OVERHEATING - blowing out coolant

Bru. Thanks for the reply. Coolant is being blown out into the overflow, and then completely out of the overflow tank WHILE BEING DRIVEN.

Everything had been changed on the car. Thermostat. Fuel injectors, Radiator cap. Radiator, Fan Clutch. Water pump. You name it.

Originally had an oil leak from valve seals. Had that work done and when car was given back to me, I overheated and blew the HG on the first day. They replaced he HG, and it overheated again !! So they said instead of doing this again, to replaced the engine. Had the engine replaced, and then overheated the very next day. Replaced EVERYTHING as stated above. When nothing helped, I realized the car only overheated when it lost 50+ ounces of coolant, and could no longer cool the engine. The coolant loss is due to it being blown out of the overflow tank.

I now suspect the HG again, but it passes the Hydrocarbon tests, usually indicating an intact HG.
