<p>To be totally a-retentive, water is called the 'Universal
Solvent' because it will dissolve many <i>inorganic</i>
compounds--esp. 'salts'--as they are polar compounds (one side of
the molecule is positive, and one side is negative, and the H+/OH-
ions in water will 'pull' the salt apart into its constituent ions
and dissolve it). Water is a particularly lousy solvent of
organic (non-polar) compounds; try mixing vegetable or motor oil
with it sometime.</p>
<p><br>
</p>
<p>Water is not an oxidizing agent--it is the product of an
oxidation/reduction reaction itself between hydrogen and
oxygen--but when it has polar salts dissolved in it it does
conduct current, which facilitates oxidation-reduction reactions
(e.g. 'rust'). Distilled water will dissolve more salts than
(most) tap water, as the tap water is already further along in
saturation. I've heard people say distilled water is 'ion
hungry,' which, for the life of me I don't understand (unless they
mean it will dissolve a bigger pile of salt than really hard
water, which is true).<br>

I have to agree with the theory that grounding can affect an
alloy radiator. If you have a problem with corrosion despite
using corrosion inhibitors then the problem is not the fluid
component of the system it is more likely electrolytic
corrosion. Maybe the problem isn't engine to chassis grounding,
but radiator to chassis grounding. It sounds like some effort
needs to be made to isolate the radiator (electrically) from the
chassis. or to neutralize the electrolytic forces in the
system. </div>

Either keeping the radiator out of the electrical loop or
assuring it is on the cathode side seems to be a good idea since
aluminum is much lower on the noble scale than iron. In a
positive ground system the chassis is the anode and if the
radiator is grounded to the chassis it will also be an anode and
will thus be subject to electrolytic corrosion. (The anode,
positive pole, in any circuit gives up electrons which carry the
electrical current. Loss of large numbers of electrons weakens
the atomic structure of anode material and causes it to break
down or corrode.)</div>

I don't think that distilled water is necessary and as a matter
of fact distilled water should be considered more corrosive than
tap water. Water has the propensity to oxidize most other types
of materials (universal solvent and all that) and distilled
water has more of that propensity than harder water because in
that case it has been partially saturated by dissolved minerals.
The argument for distilled water is that it carries no calcium
or other minerals into the cooling system which might eventually
foul the heat exchange surfaces. That is a minor danger and
would only be a problem if you were adding large volumes of
water on a regular basis. If your cooling system is tight it
should never be a problem.</div>

am having difficulty with the logic.

adequately grounded and a ground of sufficient size to
operate a starter will definitely be big enough to eliminate
any EMF difference between the engine and the chassis. </div>

Water. I discussed this comment with my
German/American friend who was installing a aluminum
radiator in his Lagonda Drop Head Coup. He has
owned various European Vehicles with aluminum
radiators, and classic cars with aluminum
radiators. He cannot understand the need for
distilled water if you are using antifreeze which
includes anti-corrosion additives or using such
additive separately. Furthermore, the biggest
problem with alloy radiators is the matter of a good
grounded engine. His experience the failure of the
alloy radiator is a poorly grounded engine which
causes the electric current to run to ground via the
water in coolant system hence destroy the aluminum
being dissimilar metal. So check the soundness of
the ground.</span></p>
