It shouldn't make the noise. Is the belt, tensionier. All in good condition? Also, if they can't fix it, I would contact GM and explaine what is going on and demand your money back if they can't fix it. I'm sure the car went a lot of miles before this became a problem. As far as replacing the pump, there really isn't too much they could do to cause the issue. It is nothing more than a bolt on part.
