So every time it rains and I start my car afterwards, there is a light squeal that seems to last for as long as it takes for my engine to warm up. Is this normal or a sign that I should go get my belts checked out. It's not too loud so it's not hard to deal with, but it does get on my nerves. I want to reiterate the fact that it only happens after it rains. It's a 04 coupe 6spd btw. Any input would be much appreciated. Thanks in advance.

Id get your belts checked.. Mine did that and after changing them it went away..

belt is probably stretched or worn that a lil moisture creates the squeal. It tightens up when heated up so the sound goes away. you'll likely get the squeal as the temperature drops as well.

either get a new belt or tighten it up and it should go away.

Which belt would it be?

go ahead and change both out since youre already in there. btw, buy oem belts. they are felt lined and quieter than aftermarket ones. about $30 for both but worth it.
