yes, I believe the question was, how to do this :-)  I believe the
Bentley does cover this part, Will.  There are no plugs etc, just
gotta pull a few hoses.

set the CC system to any mode and punch the temp all the way to HI to
guarantee the heater valve will be opened.

Well...carefully.  Here, the water pressure(60+psi) is plenty enough
to do some serious damage to the cooling system.

BTW Will, there are two schools of thought with the various radiator
flush solutions.  One school says "don't, you'll cause leaks" and the
other school says "yes, do it, it cleans things up, and if it causes
a leak, well, that was going to leak anyway, just a matter of time."
