[DeTomaso] radiator

[Yogi, Dennis]

Not to say it causes harm directly.  What its doing is starting to
deplete the antifreeze/anti corrosive of its active chemicals
immediately after mixing so the additives have shorter effective life
spans and less corrosion protection.  This is just a fact of chemistry,
distilled water loses minerals during the process and will seek to
replace them from the coolant additives and metals to balance itself.
Most people will service their cooling systems adding distilled water
with their anti corrosive mixes and figure that they're good for another
year or more.  The distilled water in turn will be depleting the anti
corrosive additives shortening their coolant's lifespan and anti
corrosive properties which could lead to corrosion damage.

Been using distilled water for years with no leaks, no drips and no
errors.
Hard to believe H2O is bad.  The PH can tend to be slightly less than
neutral but, not low enough to cause any real harm.  Used with a proper
corrosion inhibitor it should provide years of great service.  IMHO.

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.
