SUBSTANCE

Maximum protection is obtained at 60 percent by volume (4.8 pints of ethylene glycol per gallon of solution)

Military Specification MIL-C-11755 Arctic type, nonvolatile anti-freeze 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 the ambient

temperature remains for extended period close to -40F or drops below, to as low as -90F.

Use an accurate hydrometer. To test hydrometer, use 1 part ethylene glycol to 2 parts water. This should produce a hydrometer

reading of 0F.

NOTE

Fasten a tag near the radiator filler cap indicating the type antifreeze used.
