cooling system may result in cooling
system plugging and overheating
problems.
This procedure should be followed as part
of daily and refueling maintenance checks.
Perform the following steps to check the
coolant level:
1. Check that vehicle is a on a level
surface.
2. Ensure engine has not been run for
several hours.
CAUTION
Due to thermal expansion the coolant
level CANNOT be checked if the cool-
ant is above ambient temperature or
the engine has not completely cooled.
The coolant level indicated on a
warmed system will be inaccurate and
can lead to low coolant conditions dur-
ing cold-starts.
3. Check coolant level. It should be
visible through the clear plastic
surge tank.
4. Add coolant as necessary until
proper level is reached; see special
fill instruction if filling from empty.
NOTE
The pressure cap (on the rear-top of
the surge tank) should NEVER be re-
moved. The fill cap (on the ergonomic
fill neck, not on the the surge tank) is
the correct fill point.
Aftertreatment Exhaust Piping
This procedure should be followed as part
of daily and refueling maintenance checks.
1. Inspect for cracks.
2. Inspect for clearance to other
components (i.e. electrical
harnesses, etc.).
3. Inspect hose/pipe condition –
deterioration/signs of leaking.
Air Intake Piping
This procedure should be followed as part
of daily and refueling maintenance checks.
1. Inspect hose/pipe condition –
deterioration/signs of leaking.
2. Inspect hose clamps for tightness
and pinching/cutting of hoses.
3. Inspect clearance to other
components.
4. Check air restriction gauge.
How to Drain Moisture from Air
Tank
1. Locate the various air tanks on the
vehicle
2. On the air tank, look for a valve,
typically on the bottom of the tank.
3. To eject moisture from the air
system tanks, pull the line that is
connected to the moisture ejection
valve.
4. Continue pulling until the air comes
out free of water.
Diesel Exhaust Fluid
This procedure should be followed as part
of daily and refueling maintenance checks.
1. Check level of diesel exhaust fluid.
