2-32. OPERATION IN EXTREME COLD (cont)
Batteries. Have unit maintenance personnel check the electrolyte and add distilled water (item 4, app E), if
necessary, to 1/8 inch (3.2 mm) below the bottom of the cover filling tubes. Check and add water just before the
locomotive goes into service, so the water will have time to mix with the electrolyte before locomotive shutdown.
Starting. Heating of water jacket and crankcase oil, and/or use of extra battery capacity may be required to
assist starting in extreme cold. Connect water jacket heater cable as follows:
Connect female connector into water jacket heater receptacle.
Connect male connector into 240 v power source.
Heat water until water temperature reaches 50F (10C).
If the engine is to be shut down and the cooling system is not adequately protected with antifreeze solution,
the entire system will have to be drained.
When the locomotive is to be shut down for an extended period in freezing weather, have unit
maintenance personnel check the specific gravity of the batteries (para 4-30). Fully charged batteries can
withstand temperatures as low as -35°F (-37C). Unit maintenance personnel must take hydrometer
2-33. OPERATION IN DUSTY OR SANDY AREAS
Operation in dusty or sandy areas requires more frequent cleaning and servicing of filters to prevent dust entering
engine, air compressor, generator, traction motors, and fuel system. Dust buildup on major components increases
chance of entry into internal areas, and interferes with adequate cooling. Pay particular attention to the following service
areas: a. Lubrication.
Refer to LO 55-2210-223-12. Shorten service interval as required.
Clean areas around lubrication fittings, fill ports, dip sticks, breathers, and filters before servicing or
Have unit maintenance personnel service engine oil filter and fuel filters frequently.
Cooling System. Perform the following procedures:
(1) Keep radiator clean and free of dirt and debris. Keep shutters open to the maximum.
Check hose connections for leaks.
Check for debris, dust, and sand clogging radiator fins.
