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
motorhome is being operated. Cold weather operation can be defined in two
categories:
Winter
and
Arctic
.
WINTER
(32º to -25º F) (0º to -32º C): Use a 50% antifreeze to 50% water
coolant mixture, use multi-viscosity 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.
ARCTIC
(-25º to -65º F) (-32º to -52º C): Use a 60% antifreeze to 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 tempera-
ture in which the motorhome operates.
Refer to the Operations & Maintenance Manual for more
detailed information.
General guidelines for shutting the engine down are fairly simplistic. Allow
the engine to idle three to five minutes after a full load operation. This allows
adequate cool down of pistons, cylinders, bearings and turbocharger compo-
nents. Under normal driving conditions, exiting the highway is generally
lighter engine operation and the need for the three to five minutes is not neces-
sary.
When the motorhome has been sitting for extended periods, 30 days or
more, verify all the fluid levels are correct. Follow the normal starting proce-
dures. If the oil pressure gauge does not register within 15 seconds, shut off the
engine immediately to avoid damage. Consult the Cummins Operation &
Maintenance Manual for guidelines on troubleshooting low oil pressure, or
contact a qualified service technician. Allow the engine to idle for three to five
minutes before operating under a load.
