Operation
CAUTION
To prevent property damage, if the coolant should
get extremely low and the engine very hot, let the
engine cool for approximately 15 minutes before
adding coolant. Then, add coolant slowly with
the engine running. Adding cold coolant to a hot
engine may crack the cylinder head or crankcase.
Never use water alone.
For vehicles with MaxxForce
®
11, 13, 15 or Navistar
®
N13
engines, the cooling system is filled at the factory with Nitrite-free
Shell Rotella
®
Ultra ELC.
For vehicles with Cummins
®
ISX15 engine, the cooling system
is filled at the factory with Shell Rotella
®
ELC (Red) coolant.
Navistar, Inc. recommends using only the approved coolant with
the 2010 cooling packages, and will not warrant these cooling
systems that have not utilized the recommended coolant.
The label on the deaeration tank provides additional coolant
/ antifreeze information.
Consult the Engine Operation and
Maintenance Manual for coolant service life details.
Engine Oil
Keep oil level between the ADD and FULL marks. Never operate
an engine with oil level below the ADD mark.
To obtain an accurate engine oil level reading the vehicle must
be parked on a level surface with the engine off for at least 15
minutes before checking the oil level. This will ensure the oil
is level in the oil pan and the circulated oil has had a chance to
return to the pan. It is not necessary for the oil to be hot to obtain
an accurate reading.
When checking the oil level, the dipstick must be withdrawn and
wiped clean, then inserted all the way and again withdrawn for
a true check.
Use only recommended viscosity engine oil. Refer to the Engine
Operation and Maintenance Manual for engine oil specifications
and proper oil choice.
The lubricating oil in a diesel engine becomes dark in color
after short periods of engine operation. This discoloration is not
harmful to engine parts as long as the oil and oil filter element
changes are performed at recommended intervals.
Engine Performance Problems
•
Low engine power can be the result of a plugged fuel filter.
Fuel filters can plug prematurely due to the use of fuel that
is contaminated with a high amount of sediment, microbial
growth, or water. Fuel that has been stored for longer
periods of time may also reduce engine performance.
•
Failure to maintain the vehicle as required in the
Maintenance Instructions and Maintenance Intervals and
Specifications sections of this manual, as well as any
separately available Engine Operation and Maintenance
Manual, can cause engine performance problems.
Too low of a cetane number could cause hard starting and
slower warm-up and could increase engine noise and exhaust
emissions.
