Answers :

I bought my '99 grand am used and 3 weeks later had a 'chirping' noise coming from the engine. The main belt was wet from coolant, ergo coolant was leaking. Found out it was the head gasket which was $1600 (canadian) to fix, but was covered by my warranty. Perhaps this helps?
Certain brands (cheapo) of serpentine belt will do this. It is because the new belt is thinner than the old belt. This causes reduced spring tension by the belt tensioning device. Other possible problems are a bad belt tensioner, driving through deep water and getting the belt wet while driving or a defective crankshaft harmonic balancer assembly.
I HATE Dayco brand belts, because they do this a lot. I would have the shop inspect the parts mentioned above. If they are OK, tell them you want a new belt (for free).
