Military Specification MIL-C-11755 Arctic type, nonvolatile antifreeze compound is intended for use in the cooling system
of liquid-cooled internal combustion engines. It is used for protection against freezing primarily in Arctic regions where
ambient temperature remains for extended periods close to -40 F (-40C) or drops below, to as low as -90F (-68C).
3
Use an accurate hydrometer. To test hydrometer, use 1 part ethylene glycol antifreeze to 2 parts water. This should
produce a hydrometer reading 0F (-17.8C).
NOTE: Fasten a tag near the radiator filler cap indicating the type antifreeze.
