440 cooling fault.

I would not say common place but it does happen, remove the upper heater hose from the front of the motor, fill the rad with the heater hose held up high, when water starts to flow from the hose fitting on the motor, stick your thumb over it and fill the pipe to the top, then quicly stick the pipe back on the motor, that usually works !
You MUST run the engine with a thermostat otherwise the water flows through the heads to fast and you get localised hot spots, you can run with the spring cut out of the 'stat so it is always open but it needs the flow restriction.
Is it actually boiling? as in can you feel the pipes 'bubbling' ? or is it pressurising but not getting hot?
Is the rad hot at the top and bottom?
Are the heater pipes both hot?
Is it losing water?
