    Just take the radiator cap off and put the flushing "T" in a heater core hose. After flushing the cooling system until the water comes out clear then take the lower radiator hose off to drain the water.

    Buy full strength antifreeze. There will be around a half gallon of water in the motor which you can't get out. Pour 1/2 gallon of straight antifreeze into the radiator first. Then dilute the remaining antifreeze so it's a 50/50 mix and add it to the cooling system. Run the motor for 15 minutes to purge all the air from the cooling system and you'll end up with a -35 degree protection level.

    Do NOT do it.  Flush the coolant properly with the engine OFF.

    Bad idea. the engine will instantly overheat.

    That is a good way to damage the engine and NOT an effective way to flush the coolant.

      I will shut OFF as soon as all the fluid is drain, it will talk only 20 second to flush all, and engine need atleast 1 min to heat up.
