Flushing an coolant system....
Whats the best wat to flush out a cooling system on a car?
Before I would just disconnect the bottom hose to the rad and let it all drain out, fill up with water, drain again untill the water was clear then re-fill.
Anyone else do it a different way? Or is there a "proper" way of doing it?

Well flushed the system out now, and glad I did too... I'm sure the water isn't supposed to be rust coloured
FFS I hope the guy that owned it before haddent dont that for the last two years 
Drained the lot, and put in 2l of anti freeze and 2l of water, that should do it nicely.
