2 - Lock them off in sequence with the rad first, then stat, then the rear one by the engine mount when water flows in a steady stream.
3 - Leave the header tank in and run the car, keeping the water in the header tank higher than the heater matrix level (about halfway up a 2l coke bottle with the bottom cut off).
4 - Run at fast idle, just under 2000 rpm and keep an eye on coolant in header tank. You will see air bubbling through and you need to keep topping it up.
Don't fill it too high because as the thermostat opens you will get a big rise in coolant level which will settle down again.
5 - Let the theromostat open and let the fan kick in then switch off and let the car cool fully, then remove header tank and top up if necessary.

mmm not quite.
1 - fill it from cold using a header tank, make sure the level of the header stays above the height of the engine.
Engine off and cold, it must be cold and the car must be nearly level or facing down hill.
2 - open the bleed on the radiator until there are no bubbles, then close it
3 - open the bleed on the thermostat housing until there are no bubbles, then close it
4 - open the bleed on the heater matrix hose until there are no bubbles, then close it.
5 - remove the header tank and fit the radiator cap. Any excess coolant will spill off and the level will correct itself (max is like half way down the coolant tank on the radiator and it's really hard to see)
