How bleed air from water system on range rover 2003?

Top up with correct water anty-freze mix, take cap off expansion tank, turn on engine and allow to idle for 3 minuets or so, you can watch the bubbles coming up in the expansion tank. strongly massage the return pipe, big pipe on the top of the rad left side as you face it, coolant should shoot into the expansion tank as you do this. once it is cool check if you need to top up coolant mix and off you go.

ps do not take the cap of the expansion tank when the engine is hot.
