I have this high pitched squeal comming from the front of my engine. It's definately belt/accessorie related but I can't quite put my finger on where exactly it is comming from. It does get louder as the engine revs as well.

This only happened right after I got stuck driving in some serious rain, and when I say serious, I mean probably 4-6 inches of rushing water (flash flood).

It was brought up that it could be the tensioner, and maybe it got wet and ruined/flushed out the grease inside of it.

Any thoughts?

 

probably the tensioner, spray a little wd-40 on it see if that stops the squeak, if it does you have your answer, if not...
it is almost definitely a pulley and is usually the tensioner.

 

ac tensioner or the main tensioner to the left of the throttle body? or both?

 

usually the main tensioner

 

If it only happened once when all the belts and pulleys were wet then went away don't worry about it.
If it's still dong it then pull the belt off and rotate each item by hand. You'll feel which one is bad. It will wobble, squeak, or feel rough.

 

its still doing it. I guess I'll pull off the belt this weekend.
What size ratchet do you need to rotate the tensioner to get the belt off.

 

sprayed it with wd40 with no change whatsoever. Any ideas before I go insane

 

Did you spray some on the A/C tensioner too? Mine was doing almost the same as you described and it turned out that was the problem. Good luck!

 

i just went back out and sprayed the AC tensioner with no effect whatsoever. It's definately comming from the belt, a pulley/tensioner, or something the belt is spinning (ac, alternator, wp, something)

I guess sat morning I'll pull the belt and spin them by hand, see if anything is noisy and replace the belt just for the hell of it. It looks plenty good, and my car only has 25k on it, so its not that old.
