Dont try to flush the radiator... when you drain it and try to flush it, what you will be doing is breaking up all the old gunk in the radiator, by breaking it up, you will have no clue if its completely clean or not, so if the gunk is still floating around, it could go threw the engine and clog up the engine, making it over heat and really mess things up... now if you want to just change the coolant, the drain plugs are on the botton corners of the radiator, theres 1 or 2 drain plugs... i forgot how many, but it would be alot safer to change coolant, then to try to flush the radiator.

At the bottom of the radiator there is a valve turn the valve and watch it go. If you wanna backflush the whole cooling system(good idea) remove the lower radiator hose and your block drain (lowest part of the block usually) and put a water hose into the lower rad hose and flush out all the crap
