If you are really desperate to flush the coolent system and you cannot access the lower bung. Then just disconnect the upper hose at the engine end and pour you demineralized water into the upper hose while the engine is running.

You might need a second helper. And puting the water into a bucket allows you to have a quicker supply of water into the hose while the engine is running.
