Pulley Squeaking
on a side note, could i have fucked anything up on my undercarriage that i might not notice until later?
If you hit some water I'd let it dry before doing anything.
.
And your cut-out being unbolted doesn't matter, water can't go up into the engine via the exhaust as long as your engine is running, even if the cut-out is completely under water.
.
I've also never heard of a crank pulley being the squeaking culprit.
Squeaking is usually a misalignment of an accessory or one of the 4-5 pulleys in there being either misaligned or they have bad bearings. I think there's 3 fixed pulleys and than you have one tensioner pulley up top and one tensioner pulley for the A/C belt down below.
I think when the belt is spinning and its warm, then gets wet alot, it kind of gets grimey and nasty. Dirty water and rubber leaves grime behind and now its all over the whole pulley system. Like if you go out and wipe your finger across it, will it get all nasty black on your finger? A new dry belt won't do that at all, it'll be clean. Let it go for a few days and see if all the crap gets burned off/away.
Every time I clean my engine bay it squeaks for at least one day. It always goes away.
