What could cause a squealing noise when the engine is cold?

Answer

I suspect you have some loose or worn belts. Check the wear and tension, adjust and/or replace them. Probably the power steering belt. Good Luck Hope This Helps. John In Montana

Answer

most likely that first answer is correct. In the morning, your alternator needs more energy to charge the battery up from sitting over night. So it takes more power to turn the alternator, putting more stress on the belt, causing a loose or worn one to squeal until the battery is near or at full charge. just try getting the drive belts tightened, if that doesnt work, get new ones on.
