"Just don't use plain water"
That's interesting, because it's hard to define plain water, being from different countries and all. Tap water, and rain water would be different.
yes, thats true. if i say "plain water" i mean the tap water over here (has to be of much better quality than most bottled drinking waters over here)

But distilled water should be fine, as it does not conduct electricity well at all. So the electrons should not leave the aluminium. Electrons leaving the aluminium (or any metal) is a process called 'oxidation'. And the Aluminium ions (which are now ions, not aluminium metal) would flow through the electrolyte, leaving a radiator with less and less metal until it leaks, falls appart etc. But this wouldn't happen as distilled water is a poor conductor of electricity, hence isn't an electrolyte? How is coolant for conducting? Also in an electrolytic cell you usually use a solution containing the ions you want to oxidise or reduce as the electrolyte.
This is equally a questions as it is a statement.
i am not sure about distilled water without coolant, i know it will corrode less than with non-distilled water, but it still does (tested with a summer-only car). only distilled water with some coolant kept the system clean (and lubed the waterpump), but don't ask me why
