flushing cooling system

[GhettoPop]

whats the best way? open petcock, drain, adding water and flush, run engine till tstat opens, turn on heat, drain, repeat with water, then fill with antifreeze. i think this is what most people do. i realize this does not fully flush out the block.

i have heard of reverse flush, disconnect upper rad hose at tstat, take out tstat, insert garden house into empty tstat housing and let run for 15 min with the water exiting out of the disconnected upper rad hose, so it goes though the block and up then out of the radiator. is this the best way? is there a better why w/o having to remove the tstat? thanks.
