they didnt loosen a pulley or something by mistake? Hmm after the belts were done.., well you should have done it yourself
i was going to but i didnt have time, i had school finals and packing at the same time to move, trust me, if i have to ever do em again, im doing them myself...
do the soap trick. that will tell you if it's the belt or the pulley. if the noise stays, it's obviously a bad or loose pulley.
then you buy a stethoscope with a rod on it and place it near each pulley while running (BE CAREFUL, DON'T LOSE A GOD DAMNED FINGER). You will know which pulley it is, because as soon as you get the scope on it, the noise will be horrifyingly loud.
