Page 68
Check and replenish engine coolant
through an access door located at
the rear, above the radiator
compartment door, on the roadside
of the vehicle.
1. Before opening the filler cap,
release the pressure by
pushing up on the pressure
release valve button. Hold
button until all pressure is
released.
2. With a clean rag over the surge
tank handle, slowly pull handle.
3. When all pressure has
dissipated, release the safety
tab and pull back the surge tank
handle completely.
4. Add coolant until the correct
level is shown on the sight
gauge of the surge tank.
High Coolant
Temperature
Engine shutdown will occur if
coolant exceeds normal operating
temperature.
Wait until boiling has stopped and
the engine is cool, before adding
coolant.
Low Engine Coolant
Level
The vehicle is equipped with a
warning system designed to indicate
a low coolant level in the cooling
system.
A loss of coolant or if the coolant
level falls below the probe assembly
in the surge tank, the CHECK
ENGINE indicator will illuminate,
and an audible alarm will sound.
After 30 seconds the STOP
ENGINE indicator will illuminate and
the engine will then automatically
begin shutdown sequence. The
operator should move the vehicle to
a safe location and shutdown the
vehicle.
CAUTION !
If the cooling system is frozen,
do not operate the engine. Notify
maintenance personnel if water
was added to system while on a
run during freezing weather. A
frozen cooling system can cause
equipment damage.
