I have read this thread with interest and understand the nominal cost of distilled water. Therefore cost is not a factor and who would dispute the manufacturer for specifying distilled water? However, I obtained the water quality report for our community and it reads similar to an used oil analysis. Five elements were just a few parts per billion. Total dissolved solids were just 180 parts per million. Alkalinity was 50 parts per million, calcium just 4 grains, sodium 15 ppm, ammonia 0.01 ppm. I am not understanding how trace amounts in the few parts per billion, or few parts per million can make a significant difference? I suspect the antifreeze coolant is more subject to contamination by the internal water passages, freeze plugs, gaskets, gasket sealers, thermostat components, water pump components, and cooling system hoses. Despite my doubts, used distilled water last flush and fill.
