution but it did work and the silicon is only a couple of dollars and can be found at any Lowes, Home Depot, or auto parts store. Hope this helps.

well if you were running the defogger or AC it could just have been the AC belt slipping. Most people forget to change the AC belt when they change the main belt.

Today I sprayed WD40 on my serpentine belt before going back to work for lunch and it made the noise go away. Well when I left work just now, when I fired her up, the noise was 5 times as loud as it ever has been, sounded horrible! I got out and sprayed WD40 on that top big pulley only which I believe is the idler pulley, correct me if I'm wrong, and the sound instantly went away. If it's only the idler pulley can I just replace that? It appears that would only cost like $10-$20 from what I'm finding on Google and Autozone.com.

Please advise.

Isn't there a bulletin regarding this problem? I could have sworn there was, but I did a search and couldn't find anything.

What's odd is ever since that one episode last Friday with the very loud squeaking when I sprayed WD40 on the back of the idler pulley, it's been completely silent now, no more squeaking at all. Watch, now that I've said that, tomorrow it will go back to squeaking.
