water, pure water (distilled), does not conduct electricity, but acts as an insulator, so would this help to prevent corrosion through electrolysis??? I don't know what happens when the coolant is added... whether it makes water conductive as does salt... so maybe distilled water, dexcool (orange is a nice color), and water wetter... (does it come in a color?)... and a little fish. >From: michael schiesser <drschiesser@bigplanet.com> > >Do you guys recc using special water like distilled or denatured to lower >the mineral content? > >----- Original Message ----- >From: John Rodgers <inua@hiwaay.net> > > > > Michael, > > > > Running 100% coolant is to me a terrible idea.
