Sounds good. You could even start the car and let the water pump circulate the old coolant out. Wait until it's running out clear and then drain some to make room for antifreeze.

a better way to do it is to remove the cap and loosen the drain plug, after that put your hose to the heater hose and let it run till its clear.

I like to remove the thermostat and replace the housing, remove the lower radiator hose, and then reverse flush from the top side back through the engine. After water runs clear, do the same with the heater core by removing both hoses from the engine and flushing it also. Then do the radiator to get any loose debris out of it. Watch the pressure, splitting seams in the radiator or heater core isn't any fun. Doing the three areas separately does a better job.
