Today i was gogin to open my grague and herd my engine chirping so i opend the hood and it sounded like it was comming from the alternator but it is a new alternator so i turned off my ac jsut to see if that was it but it was still there the noise went away allot tho but was still there. So i figured it might be the tensioner could that be a possibalty? how would i know if it was the tensioner my tension is perfectly. The other thing is last week i took my car and pressurewashed the engeing so im wondering if i cleaned away the greese on the pully. Any Ideas?

 

or maybe you got grease on the pulley or belt. wipe them all down with a clean rag, or use belt dressing on them to clean the belt

 

ok, not compltley sure what your trying to say. but i think you man a belt is squeling right? if this is the case, tighten your tensioner, shuld be one pully that will move to tighten or loosen your belt setup, having never done this before on a thirdgen i cannot tell you witch one it is, i know on my old jeep charokee it was the alternator ( i think) annyway, tightening that should fix you right up. hope this helps.

 

If you had your AC on and it was doing it bad, then you turn off the AC and it still does it some - I would say AC compressor. That's exactly what happened on my 1994 Grand Am. I hope I'm wrong for your sake.

 

Your tensioner is going bad. Belts will chirp and squeal if tension is not strong enough and belt will slip.

 

I went and stuck my ear down by the AC compressor when i herd the nose but it was more by my alternator and tensioner. It is a new belt on the car and the tension mark lines up perfectly. It just makes a chirping noise and it is drivng me nuts im almost 100 percent sure its comming from the tensioner.

 

take off the tensioner (easy) and then spray the inside of it with WD40 or something, let it sit and then put it back on.

If it stops squeeking, then you need a new tensioner (WD40 would only be a temporary fix)

if it still squeeks, then yout tensioner is probably fine.

 

glad to hear it wasnt the compressor. it's a pain in the ***.

 

Would moly lube or bearing greese work better then wd40???

 

Better than you rear...
take a LONG screwdriver, place the metal end tip on any part ya suspect, stick the handle, toward, your ear.
You'll hear exactly where the noise comes from that way.
The noise travels thru the screwdriver that way.
Going to be by my Van Nuys house alot as I'm refinishing the floor. Stop BY!
If ya see a car & dust escaping from windows, I'm there!

 

ok, time to find the noise... for real.

get a long solid rod, 18-24" and place one end to your ear, the other to various parts.

Trust me, you will find the noise quick. I thought I had a shot lifter, and turned out it was an injector.

You also do not have to have the "probe" diretly on the part, just really close IE (the tensioner)

 

Hopefully it's not the water pump... do you have an idler pulley instead of an AIR pump?

 

Its not the water pump the waterpump is like 2 months old. I do have a smog pump on the car. Im 100 percent sure its the tensioner pully just because i hear the noise from that area and when i turn the ac on it gets louder at the tensioner. How hard are they to replace i remeber hearing a long itme ago that the tensioner pullys go on our cars very often. I think i wil take it apart whne i get a chance and put some greese in it and see if that will help.

 

undo the serp belt. undo the 2? bolts. watch it fall off in your hands. put on new tensioner, put on serp belt.
total time, maybe 20 minutes, if you take a beer break in the middle.

 

any one know where i can get the gm part number for it or any site in general where i can get gm part numbers? The dealerships here wont give them out any more. I have no clue why.

 

i think my car is doing the same thing .. but the thing is it only does it while im driving and my car is at or about a steady 1250 rpm with steady throttle pressure... (as soon as i let off the gas or give it more it seems to go away...) usually around 30 mph in over drive... i cant firgure this out... can it be my transmission squeeling ... (*** i hope not) or can it also be a pulley or belt thats screwed up?

 

It was a combo of my lifters and 99% of the problem is my tensioner pully the bearings are 100 percent shot. 35.00 from gmpartsdirect.
