"and definitely don't use deionized water which will quickly exhaust the buffering capacity of the coolant and start stripping metals."

Could you elaborate on this a little?

I looked it up and found that deionized water is obtained by running water through a charged resin bed. That is the way house water softeners work. The resin bed attracts the ions (both positive and negative) leaving only water.
It is said by the manufacturers that the water is suitable for use in cooling systems, both industrial and car radiators.

Demineralized water had the the ions removed by filtering.
Distilled water had the the ions removed by evaporating and condensing the water, leaving the minerals (ions) behind.

My question: why would this water react with the coolant differently from demineralized or distilled water?
