Car has a sqealing noise when its running while sitting still and warming up and even after warmed up and during driving and seems to get worse with turning steering wheel. Just got a new alternator and battery and this squealing has been ongoing for over a year. How can I find out what it is? Could it be a belt or power steering pump or what? I am a female widowed and just want to see what it is to stop the noise.

Belt and tensioner should be replaced at 60K recommended. It may be the belt.
