To add one small nugget to Marshalls excellent instructions, turn the heater
control to full hot - and leave it there until finished with the whole

to do so can allow a bubble to form that will not be flushed out and irratic
temps will occur.
Good luck with your Citric flush - I plan to try it myself during the next
year or so.
And one more caveat for those of us plagued with ACC2 servos - you really should
bypass the servo's coolant passages for a coolant flush. That is, if you'd like
your servo to continue functioning (if it is at all)...
