Coolant Temperature Gauge
NOTICE
A sudden increase in coolant temperature may
indicate engine or cooling system failure. Bring
the vehicle to a safe stop and investigate the
cause to prevent further damage. Do not operate
the engine until the cause has been determined
and corrected.
During normal engine operation, the coolant tem-
perature gauge should read 175 to 195°F (79 to
91°C). If the temperature remains below 160°F
(71°C), inspect the cooling system to determine the
cause.
If coolant temperature rises above the maximum
temperature listed in
Table 4.3, the CHECK engine
lamp will illuminate. If the condition does not im-
prove, the STOP engine lamp will also illuminate and
an audible warning will sound. The engine will then
derate or shut down, depending on the type of en-
gine protection system installed.
Maximum Coolant Temperature
Engine Make Temperature: °F (°C)
Cummins 225 (107)
Detroit 215 (101)
Mercedes-Benz 221 (105)

Drive Axle Oil Temperature Gauges
NOTICE
A sudden increase in oil temperature that is not
caused by a load increase may indicate mechani-
cal failure. Bring the vehicle to a safe stop and
investigate the cause to prevent further damage.
Do not operate the vehicle until the cause has
been determined and corrected.
During normal operation, drive axle oil temperature
gauges should read as follows:
160 to 220°F (71 to 104°C) for Detroit
and
Meritor
drive axles
180 to 200°F (82 to 93°C) for Dana Spicer®
drive axles
Under heavy loads, such as when climbing steep
grades, temperatures that exceed the normal oil tem-
perature range for a short period are not unusual. If
the temperature returns to normal when the load de-
creases, there is no problem.
Engine Oil Pressure Gauge
NOTICE
A sudden decrease or absence of oil pressure
may indicate mechanical failure. Bring the vehicle
to a safe stop and investigate the cause to pre-
vent further damage. Do not operate the engine
until the cause has been determined and cor-
rected.
The engine oil pressure gauge displays the current
engine oil pressure. If engine oil pressure falls below
the minimum levels shown in
Table 4.4, the CHECK
engine lamp will illuminate. If the condition does not
improve, the STOP engine lamp will also illuminate
and an audible warning will sound. The engine will
then derate or shut down, depending on the type of
engine protection system installed.
Minimum Oil Pressure

At Rated RPM:

Cummins 15 (103) 35 (241)
Detroit 14 (97) 55 (350)
Mercedes-Benz 7 (50) 36 (250)

Oil pressures are given with the engine at operating temperature. With
the engine cold, oil pressure may be higher. Individual engines may vary
from the listed pressures; observe and record pressures when the engine
is new to create a guide for checking engine condition.
