There is another school of thought regarding the use of distilled water in cooling systems.
Distilled water has no minerals, which on the surface sounds good. Who wants minerals in their cooling system, right?

The supposed problem is that distilled water is therefore 'hungry' for minerals, and it will need to get them from somewhere until it reaches a saturation point where no more minerals can be dissolved into suspension. These minerals will come from the metal components in your cooling system, such as your engine and radiator. Significant? Worse than calcium? Perhaps not...

I am curious if anyone has more data on this theory.
