Re: coolant overflow

A couple of possibilities are the engine passages or water distribution tube is full of sediment and hindering circulation to point water is actually boiling in places & turning to steam pushing water out or the head gasket is blown and combustion gasses are doing the same. Since the water pours out when engine stopped, my guess would be the steam. A slim possibility might be the water pump or thermostat is shot and not circulating enough. Does there appear to be good flow in radiator when thermostat opens or engine warm but not to point of boiling?
