Contrary to popular belief, destilled water is NOT good for cooling
systems.  During the distilling process:
 
Many people have "heard" distilled water is best to use in a cooling
system.  This is WRONG.  While it certainly is true that distilled
water's purity prevents electrolysis and scale/deposit formation, it
unfortunately comes with a potentially very damaging side effect.
During the distillation process, water is vaporized into it's gaseous
phase, so all impurities are left behind.  These impurities include a
number of minerals, including calcium and magnesium - the two components
of "hardness."  The water is then condensed back into it's liquid phase,
so the resulting liquid is pure water - in fact, some of the purest
water on earth.  The problem is that when water is distilled, or
"stripped" of impurities, the resulting solution is composed of
chemically imbalanced "ions."  This leaves distilled water
"electrochemically hungry," so it will actually strip electrons from the
metals in a cooling system as it attempts to chemically re-balance
itself.  As it chemically removes electrons from the cooling system
metals, it does damage that will eventually lead to leaks and system
failure.  Using distilled water in combination with antifreeze tends to
lessen this effect, as the distilled water will seek and find
electrochemical balance from the various chemical ingredients in the
antifreeze mixture.  However, there is still risk involved. 
 
This is off of the no-rosion web site FAQ's ( www.norosion.com)  I have
has numerous conversations with the manufacturer. The best thing to use
is regular tap water with a corrosion inhibitor unless you need the cold
weather anti freezing protection.  No Rosion is the only additive that
provides 100% corrosion protection with 100% plain tap water.
