my belt squeals
I purchased a belt for my 7 and after a couple weeks it started squealing.
Its the alt, water pump and main pulley belt.
I tightened the belt and it is now maxed out on the alt, and now constantly squeals.
A friend told me to buy the solid belt for it, I have the one that is ribbed.
Ive heard of the yoohoo belt or something in those lines, what do you guys recommend I get.
I dont want to buy belt dressing thats not the proper fix

Well, here's the fix - and it requires removing the belt and reinstalling but will work. Get some 100grit sandpaper and with the belt loose in one hand, and the sandpaper curled in the other, run the belt through the sandpaper as your hand applies pressure. What you want is to scrub up the running surfaces of the belt so they'll get a better bite on the pulleys.
Now, on the pulleys take the sandpaper and lightly run it up and down vertically on the pulley surfaces - you don't want to sand around the pulley radially - you want to create minute scratches AGAINST the direction of the pulley to give it more traction.
You probably have some oil or grease on the pulley which will need to be cleaned off thoroughly and also check the belt to be sure it hasn't absorbed any of the grease or oil. Reinstall and you should be good. The tension on the belts isn't needed to be so tight as running them too tight will result in uneven bearing loads on the waterpump pulley and will cause pump bearing failure. Good luck,

This belt is shot, it is stretched to the max and you can see slack in it as it is moving.
I think I need a new belt

What belts are you guys using?
I dont want to swap it out again for the same belt, to have it wear out on me in a few months and buy another one.
I would like a good quality belt.

Never thought about that, I do not have an air pump installed.
But when I purchased the belt it said for alt, waterpump and main pulley only

Back when my car still had a clutch fan, it usually ate two of those dayco's every summer.
Of course I was running stock plugs and a very lean cruising carb set up. Usually led to a buildup of high heat in low speed conditions and the fan clutch would come on too much because of it.
Mine still squealed even with dual sheave pulleys and matched belts :P. But only when the engine was spinning up very fast with the fan still on.

Maybe you have an issue with pulley alignment?

It was more an experiment on my part than anything else. Eat belts and fan clutches it did though...

It helps a little, but before doing that just try a new pair of matched belts and a dual sheave.
The E-fan thing can be costly and even damage the engine if care isnt taken setting it all up.

There are a couple out there there are stock diameter. There's a steel one that's pretty cheap. There's also ones from other cars that fit. Sorry I can't provide links for you.
Currently I'm running the single pulley and gutted air pump, I don't like the amount of tension needed to keep the dual pulley/clutch fan setup from squealing. I had an e-fan setup and dual pulley and liked it but removed it as I was going to sell my car at one time.
