'04 radiator flush question

[bob'smerlot]

From what I can tell, removing the engine block drain plug might be a bear. Always one that believes in 'work smarter, not harder', plus I'm a little lazy, why not just leave the darn thing alone. Do the simple drain, add more d i water, circulate, repeat several times, measure the amount of water that drains, subtract against the original 10.5l capacity, & add concentrated amounts back in to get me to the desired 50-50. Only thing it cost me was several cheap gallons of distilled or DI water. Thoughts?

My suggestion...

Buy a Motive power bleeder with quick release fittings. You need one anyway to bleed brakes and the clutch (if you have one).

Motive has a neat little adapter that threads into to bleeder screw port used on most BMW cooling systems. You can pressurize the cooling system at 16 PSI or so, then power drain the system through the radiator.

And that will drain the block also?

Nope, not the same thing. You have a vacuum bleeder. The Motive is a pressure bleeder that pressurizes the master cylinder. You can use it dry to pressurize the cooling system with the motive fitting.
