Not sure what belt. My dad tightened it so I don't know. All I know is he used a breaker bar to pull the alternator away from the block.




It usually only happens when your first crank it up and gun it and also when water gets on a pulley or on the belt.

 

... i have never seen nor heard of a pulley being so worn that the belt is not sitting in it right.


you guys do realize that a V belt isnt a V belt and that there are different series V belts and they vary in width right?

the belt should be flush or JUST slightly above the diameter of the pulley. if the belt is sitting down inside the pulley, its the wrong belt. length may be right but thats it.

 

good lord i never use a pry bar to tighten a belt

 

I do. Granted, I'm running two belts on my alternator/wp/crank.

 

I know about the different widths, but this was the one I had on the car since I bought it. Now it has 1 that is the same width but about 2 inches longer.

 

if that thing is not adjustable how else would you get it tight without a prybar? it's the easiest way. anything else is just hassle

 

My squeals now too (when revved quickly), but only because I've removed my power steering so I only have 1 V-belt for the alternator. It was fine before I removed my power steering so I think I just need to tighten the belt some more... I'll probably do that today.

and my dad has always used a broom stick to tighten the belts. He would pull the alternator or p/s pump tight and I'd tighten down the bolts

 

All three of you guys might try using a belt a mm or two wider....

A "V" beld should ONLY ride on its shoulders, not the inside radius.

Cheap and easy enough to give it a try...

Worked flawlessly on the truck I did this on..

It only had about 300,000 miles on it when the belts started slipping.

 

I just might do that, i'll maybe replace my belt with the one that drove my power steering, it looked to be in better shape. I'll also see if the belts fill the whole pulley or not...

 

I can see on my pulleys that the belt is not bottoming out because there is some brown surface rust/patina in the bottom groove but where the belt runs it is smooth.
