My 98 Grand Caravan with 114k miles squealed whenever I turned the A\C on. The noise stopped but the belt was gone so I replaced it, no noise but the next day it started again now that belt has burned off. I looked at the compressor while it squealed and noticed that it stops spinning for a second then starts again. Any advice will be greatly aprreciated.

If it is the 3.0, the belt needs to be tight. I've seen a bunch with belts that felt tight but just were not tight enough.

use a best available quality new belt, and yes, it has to be adjusted, DAMN tight!

Word to the wise:
Dont turn your A/C on under acceleration. let off the gas and then hit the button, or turn the defroster on.
It'll stop that cat-dying sound!

Thanks guys I appreciate it. It's a 15mm on the side & a 13mm on top correct & do you recomend power tools. :p

just wrenches will do the trick, you don't need power tools.
You may need a pipe or extension bar to hold the tensioner out.
