I was driving for a while today, then suddenly at a stoplight I started to hear these squealing noises coming from the right side of the car, originating from the engine bay. The noise occurs whenever I stop at stoplights and occasionally at low speeds (I guess it’s the vibration). Then when the car is in park, no squealing was present.

I am guessing that the noises are coming from a belt, but as to which one it is, I don’t know. Could it be the TB??

Please Help!

Thanks

The timing belt would not be the problem. One of the drive belts or a bearing or the timing belt tensioner.
Usually, the problem is a loose drive belt.

Exactly, Peter.
Question to 'Gride_Cruiser': That noise is being increased during accelerating? Yes? -Mike

To isolate it. Do these things one at a time.
When it is sqealing-
1.Turn on or off the a/c(creates a load on the a/c belt). Does the sound change?
2.Turn on the headlights(creates a load on the alternator belt). Does the sound change?
3.Rotate the steering wheel left and right(creates a load on the power steering belt). Does the sound change?
This should isolate which belt or component is sqealing.

Hey, I know you do that to keep your car running at tip top shape, but that's not for me! lol

On a serious note,

I took the car out for a 15+ drive today, and no squealing was heard from inside, "rather" there was a mechanical/static sound coming from the center console, the A/C area, but that subsided after 3 minutes of driving (maybe I've never noticed it before I got paranoid).

After driving I left the engine running for a bit, popped the hood, I could still hear some sort of squealing but very minimal (EDIT: this is from outside not inside). I did all the tests suggested, I am not quite sure but the squealing may have been a little louder when I turned on the A/C and headlight?

EDIT: After a bit more driving, I followed the same procedure described, and could tell no difference whether the squealing was louder under different conditions... I toggled the belts as well, they seem to be fairly tight...

Thanks

As the car heats up, the metal parts attached to it also heat up, including the pulleys. They expand when hot, and the belts don't slip as much, cause they are now tighter due to the bigger pulleys.

If it is a loose belt, it will make the most noise when the engine is stone cold, and yo blip the gas to rev the engine.

But there wasn't much change in the level of squealing from cold engine to hot, wats "blip the gas to rev the engine?"

Thanks

Just don't hit any of the coil packs when you do that. :giggle:
:eek2: .... lol... ouch, soprano scream.. they should have about 10-15mm total flex at the longest stretch of belt, anymore and theyll need tightening

When you say the right side of the car, is this when sitting in it or looking at the front? And you also say that its at low speeds when the noise occurs, correct? The only pulley on the passenger side (right side when sitting in the car) would be the power steering pump, this is also the only one that experiences a change in load with speed. What I'm saying is that when the car is at a higher speed the A/C or alternator belts (and pulleys) don't have a higher force to transfer, but the PS pump would b/c of the speed sensitive steering system, more pressure (power assist) at low speeds, less at higher speeds. It sounds to me like something with the P/S pump, and there is no tensioner. But I havent heard of a P/S pump bearing going out before. Make sure your P/S fluid is at the correct level also.
