2017 NISSAN TITAN Owners Manual

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.”
CHECKING ENGINE OIL LEVEL
NOTE:
The factory fill oil may include a red dye
that is added for manufacturing quality pro-
cesses. The dye makes the oil appear to be
red. This is normal. The red dye will be
flushed from the engine after approxi-
mately 4–5 oil changes.1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature. 3. Turn off the engine.
Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way.

5. Remove the dipstick again and check the oillevel. It should be between the high and low
marks
B. This is the normal operating oil
level range. If the oil level is below the low
mark
A, remove the oil filler cap and pour
recommended oil through the opening. Do
not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
CAUTION
Oil level should be checked regularly. Op-
erating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.

2. Start the engine and let it idle until it reaches operating temperature, then turn it off.
3. Remove the oil filler cap
Aby turning it
counterclockwise.
4. Place a large drain pan under the drain plug
B.
5. Remove the drain plug
Bwith a wrench by
turning it counterclockwise and completely
drain the oil.
Remove and replace the engine oil filter at
this time. For additional information, refer to
“Changing engine oil filter” in this section.
● Waste oil must be disposed of prop-
erly.
● Check your local regulations.
WARNING
●Prolonged and repeated contact with
used engine oil may cause skin cancer.
● Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep used engine oil out of reach of
children.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
6. Clean and reinstall the drain plug. Securely tighten the drain plug with a wrench. Do not
use excessive force.
Drain plug tightening torque: 25 ft-lb (34 N·m)
7. Refill engine with recommended oil through the oil filler opening, then install the oil filler
cap securely.
For additional information on drain and refill
capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual. The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.

CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and applythe parking brake.
2. Turn the engine off.
3. Remove bolts
Aand skid plate. 4. Place a large drain pan under the oil filter
B.
5. Loosen the oil filter with an oil filter wrench by turning it counterclockwise. Then remove
the oil filter by turning it by hand.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
6. Wipe the engine oil filter sealing surface with a clean rag.

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.

INSPECTION
Inspect the fuel filter housing and module 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.
INSTALLATION
CAUTION
Do not pre-fill the fuel filter with fuel.
Pre-filling the filter can result in debris
entering the fuel system and damaging
fuel system components.
10. Lubricate the inner seal of the fuel filter ele- ment with petroleum jelly or white lithium
grease.
11. Install a new o-ring on the housing. Lubricate the o-ring with petroleum jelly or white
lithium grease. NOTE:

that has not had fuel in it, lubricate the lip
seal at the bottom of the fuel filter element
with petroleum jelly or white lithium grease
before placing it into the housing.
12. Install the fuel filter element into the fuel filter
housing and make sure the four tabs
Fare
properly seated into the four slots
