The day I got my 94' I pulled up to a car show and everything was cool except for the minor squeak. An older gentleman came up to me and told me about the baby powder fix and I kinda laughed at first. When I left, the belt squeak got a little louder. So when I got home I puffed on some baby powder and by golly, that crap worked! Of course the squeak came back a few miles down the road. Me and my friend kept messing with it and we finally resorted to WD-40. Baby powder and WD-40 worked about the same, except the bably powder was a little easier to clean up. I messed with that for about a week, squirting oil on the pulleys and the belt, etc....
I inspected the original belt and it looked/felt somewhat ok.... Nonetheless, I went to Auto Zone and got a new belt and then I could see the difference. I also noticed some dryness and tiny cracks in the squeaky belt, since I could compare the two side by side. Belt never squeaked again after the new belt!
