The advice I've received from individuals as well as from the radiator
specialists is to never use distilled water in a radiator. Just use regular
water. My very unscientific understanding is that distilled water tries very
had
to become hard water, pulling extra molecules off the cooling system and
actually causing corrosion.
I've been using Water Wetter routinely in both the Healey and my race car
for years. Since it almost never freezes here, and radiator "coolant"
actually has less cooling capabilities than regular water and many versions are
super-poisonous to pets and little kids, even though they're sweet and taste
good, I don't use it in the Healey. And of course, since coolant is
superslick, we're not permitted to use it in the race cars. The WW, on the
other hand,
does improve cooling properties, which having additives that are good for
the water pump.
And if you don't believe it works, put two pans of water on the stove with
cooking thermometers in them, one with the appropriate proportion of WW and
one without and see what the water temperature is at when the water begins
to vaporize (i.e. "boil"). What the heck, run a third test with water with
"coolant" in it. See what the differences are. Report back to the class. (I
did this once for a magazine article -- felt like Dr. Science).
