Thanks for all the replies.
I should have mentioned the procedure for my other car:
a) After draining from the bottom radiator hose, open the bleeder screw near the thermostat on the side of the engine.
b) Slowly fill the coolant reservior until bubble free coolant come out of the bleeder hole. This can take some time so be patient. Shut the bleeder screw.
c) Start the engine and idle at 1500rpm whilst topping up the system. Continue until the cooling fan cuts in.
Do you know if there is bleeder valve on the ML?
