Low conductivity = high resistance. They are inverse of each other. Pure water will dissolve your metals. Mineral water will cause galvanic corrosion. You can't win. That's why we add 40% ethylene glycol. It isn't there just for the freeze/boil protection! Personally I think the galvanic corrosion is a bigger issue. The aluminum intake on mine corroded to the iron head and allowed coolant to leak into the engine on my car. Proper coolant maintenance and driving the car regularly will prevent this from ever happening. |
