I know its been a long time sense posting. But it did turn out to be the water pump. I had a mechanic put in a new one. But now I have another problem. When I start the vehicle I can hear gurgling coming from the heater core in the dash. The heat still works, and its not leaking from the core. I think mechanic didn't bother to run the heat wile filling the coolent, and that maybe why. But the main thing is. The little hose that runs from the top of radiator to the reservoir tank leaks. Right where it connects to the radiator. And there doesn't seem to be any clamps at either end of the hose. Is there suppose to be?
