Easyest way take off 1 of the heater hoses losen the clamp on the bottom radiator hose open heater tap take nozzle off hose push hose into heater hose and turn hose on to low medium pressure when the water starts to over flow out the top of radiator drop bottom hose drain push bottom hose back on then repeat. Do this until you have clean water coming out. That way you have flushed complete system. Then refit bottom hose tighten the clamp, same with heater hose.Put about 5 litres of water in the radiator then add required coolant then top up with water. Leave cap off start vehicle let warm up when top and bottom hoses have warmed up (providing your running a thermostat) wait for the air to escape out of the system when starting to really over flow then put on cap turn off. Dont forget to clean out over flow as well. Not a good idea to mix coolants.When cooled down recheck the over flow bottle as it will draw certain amount back into radiator.Save you trying to take out drain plug whuch still doesn't drain system properly anyway plus you can bet your life on it , it will be a allen key type head and you will probably not have that size plus some locktite when you put it back in so that it doesn't vibrate loose. Hope this helps you, and believe me toyota and probably most mechanics will not take out that drain plug and why try and remove something that has probably never been taken out in it's life. Regards Steve M PS Please dont be looking over the rdiator while waiting for air to come out incase it belches over your face. Not a happy outcome
