OPERATE IN EXTREME COLD
Extreme cold causes many problems:
Lubricants thicken or congeal.
Batteries may freeze or lose their electrical efficiency.
Fuel may not readily atomize for combustion.
Various materials become hard, brittle, and easily damaged.
Cooling system requires adequate protection from extreme cold.
Fuels, lubricants, and antifreeze compounds require special storage, han-
dling, and use.
Refer to FM 9-207 for additional information.
All vehicles assigned to arctic regions are equipped with an auxiliary arctic heater
kit to protect vehicle systems from freeze damage, enables easier starting by provid-
ing engine block preheating, and boosts cab heat output. Refer to subparagraphs 2
and 3 for operation of arctic heater.
When starting out:
Be careful when you first start your vehicle. Use cold weather starting pro-
cedure and allow engine time to reach operating temperature range of 120-
140°F (48-59°C). Be alert that tires may be frozen to ground.
