howling noice -help.

Can anyone help me with a howling noise from the passenger side of the engine. Mechanic has replaced belt, tension pulley and waterpump. It only howls between 1,600 and 1,800 RPM while driving or in park. Suspect either power steering unit or alternator. Please help. Thanks

i get the same - i read a post about it being the alternator -- after installing new the noise was gone

Any evidence that this is a problem 2nd Gens. have?
