Do you have a coolant reservoir? What's the fluid level look like, engine hot? New radiator cap? If coolant gets too hot, it will pop the radiator cap and the overflow bottle, where applicable, will fill up or overflow. Some makes and models, I remove the thermostat, then hook everything back up. Then the flow through the radiator is instant. Some radiators, I can see or feel the coolant flow. Radiator is full? Remove the cap, watch the coolant, if it starts rising instantly and overflows, sounds like combustion gases getting into the coolant.
