Saw this on another forum not sure if it helps.

"Hello, I found out the true problem why my belt was squealing, my radiator fluid resvior was leaking right on the belt. As soon as i got a new resvior and changed the belt again, no more squeal so check to see if your resvior is leaking. my mechanic checked my pulleys and belt tensiors, plus he even checked the timing belt tensiors too. So if your radiator fluid is constantly low and you have to refill it every once and a while. It may be leaking, my leake was a very slow leak and it leaked directly on to the belt.
