Cooling System Flush How?

[calais_304]

hi all,

very silly i know but how do you perform a cooling system flush?
The fluid in the raditor at the moment is a very pooey rusty brown colour and was told by the mechanic it has to be done and done soon, also a mate told me it's just a matter of undoing the bottom hose on the raditor and letting the hose go wild..but i don't trust that idea and thought i'd rather ask the experts.

so how is it done?

once flushed how much water/coolent do you need to put in? ie 50/50, 40/60..and how many L's?

what are some things to remember?

cheers all
