installation and replenishment of losses.
DO NOT DILUTE WITH WATER OR ANY
Maximum protection is obtained at 60 percent by volume [4.8 pints (2.27 liters) of ethylene glycol per gallon (3.785 liters)
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).
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.
