Routine Maintenance Recommendations:
1. Check oil level daily.
2. Replace oil filter at every oil drain interval.
3. Cummins Engine Company, Inc. recommends the use of high quality,
API (American Petroleum Institute) licensed CH-4 or CES20071,
15W-40, multiviscosity oil or premium oil.
4. The recommended oil drain interval is defined by the API oil perform-
ance classification and the engine duty cycle. Refer to the Cummins
Operation and Maintenance Manual for complete details.
It is possible to operate diesel engines in extremely cold environments.
The engine should be properly prepared and maintained. The correct lubri-
cants, 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: Winterize and Arctic.
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
meeting 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.
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 gener-
ally lighter engine operation and the need for the 3 to 5 minutes is not neces-
sary.
