No - you keep flushing it with clean water - that's the dilution process
I was talking about. You can even fill it with distilled water and
start the engine and let it go thru a complete warm up/cool down cycle,
then drain it again before refilling. It won't take any more time than
figuring out how to access and remove the block plugs in most vehicles -
and without the potential for something breaking to gain access to the
plug.

FWIW, whenever I *do* get the block plugs out of my engines, I always
replace them with brass radiator drain petcocks available at any auto
parts store (same size and pitch thread as the block plug)...
That's because it's all standard tapered pipe thread!!

Ahh! You win. I started to say that, but I didn't because I
couldn't spare the time to check and make sure I wasn't confusing NPT
and NPTF (dryseal).
