I would assume a 50/50 mix using distilled water?

And a good ground on the radiator/block to reduce the potential for electrolysis  BigGrin

Any other suggestions?

Sound good to me.  Coolant recovery system added to the list wouldn't hurt either.

Some of the anti Freeze makes are recommended fo aluminum. I'd read the bottle. Also the distilled water is an excellent idea. The metals and salts in tap water are 95% of the avenue electrolisis uses. Soft water is not distilled!

This brings up an alternate controversy: namely, the mineral-hungry nature of de-ionized water vs. distilled. This has never seemingly been made clear, as the different distilling processes may affect it. I'm not sure most commercial distilled water is totally mineral free? Many people have home reverse osmosis systems for drinking water, which is also never totally pure. It would be nice to finally get to the bottom of this. What really IS the proper water base, that most inhibits electrolysis, AND metal erosion?

Go with distilled water in your radiator and battery.

Soft water is a no-no. If it is softened by ion exchange it is taking out the calcium hardness in exchange for sodium that it puts in. Other method is lime softening, better but not good enough.
