Try to get the expansion bottle higher than the bulk head when doing what munster suggests. Failing that (it didn't work for me) you can remove the hose off the return side of the control valve and with a totally full expansion bottle start the car. After a few seconds and with the engine still running you can put the hose back on and that should be it. Its pretty messy though and make sure you don't run out of fluid in the expansion tank as it can damage the water pump if it runs dry. Maybe have someone handy to turn the car off just in case you struggle to get the hose on in time. Whatever you do please dispose of your anti-freeze responsibly - cats (and other animals) love the taste of it and it can kill them.
