I checked the fluids and it did need power steering fluid. I added what it needed yesterday afternoon and the noise when turning the steering wheel is completely gone. However, the noise coming from the belt/water pump area is still there. I checked the pulleys and none of them seem to have any play, although I have not removed the belt yet. I also noticed a crack that runs along the edge of one pulley and took a picture of it. Do you think this will need replacing?
