Q: High pitch squealing while accelerating. New water and power steering pump

asked by on

When accelerating from a stop, car squeals very loud. Changed power steering pump and belt pulley, and water pump. Noise continues...does not make a sound while idling, but when it hits about 2000rpm the sound starts. Please help me!!

My car has 190000 miles.
My car has an automatic transmission.

Hi Brandon. Thanks for contacting us tonight. A squealing noise is typically caused by a loose belt - like a serpentine belt that drives the water pump on your Pontiac. It’s also possible that one of the pulley’s is causing this noise or even a wheel bearing. Regardless, this is something that should be inspected by a professional mechanic on-site to correctly determine the exact source and to recommend or complete the right repairs.
