LightMan,

I do things as completely as possible. Using the block drain is a false sense of "doing it completely as possible IF possible". Using a garden hose to flush out the heater core, radiator, and other parts is doing it as completely as possible. That's what I did when I replaced the radiator & t-stat on my Dodge Cummins.

The way things have been going for the past year with my car, I've been draining the radiator every few months & have concluded that just doing that a few times is the fastest and easiest way to get it done. No need to climb under the car, deal with stuck drain plugs, or otherwise.

Regards,
