Strange squeling; need help asap plz

Post by kinkyllama »

Gotta leave for work in an hour so hopfully its a quick fix. Very high pitch squeling sound is coming from what appears to be the TB. Not sure, but I really doubt its the timing or acc. belt. Its so loud that its louder than my exhaust, which if you heard that would tell you alot. It seams to go away almost completly when I'm in gear with the gas on and gets louder the more at idle it is. Also its seam to like to idle higher and doesnt wanna drop the revs quick at all.

Its so loud and everything I'm kinda afraid to do the "wiggle test" as I haven't an idea of what it is.

Any ideas?

squealing sound

Post by john_trickle »

My first guess is the neighbor's cat trying to get out from underneath the hood. However, if you see no hair then its something else,If you did not get the noise fixed yet, you might want to check on the pulleys where the drive belt is installed and/or the water pump. Pulleys make a high pitch noise when they are worn out either when you first start the engine or during acceleration. Water pump also makes the same noise. Check the little hole above or under the pump, if there is a sign of water/coolant coming out of the hole, your water pump needs a replacement. I hope this can help you
could also be worth considering your "clutch, thrust bearing,Or could be bearings wearing out in alternator, a/d compressor let me know how you get on.

Its the opposite...the noise happens when the engine is idling...the more gas I give it when its in gear (gotta check if I givce it gas out of gear if it has the same affect) the less noise it makes.

What hole is this? and where exactly is the waterpump? I know the general area but not specificly.

I'll take a look at everything tonight or in the morning.

The car had been running for about 2hours...half with a/c half without. When the problem started happening however the a/c had been off for at least 20mins. Also this is the first time my a/c has been used since around summer time. I also had my alternator tested a few months ago and it was perfect but I dunno if that'd reflect any problems coming down with the bearings.

Thanks!,

Found it!

It was a vacuum leak...doesnt sound like suction AT ALL though. It was one of the things on the TB where I took a tube off for either the coolant bypass or for the oil catch can.

Thanks guys for all your help!
