First of all I'd thank you all for always being so helpful.
Now tonight as i was trying to park my car, i was struggling with all this frozen snow so i got in a situation where i was completely stuck, and as i was hitting the gas i heard a noise cuming from under the hood.
It was one of the pulleys rubbing the engine mount pretty hard.
Any ideas what this could be? im thinking maybe a cracked motor mount? i need help on this one i couldn't take a better look at it since it is -16 outside and its gonna be around -40 to -50 tomorrow :(
TY

I'm going to guess that your power steering pump is howling. I can't imagine a way that you could have broken mounts so badly that pulleys could rub on the car and it would still be drivable?

My power steering pump was ROARING when I turned my car on today and I live in the same area. I thought I wasn't going to make it anywhere, but the noise went away after an hour of driving. Performance was not affected. I fear it's going to do the same thing tomorrow, so I just ordered a new one in case I need to change it out in the near future.

With the car running, have someone turn the wheel while you have a flashlight on that PS pulley, you will be able to determine if replacement is needed or not. Good luck.

It does only when the car starts but it goes away,
i can clearly hear and see the PS pulley rubbing the upper engine mount. i hope its just lose and not broken or any other mount

You can "hear" it but have you actually looked under the hood to see exactly what it is.

It was dark and cold last night but i got to see what was happening, but not sure yet whats causing it.
Like i said its my PS pulley rubbing the upper engine mount really bad.
I guess due to rough movement, i hope its just lose, im not sure where the the rest of the engine mounts are located

I doubt it's the engine mount. The top mounts don't really go bad, and there's no where for it to go. It's the rubber in the front/rear transmission mounts that usually goes bad.

If the PS pump pulley is rubbing on the engine mount, I'd be more inclined to say the pulley itself is bad. That happened to me this year. The stock pulley on older cars is plastic pressed onto a toothed metal hub. The plastic gets brittle from heat and age and cracks, and all the teeth strip out or it works it's way out off the hub.

Like this.

Went to the dealership and bought a new one, and it was a new design that was one piece, all metal. Much beefier.

Bahahaha!! Damn I forgot how low that pulley is on the car and how tight the 3400 is in the alero. I've got the 2.4. I also forgot that the 3400 pulley was plastic. I've had this happen on friends cars before too. That was a crap design! Good thing you can buy better replacements!

Be careful and don't drive it until you can fix it.

Is that pulley better than the one they have at autozone?

Well, I don't know what they have at AZ; the link I gave you is for the OEM pulley (made in Canada).

Who you talking to, him or me? Mine's been fixed for a long time. ;) That was from last spring. We don't know if his is the same problem or not yet. He still has to go check it out. That's just my guess is for the problem at this point. :)

Well I don't know what pulley they carry at autozone, but the one Matt posted is the same one I got from the dealership.

GM improved the design. It's not expensive either, so I'd go with the OEM one, unless they have the part in stock at autozone and you can look at it first. It should be similar in design though. I wouldn't get another plastic one. You'll need a power steering pulley removal/installer kit to replace it as well. They should be able to rent you one at the auto parts store.

Wish I'd known about the new PS pump pulley back when I did the 3500 swap.

I look at it today and the pulley looks a bit cracked so i gotta replace it anyways.
I never thought t he pulley would come out lose, and yes the pulley feels a bit lose too.

Last time my alternator bracket cracked by just turning a little fast out of a parking lot, i imagine if i do a burn out this thing would probably tear down in peices
