CAUTION
Do not direct high pressure water onto
seals or flexible hoses. Water may en-
ter the part which will contaminate the
system lubricants and fluids. To pre-
vent damage to these components,
keep a gentle flow of water moving at
all times. Failure to comply may result
in equipment damage.
Daily or Refueling Maintenance
Checks
Fuel Filter / Water Separator
This procedure should be followed as part
of daily and refueling maintenance checks.
1. Drain trapped water (if equipped).
Refer to the Fuel Filter Water
Draining Procedure.
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.
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.
Cooling Fan
This procedure should be followed as part
of daily and refueling maintenance checks.
1. Inspect for cracks.
2. Inspect for clearance to other
components.
Coolant Level
Replacement or top up coolant should
have the same antifreeze concentration
and corrosion inhibitor content as the
original coolant in the cooling system. If
operating in sub-freezing conditions, a
60/40 mix of antifreeze and distilled water
may be substituted.
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 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.
