CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to an
oil leak and engine damage.7. Fill the new filter with clean engine oil.
8. Coat the gasket on the new filter with clean engine oil.
9. Screw on the oil filter until a slight resistance is felt, then tighten an additional 3/4 turn.
10. Start the engine and check for leakage around the oil filter. Correct as required.
11. Install skid plate in reverse order of removal.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
oil if necessary.
CAUTION
Your vehicle may require more frequent
maintenance if it operates on biodiesel
blends between 6% and 10% (B6 and B10) .
To avoid damage to your vehicle, the oil,
oil filter, and fuel filter will need to be
replaced after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion in the “Titan Owner’s Manual.”
FUEL FILTER REPLACEMENT (stage
1)
NOTE:
● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system.

●If the “Low Fuel Pressure Service Fuel
System” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle and restart the vehicle. If the mes-
sage is still displayed or the Malfunc-
tion Indicator Light is illuminated after
a full key cycle , it is recommended that
you visit a NISSAN dealer for service.
WARNING
● The fuel system (fuel pump, high pres-
sure fuel lines, fuel rail, injectors) con-
tain very high pressure fuel. To avoid the
risk of personal injury or fire;
– Do not loosen any fittings while the engine is running.
– Wait at least 10 minutes after shut- ting down the engine before loosen-
ing any fittings in the high-pressure
fuel system to allow pressure to de-
crease to a lower level.
– Wear appropriate eye protection and protective equipment as high-
pressure fuel spray can penetrate the
skin. – Never smoke or allow sparks or
flames (such as pilot lights, electrical
switches, or welding equipment) in
the work area. Never allow diesel fuel
to spill onto a hot exhaust manifold
which can cause a fire.
● Depending on the circumstance, diesel
fuel is flammable. When inspecting or
performing service or repairs on the fuel
system, to reduce the possibility of fire
and resulting severe personal injury,
death, or property damage, never
smoke or allow sparks or flames (such
as pilot lights, electrical switches, or
welding equipment) in the work area.
● Do not vent the fuel system on a hot
engine; this can cause fuel to spill onto
a hot exhaust manifold, which can
cause a fire.
● Batteries can emit explosive gases. To
reduce the possibility of personal injury,
always ventilate the compartment be-
fore servicing the batteries. To reduce
the possibility of arcing, remove the
negative (-) battery cable first and at-
tach the negative (-) battery cable last. ●
When using a steam cleaner, wear
safety glasses or a face shield, as well
as protective clothing. Hot steam can
cause serious personal injury.
● Wear appropriate eye and face protec-
tion when using compressed air. Flying
debris and dirt can cause personal
injury.
CAUTION
Clean all around the filter area before dis-
assembly. Dirt or contaminants can dam-
age the fuel system.

you visit a NISSAN dealer for service.
● For additional information on the loca-
tion of the fuel filter (stage 2) , refer to
the “Engine compartment check loca-
tions” in this section.

REMOVAL
WARNING
● Depending on the circumstance, fuel is
flammable. When inspecting or per-
forming service or repairs on the fuel
system, to reduce the possibility of fire
and resulting severe personal injury,
death, or property damage, never
smoke or allow sparks or flames (such
as pilot lights, electrical switches, or
welding equipment) in the work area.
● Do not bleed the fuel system of a hot
engine; this can result in fuel spilling
onto a hot exhaust manifold, which can
cause a fire.
1. Push the ignition switch to the OFF position and wait 2 minutes before disconnecting the
battery.
2. Disconnect the batteries.
3. Clean the area around the stage 2 fuel filter. 4. Remove the cover
Afrom the stage 2 fuel
filter.
NOTE:
Remove the cover slowly to avoid fuel spill-
age. 5. Remove the fuel filter element
Cfrom the
cover by hand.
6. Remove and discard the sealing o-ring
B
from the cover.
INSPECTION
Inspect the fuel filter housing and cover for
cracks, passage blockages, and other damage. If
damage is found, replacement is mandatory.
It is recommended that you visit a NISSAN dealer
for this service.
