The hitch(es) above are that unless your car exposed to a hard freeze--two consecutive nights 30 or below -- or has air conditioning even in Phoenix in August, avoid antifreeze like the plague.

And according to an article by a Chrysler engineer member of the Auburn-Cord-Duesenberg Club in their newsletter some years ago, soluble oil is a long outmoded, inadvisable practice, like antifreeze leaving heat transfer inhibiting film on cooling system passages. Neither do you require "water pump lubricant." As a patent-generating industrial chemist friend who worked on cars when young pointed out, "water itself is a good lubricant," in such situation.

You're best served by using reverse osmosis water (read the label, do not buy unless you see that phrase), which is also available for 49 cents a gallon at any Whole Foods, with a good rust/corrosion inhibitor. I like No-Rosion Coolant Corrosion Inhibitor, originally produced to protect titanically expensive industrial cooling towers from their internal hellish conditions, but Red Line's Water Wetter is also good. For all the info you need on cooling system preservation, see the tech info link on www.no-rosion.com

As No-Rosion explains, never use distilled water.

There's a wealth of information on your car, Mike, via the provided search box on the upper right corner of this site's homepage, as well as the provided Literature Archive and Factory Service Index tabs under Main Menu to the left.

There are several sources of inexpensive reproductions of your '37's shop manual, the most important automotive book you can have.

As a longtime friend who's owned 70+ Packards, junior and senior, since he in high school, i upon trike, reminds, the goal should always be "factory standard."

Packard never built a better car at any price than your One Twenty.
