If its overheated it could of blown the head gasket. or warped the head. take the plugs out and see if it looks like its been steam cleaned in one or more of the cylinders.

feel of the top hose, if it's soft when the car is running and at operating temperature then it's probably air in the system, not allowing the pump to pick up the antifreeze. To get the air out let the car cool completely (like overnight) then fill the reservoir, leave the cap off and run the car until it comes up to normal operating temp. (watch to see you keep enough antifreeze so the tank doesn't go empty.
My 97 Aurora did the same thing and this fixed it.

Head gasket. The reason for the cold then hot readings is the cooling system is getting gas bound by exhaust gases. A simple intake leak would just make you loose fluid, but wouldn't cause the other symptoms until the coolant was very low. Which leads me to, is the coolant full? The head gasket most of the time will not leak coolant into the oil, but instead coolant will go into the combustion chamber, and exhaust gasses will go into the coolant. You don't see any white smoke until the leak gets extreme. Then shortly after that the engine hydro locks from too much coolant in the combustion chamber. There is a tester that will test your coolant for CO gas. That is the proof of a head gasket leak.
