CHASSIS INFORMATION
Allow time for the oil to drain into the sump and start the engine. Observe
the engine for proper oil pressure. Run the engine at low idle for three
minutes while observing engine and filter for leaks. Stop the engine and
allow the oil to settle for five minutes. Check the level of the engine oil with
the dipstick. Correct the level as necessary.
• The recommended oil drain interval is defined by the API oil per-
formance classification and the engine duty cycle. Refer to the
OEM Engine 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
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
temperature 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 components. Under normal driving conditions, exiting the
highway is generally lighter engine operation and the need for the three to five
minutes is not necessary. It is recommended to fill the fuel tank at the end of the
day to help prevent condensation and drive out moist air. Do not fill the fuel
tank to the top, as fuel will expand when warm and may overflow.
