What if we open radiator hose and start the engine to completly flush coolant 1min?

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.Source(s): Mitsubishi Master Tech

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.
