Default noisy belt

Anyone have any hints on quieting a noisy fan belt short of replacing it? It's on an 86 L98. Some have suggested spraying WD40 or rub soap on it.

is it cracking? Also, my belt used to make alot of noise because the compressor had went out and was locking up, it was on the verge of breaking the belt when i unplugged it.

Two things.

If the belt has 5 or 6 cracks per inch it definately needs to be replaced. When you do, clean, I mean really clean, the grooves in the pulleys. (all of them) it should run quiet then. Is there any vibration?

No, I don't notice any vibration, and the belt doesn't appear to have any cracks or deterioration.
