The Three Wise Men above are this wonderful site's savviest. I could add nothing other than Simi Valley not subject to freezing temperature so your engine better served by just straight, soft water and a good quality rust and corrosion inhibitor. Have no knowledge of the inhibitor recommended by Cummins for Diesel engines, but have for decades used either Red Line Rust & Corrosion Inhibitor, and
since 1995, No-Rosion Cooling System Corrosion Inhibitor (no-rosion.com).
Under no circumstances use distilled water, which is ion-hungry and leaches minerals (like lead and solder from your radiator). Soft water is fine, and your engine will run cooler in the bargain. Antifreeze also seeps where water will not, another drawback in a vintage engine.

Antifreeze degrades over time and leaves a heat-transfer-inhibiting film on your cooling system walls, as does soluble oil, an outmoded practice.

For more information, visit No-Rosion's website, click on the tech info tab. And no, I don't work for nor have stock in No-Rosion. But when I find products that help preserve our wheeled alter egos, I sing their praises.
