Always dilute antifreeze to the correct
concentration based on freeze protection
before adding it to the cooling system.
Adding or using 100% antifreeze in a
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 coolant is above
ambient temperature or the en-
gine has not completely cooled.
The coolant level indicated on a
warmed system will be inaccu-
rate and can lead to low coolant
conditions during 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.
NOTE
The pressure cap (on the side of
the surge tank) should NEVER
be removed. The fill cap (On the
top, not the side of the surge
tank) is the correct fill point.
Aftertreatment Exhaust Piping
Daily and refueling maintenance check for
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
Daily and refueling maintenance check for
engine 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.
