I think you might find its the head gasket leaking allowing combustion gases to pressurise the cooling system. Sniff test of the coolant will tell you.

Defo head gasket. Straight forward enough (I changed one in a French hotel car park once) but not for the feint hearted.
You also need to find out what caused it to fail in the first place, which is usually compromised cooling, which could be a blocked rad, knackered water pump, leaking heater matrix.......
