Section IV. OPERATION UNDER SENSUAL -CONDITIONS
28. Extreme Cold (Below Freezing)
a. General. Take special precautions and provide extra servicing necessary to maintain the operation of the
pumping unit in subfreezing temperatures.
b. Fuel System Keep the fuel tank as full as possible to keep water in the air from condensing in the fuel tank.
Use the fuel primer pump to keep the fuel system free of air pockets and to decrease the chance of ice formation in the
fuel system. Service the fuel sediment bowl and fuel strainer daily (pare 58a).
c. Lubrication Lubricate the pumping unit as directed in the current lubrication order (fig. 14).
d. Coolant System Maintain a proper amount of antifreeze in the engine coolant. Refer to table I for the correct
antifreeze mixture. Before in stalling antifreeze, clean and flush the coolant system as directed in paragraph 76. Check
carefully for coolant leaks.
e. Electrical System Keep electrical components free of ice and moisture. Avoid unnecessary handling of
electrical wiring during extreme cold. Wiring becomes brittle and is easily damaged and cracked. Maintain the batteries
at full charge to
