If that'* as painful to listen to in person as it is in the video, I can see why that bugs you. Gads!

I just re-read the first post, and noticed that it'* an Autozone tensioner on there. I know you said that it spins freely, and that WD-40 didn't help, but my guess is that something is wrong with that tensioner. Maybe it just binds up a little under tension.

Only way I can think to test that theory would be to take the belt off and apply as much pressure as you can to the tensioner pulley as you turn it a bit, and see if you can get a chirp out of it.

Personally I can't see it being the belt or dirty pulleys, since it'* slipping at idle, with no excessive load or anything. Still, a cheap(ish) thing to try.

EDIT: Actually, if you were going to throw a belt at it, I'd go for a Gatorback like Bill suggested. If any belt will solve it, that'* the one.

Thanks for the suggestion, I did buy a Gatorbelt. But it turns out I need to go buy some tools to remove the bolt from the sleeve with.

I tried your suggestion with the tensioner, I applied as much pressure as I could with my hand and turned the pulley. It turned very smoothly with no sound.

I don't have any kind of jack to support the engine, but as long as I'm only removing just that lower part of the support bracket on the engine mount I shouldn't have to worry about it, right?

did you try hitting the belt with a quick shot of wd-40 while running?

A jack is helpful, but I've seen it done without. You should be fine.

You do have your trunk jack just in case you need to raise the engine slightly for re-aligning things for reassembly, right? That would be my only concern.

I think that'* a stud, too. Not a bolt. Just keep that in mind as you work.

Well, hundreds of dollars, around eight hours, and several thousand profanities later, it'* done. The belt change did it.

The sound of silence is...amazing.

Thanks so much for all your help guys. Even though the first two things I replaced didn't fix the noise, they definitely needed changing. The PS pump was definitely wobbly, and the alternator definitely squeaked when rotated. So nothing was wasted.

You know what really sucks about this experience though? While my poor car sat crippled, missing one wheel and having one corner in the air for a few days, an army of birds came and crapped all over it.





This car was like a mirror not two days ago. Oh well, better to have a dirty car than a broken one.

Thanks again for all your help, I guess it'* time to go drain the PS reservoir and flush it out a few times...get everything all assembled, clean myself up and enjoy a little test drive.

Glad it'* gone at last! I really didn't think it could be the belt. Shows what I know, eh?

Hopefully it stays fixed. Now, wash the car and/or get yourself a shotgun to deal with that issue in the future.
