You did not say if you noticed any leaks or wet spots on the ground. There could be a couple problems. It could be a circulating problem where there is a circulation blockage. Air circulation going through the radiator is clogged causing it to overheat, A head gasket could be blown. Do a pressure check on the system. Most Automotive retailers have kits to borrow to do one. Or you can go to a garage and have one done. You did not say anything about any smoke coming from the exhaust. If there is white smoke could mean internal problems. When you say you added water was it just the overflow or the radiator and overflow?
