It is possible to operate diesel engines in extremely cold environments. The
engine should be properly prepared and maintained. The correct lubricants, fuels
and coolant MUST be used for the cold weather range for which the motor home
is being operated. Cold weather operation can be defined in two categories:
Winterize and Arctic.
Ether as a cold weather started aide may be used only with the ISM
engine. Do not use excessive amount when starting the engine. Damage will
occur
NOTE: Refer to the Operations and Maintenance Manual for more detailed
information.
WINTERIZE (32º to -25º F) (0º to -32º C)
Use a 50 antifreeze / 50 water coolant mixture, use multi-viscosity oil meet-
ing Cummins specifications, and fuel to have maximum cloud pour points 10º F
(6º C) lower than the ambient temperature in which the motor home operates.
ARCTIC (-25º to -65º F) (-32º to -52º C)
Use a 60 percent antifreeze / 40 water coolant mixture, use oil meeting
Cummins specifications, and fuel to have maximum cloud pour points 10º F (6º
C) lower than the ambient temperature in which the motorhome operates.
The engine block heater may need to be plugged in 2 to 3 hours prior to start-
ing. The engine block heater is rated at 1500 watts, 110 volts AC and requires
the motorhome be plugged into shore power or have the generator running. It is
not necessary to leave the block heater plugged in for long periods of time. The
block heater requires about 13 amps to operate.
When the motorhome has been sitting for extended periods, 30 days or more,
verify all the fluid levels are correct. Follow the normal starting procedures. If
the oil pressure gauge does not register within 15 seconds, shut off the engine
immediately to avoid damage. Consult the Cummins Operations and
Maintenance Manual for guidelines on troubleshooting low oil pressure, or con-
tact a qualified service technician. Allow the engine to idle for 3 to 5 minutes
before operating under a load.
General guidelines for shutting the engine down are fairly simplistic. Allow
the engine to idle 3 to 5 minutes after a full load operation. This allows adequate
cool down of pistons, cylinders, bearings and turbocharger components. Under
normal driving conditions, exiting the highway is generally lighter engine opera-
tion and the need for the 3 to 5 minutes is not necessary.
