After 10 min driving starts squealing noise. Have changed alternator belt from narrow to wider one and changed air conditioner belt. Still squeals. Had alternator checked and it is good. Have tightened belts and have loosened belts and have put soap on belts. Nothing helps. NEED HELP!!!!

Check the crank pulley. If it has a harmonic balancer to it, it could be the one causing the problem.
