4th Generation Squealing during acceleration

Im not sure where the sound is coming from... but whenever I accelerate or press on the gas, there is a squealing sound. The squealing sound subsides if I release the gas pedal, but continues when I push on it again.

Any thoughts as to where it came from?

maybe the serpentine belt? Does it squeal when you first start the car? Does it squeal when you rev the engine in neutral?

What acessories, if any, are you running when the squealing is present? Does it squeal if you accelerate hard in reverse?

It does not squeal when I start the car, nor rev engine in neutral. I have not tried accelerating hard in reverse, but no accessories.

...no serpentine belt on these vehicles.
There is a timing belt .... has it been replaced within 60k miles?
There are two accessory belts .... power steering and alternator. Have they ever been replaced?
What is the maintenance history of your vehicle? What is your vehicle?

Just a wild guess .... but there is a timing belt idler pulley, within the timing cover /belt assembly that has sealed bearings, which can wear out after high mileage.
Maybe try to listen with a stethescope or other sound device and locate the area of the noise as you rev the engine ... in park.

My friend had a similar problem on his 240sx. He said something about coolant leaking on the belt..?

I am having a problem similar to this one. But it only happens very rarely, like once every 5 trips as a rough estimate. It only does it when I accelerate, but after I let off the gas and push down again it stops and never returns (until next time...).

i had the same problem, its definately the belt that runs the alternator (brain fart cant think of its name). it happened to me like 6 months ago. i tightened the belt and it kind of fixed it so i just replaced it and made sure it was tight. havent had a problem since. the old belt wasnt that old so my guess is that it just randomly got a cut or something in it somewhere lol

If it doesn't make noise in P/N, then it may be transmission related.

One of the things to check is ATF level and condition to see if it's low.

I would suggest checking for any leaks with a flash light and a piece of card board under car over night (if possible). belts love to squeal when wet...

JohnGD makes a good point about checking fluid in transmission. make it hot by driving lcoally for let's say 30 mins locally (since cold start in now cold weather) then on running car check fluid level (you may need to go through all gears on selector back and forth to make it accurate reading).

note the color (should be clear red/pink) and ... smell it also. if it stinks badly, prepare for a flush... soon.

Is there smoke rolling off the front tires when you hear the squeal ? If so it's your tires spinning making the squeal.

Solution: Stop hitting the NOX button or remove the super charger.
