replace the radiator cap. if it doesn't hold pressure it will make the car overheat

Stephen Lee is right, radiator cap.
Or the radiator could be cracked in the plastic, mine had a very small crack in it that made it lose enough pressure to boil, but was very hard to see. -------------------- 1999 Celica GT

even if the HG is new, did you have the cylinder head checked for leaks and cracks?
