I think you guys are right. The pulley that makes the noise is the one that doesn't drive anything. On my car it's between the alternator and the PS pump. It is held in place by one nut in the center, but it is pain to get to. Is that the idler pulley?
Now semeone please tell me how exactly did the belt dressing messd it up since its bearings are sealed and it couldn't get to it? Also, why is it that every time I spray little wd-40 like lube on it the chatter stops till the next morning I first start the car?

At work in ye olden times we investigated a variety of elastomer treatments and potential cleaners, including 'belt dressing'. The stuff just swelled the material, which made it worse once the swelling went down. I'd replace the belts and anything else that it came in contact with, especially radiator hoses.

all I can say there was and still is no problem/damage with crc dressing on my BMW (stated above). This stuff is clear, very thin and slightly sticky. The can states it was for V or serpentine belts. It worked when I sprayed it on the PS pully/belt area. However, I do not think it lasts but a few weeks.

However, M50 and most newer BMW engines use plastic idler or tensioner pullies made with sealed bearings. These are wear items and need to be replaced periodically

I know I am going to catch some flak for this but this is my experience with my 2000 Jimmy 4.3. I treid EVERYTHING to get rid a a belt squeal. New idler pulley new tensioner new gates serpentine belt cleaned the #%^#$ out of all the pullies with water+degreaser (simple green). Everytime the new belt started sqealing after 2 weeks. Tried new belt again (warranty) same thing. I finally asked a guy that works at a shop what do you do when someone complains about a sqeeky belt and he told me "dielectric grease" yes the stuff you put on your spark plug boots. He said "put about a 1 inch blob on the front and backside of the belt and it'll go away" I thought no way this is going to work but I was so tired of hearing the squealing I didn't care and tried it. That was 4 months ago I haven't heard the squeal since.

Take it for what its worth, it worked for me.

That dab of silicone based grease did the trick?
I will probably try this in the future!

Yup, put a blob on the front and back of the belt fired it up, the blob disappeared without mess and have been squeak free ever since then. Also have a backup pulley and tensioner in case the new ones fail .

The dielectric grease was in a red and white can sold at pep boys had the long tip on it to go into your spark plug wire boots I think CRC made it if your wondering which kind I used.

Thanks for the tip Iceberg! I have had to replace the belt on my 2002 Silvo 4.3 every 30K miles due to squealing. Last time I put on a "gatorback" and I am hoping it lasts longer, but if not I will try dielectric grease. RW

Bump:

I've had a power steering belt squeal ever since I put new Gates belts on my Corolla a few weeks ago. It'll start to squeal when cold as soon as I start turning the steering wheel. I can fix it by cranking the belt on as tight as I can get it, but I'm not going to do that for long as it'll burn out the bearings in the pump.

Lo and behold I found this thread and researched the di-electric grease trick. From what I've uncovered, it works so well that car manufacturers have even used it for TSBs for squeaky belt issues!

So I gave it a try and it works! At least this afternoon. LOL

People say it works better then belt dressing and it's almost a permanent cure.

OK, well, the grease trick worked for about 10 minutes.

I've determined my steering rack is binding up and putting too much strain on the pump, or the pump itself is on the way out. This only happens when the vehicle is not moving and you try and turn the wheel.

I had a severe curb hit a few years back and I think that damaged the rack.

I put in some Lubegard power steering additive and am just going to live with it until it totally fails I guess. It's fine while I'm moving, and there isn't any tightness in the steering.

I gave this deal one more shot by cleaning the heck out of all the pulleys with brake cleaner and I bought a set of those new Dayco W-ribbed belts that are supposed to solve problems with old worn out belt drive systems.

http://www.daycow.com/

They've stopped the squealing cold! BUT, the edges of the alternator belt are already frayed with just 10 minutes of operation.

I'll be keeping a close eye on that. They look very beefy and of good quality and after an initial run in, have stretched 1/4 what the Gates belts did. I don't know if Gates quality has dropped or what, but my car did not like them at all. They're made in Mexico as well; the Daycos are Made in the USA.

http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1636170#Post1636170

That was my initial belt problem post.

I've NEVER had issues with belts until this new set.

I was always a Gates Belts user. AAP cut me a deal on Dayco belts recently for my Aerostar and I was very pleased with them.

I have excellent results with any type of belt dressing.

For 2 minutes or so. After that, it is usually worse.

First, check your alignment of the pulleys. Common sense shimming with washers or whatever can often fix this.
