OPERATE IN EXTREME COLD
a. Extreme cold causes many problems:
Batteries may freeze or lose their electrical efficiency.
Various materials will become hard, brittle, and easily damaged.
The cooling system requires adequate protection from extreme cold.
Fuels, lubricants, and antifreeze compounds require special storage, handling, and use.
b. Refer to FM 9-207 for additional information.
Notify Organizational Maintenance to prepare vehicle for arctic operation.
c. Vehicles assigned to arctic regions are equipped with an auxiliary arctic heater to enable easier starting by providing
preheating of engine cooling system.
d. When starting out in extreme cold, follow these procedures:
Be careful when you first start your vehicle. Use cold weather starting procedure (WP 0005 00-2) and
allow engine time to reach operating temperature range of 180 to 200F (82 to 93C). Be alert that tires
may be frozen to ground.
Start driving very slowly for about 100 yd (91.4 m). If a problem is noted, notify Organizational Mainte-
nance as required.
e. When parking, follow these procedures:
If vehicle will be parked for a short period, park in a sheltered area out of wind. If shelter is not available,
park vehicle so right side, where radiator is located, does not face into the wind.
If vehicle will be parked for a long shutdown period, try to park on high ground and use planks or brush to
make a raised and relatively dry surface. Keep tires out of snow, water, ice, and mud, if possible.
Clean snow, ice, and mud from vehicle as soon as possible after shutdown.
If vehicle will be parked for a long period of time, have Organizational Maintenance remove and store bat-
teries. Fill fuel tank to guard against condensation and drain any accumulated water from air reservoirs and
Ensure tires are properly inflated.
