1994 grand am high pitched metalic sound coming from near pulleys

I have a 1994 grand am, 6 cylinder. It is making a high pitched metalic sound from around the pulleys or belt. Any ideas what it might be?

    The A/C hadn't worked for 4 years. I just got it checked and it would cost more to fix than the car is worth. But, if it is the A/C pulley (which I suspect because the tensioner was replaced a year or so ago) and I don't care if the A/C works, do I still need to replace the clutch so everything else with the belt works?

There are 2 pulleys that would make that sound. First would be the tensioning pulley, if the bearing is going out. Second would be you A/C clutch pulley, if it is going out. Look close at each, if one or the other is going out. You will see little metal filings below them.

This could be anything from the pump in the transmission to the alternator bearings/bushings to the power steering pump. Could be an idler pulley bearing, but I doubt it.
Hint: If the noise is very high-pitched, check the alternator. If it is a lower, medium-high-pitch sound that changes some when you turn the wheels, check the power steering pump. If it is almost like a moan or a "Whooo" sound, that's the transmission pump.

High pitch whining sound from engine


Check the power steering fluid if its low it could cause this. Also could be alternator, water pump, ac compressor, or idler pulley. My bet would be on the idler pulley, its the one that keeps the belt tension constant. Remove the belt and check this pulley for slack also spin it by hand.
Good luck, dont forget to rate.

There is a squeal sound (high pitch) coming out of


The seal on the AC compressor has probably failed and allowed all the refrigerant and lubricant to be lost. This allows the bearing to run dry and now it is failing and making noise.

1. You could have the AC repaired, the compressor repaired or replaced and the system refilled.

2. You could have a mechanic disconnect the system and possibly remove the compressor (only if this model does not use a belt that relies on the compressor being in place).

3. It is probably way too late to try to refill the AC system with R134a refrigerant as it would just run out past the failed seals.

If anyone has an AC unit that just recently stopped making cold air they should attempt to recharge the unit (if it uses R134a - check your manual or underhood stickers). I just did and saved my compressor and AC unit from further damage.

High pitch whistling noise in engine compartment of 2005 envoy


There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.
