I did try to word it as such - actually I always just blend distilled water
50/50 with anti-freeze and use that for my coolant as well as to top up my
coolant level.
As for Barney's statement on the distilled water affinity, he is once again
all-wise. Distilled water as well as low mineral water is actually more
corrosive because it has more ability to absorb or dissolve metals and
minerals. In addition, absorption of carbon dioxide causes a reduction of
pH (acidity). Drinking water suppliers use an index to determine
corrosivity (Langolier index I believe) and very clean water will show a
high corrosivity. Thus it is often adjusted by adding additional chemicals
particularly to insure that the drinking water is less likely to absorb
copper and lead from old pipes.
I could dig up documentation but I'm sure most of you have a minimal
interest. In short, mix distilled water (or other low mineral water) with
anti-freeze (with its anti-corrosive chemicals) and you'll be in good shape.
