squeeling noise after water pump and belt replaced on 2007 Dodge Grand Caravan

just had the water pump and belt replaced in my 2007 grand caravan and now there is a squeel coming from the engine any ideas what it may be?

The serpentine belt may just need a tension adjustment. Take it back to the service faciltiy and have them re-check it. There may be other problems, but this will be the first thing to look at.
