It's usual to trun heater controls to 'open' (i.e., hot) and pull the small 
hose off the bottom of the radiator.  It trickles at first, but as the air gets 
in it suddenly rushes from both ends at inconvenient moments.  It is indeed a 
trick of the true master to get it all into a single bucket without a sleeveful.

IMO - they're all much the same.
