You mean squealing/screeching? Is it serpentine belt? They can look ok but still be worn out. The grooves wear too wide and bottom out and slip.

Try to isolate cause of noise with tube to ear ot auto stethoscope. Could still be a bearing like alternator or AC.

Alternator is ok took it to autozone. There is a recall on the Fuel Pressure Regulator could this be the problem. If not when they fix the recall I will have them check the serpentine belt.
