Jim,
The zinc and magnesium just dissolves into ions, just like your aluminum, and
doesn't come back out unless you throw some pretty strange reactive chemical in.
It will remain in solution an will drain out with the next coolant change. I
agree about flushing, no matter what you do. Once a year is best, once every
two
years if you add a lubricant for the pump after 12 months, and certainly change
everything, including a new sacrificial anode if it disappears and the chain is
still there ({9->.
Of course, Southern California doesn't worry to much about freezing (except for
the skiers), and Bob has a point about running all distilled water with pump
lubricant for this weather. The boiling point, with 13-14 psi cap, isn't much
different than the antifreeze, and it is a better conductor of heat. (Cheaper
too). Freezing point is another story, but we are both in sun country.
