I could hardly steer the car and it made all kinds of serious sounds so I replaced the power steering pump with a reman unit from my local auto parts store(not a national chain like AutoZone or Pep Boys). Now when I start up there is a very loud squeal that lasts anywhere from 30 seconds to two or three minutes. I have been squirting belt dressing on it, and it seems to have gotten somewhat less, but still persists. Is the pump bad, or do I have the belt too loose or too tight? HELP!!!!
