CHASSIS INFORMATION — 10
Oil additives should not be used unless
the oil supplier or oil manufacturer has been
consulted and provided positive evidence or
data establishing satisfactory performance in
the engine.
NOTE:
The engine does not require a “break-
in” procedure.
INFORMATION:
Refer to the Engine Manufacturers
Owners Manual for details on the oil
maintenance schedule.
NOTE:
The engine is filled with Texaco Ursa
Premium TDX EC SAE 15-40w (with API
CJ-4 rating) multi-viscosity oil from the
factory.
ENGINE SHUTDOWN
Allow the engine to idle three to ve 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 ve minutes is not necessary.
Extended Engine Shutdown
Verify that all the uid levels are correct
when the motorhome has been sitting for
30 days or more. 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
engine manufacturer’s owner’s manual for
guidelines on troubleshooting low oil pressure,
or contact a qualied service technician. Allow
the engine to idle for ve minutes before
operating under a load.
COOLANT SYSTEM
A fully formulated coolant is recommended to
simplify cooling system maintenance. Coolant
that is fully formulated contains balanced
amounts of antifreeze, Supplemental Coolant
Additive (SCA), buffering compounds and
clean, quality water.
Antifreeze that is not fully formulated must
be mixed with clean, quality water (distilled
water preferred) in a 50/50 ratio (40 to 60%
working range).
This ratio will provide protection from -34º F.
to 228º F. Antifreeze must be of low silicate
content as dened by ASTM D-4985. The 50/50
ratio of antifreeze and clean quality water plus
SCA must be premixed prior to being put in
the cooling system. Placing antifreeze and then
water in the cooling system is not recommended.
Refer to the OEM engine manual for more
information.
CAUTION:
An over-concentration of antifreeze
will reduce freeze protection. Use of
high silicate antifreeze can damage the
cooling system. SCA is required in the
cooling system to inhibit cylinder liner
pitting as a result of cavitation erosion.
WARNING:
DO NOT continue engine operation if
engine temperature rises above 220º F. At
approximately 225º F., the Warning light
on the dash will illuminate and the engine
protection software will begin to decrease
fuel (derate) to the engine regardless of
throttle position. Continued operation
will result in severe engine damage.
Check the coolant level before each trip and
when checking the oil level. Coolant freeze
point is checked at every oil change interval
or as specied by the engine manufacturer.
Coolant drain and ush intervals are specied
by the engine manufacturer. Refer to the OEM
engine manual for more information on service
maintenance intervals.
INFORMATION:
Refer to the engine OEM manual for
details on engine coolant maintenance.
