Belt Squeak or?
 

My car has been squeaking every cold start ( would remain longer if AC was on ) and would go away if I sprayed water on the belt. I decided to replace the belts even though there fairly new. My car now stops squeaking super loud like it used to, but has the smallest tiny squeak that goes away instantly. Is there any solution? I'm hoping it won't get worse. Thanks!

You need to check the tension on the belts. They are probably a little too loose but if they're too tight they'll squeak as well.

2nd the checking of belt tension. Every time I installed new belts, I'd have to go back and retighten after they stretch.

Usually when they squeak a little, I just go a tad tighter.

But in the FSM, there is a tension spec.
