Good day, when driving the car on a speed like eighty to one hundred mph the overheating will start. The radiator normal short coolant with A/C or without A/C. I need help.

How does it overheat? Just hot on the gauge or does it actually start dumping coolant out? First thing I would do is check the radiator and AC cores for dirt/leaves and such that may be blocking airflow. Then have the system serviced. High speed heating is usually caused by a water pump not moving the coolant enough, either through blockage in the radiator or the pump itself is worn.

It overheated after driving it like thirty minutes. The head gasket has been change and the water pump and radiator is working well, but still yet the overheat is there. The radiator normally short water but when there is water inside everything working perfect. What can I do again?

Sounds like you have a leak someplace if you are losing coolant at all. Run a pressure test of the coolant system to see if it holds pressure.
