Military Specification MIL-C 11755 Arctic type, nonvolatile antifreeze compound is intended for use in the cooling system of liquid-cooled internal combustion
engines for protection against freezing primarily in Arctic regions where the ambient temperature remains for extended periods of time close to -40F. or drops
below, to a low as -90F.

Use an accurate hydrometer. To test hydrometer, use 1 part ethylene glycol antifreeze to 2 parts water. This should produce a hydrometer reading of 0F.
Note. Fasten a tag near the radiator filler cap indicating the types of antifreeze.
