The squeal when first started is most likely coming from the alternator belt. You need to have the tension of the belt checked to make sure it is properly adjusted. If you had a shop due it have , have them recheck it. Or stop by a local shop and they shouldnt charge you to check it. But its all in how you ask, if you go in and tell them your problem most likely they will try to get you for a fee to diagnose it.Just ask to have them check the belts and make sure there tight.If its ok, has anyone tried to fix your sqeul by spraying anything on it? if so your belt could be slipping from the lube they used. there is one more thing you can try, providing all the pullys/ tensioner pully if equiped are straight. If it is a serpantine belt(flat/multiple grooves) not A v-belt
when the engine is off,you take a tablespoon or so of corn starch, yes the stuff in the yellow box in the kitchen, and put it on the inside oif the belt. Its acts like a dry lube. I learned this trick at the GM dealership, from a factory bu;lliton. good luck

NOTE: Do not use any type of belt dressing or restorer on Poly-V Belts.
