Based on your description it sounds as though you are low on coolant. Have you noticed any coolant leaks on the ground under the vehicle? When the engine is cold checked the fluid level in the reservoir and the radiator. Do not attempt to remove any caps or pressurize systems when it is hot. Let me know if you find the coolant to be low and we can go from here.Skyvisions
