CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water may reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to “Maintenance
and schedules” section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service. For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
∙ Never remove the radiator or engine coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.VK56VD engine (non-XD model)

Engine coolant must be disposed of prop-
erly. Check your local regulations.
For additional information on changing the
Cummins 5.0L engine coolant, refer to the
Titan Diesel Owner’s Manual.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
15 minutes for the oil to drain back
into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the H
(High) and L (Low) marksB. This is the
normal operating oil level range. If the
oil level is below the L (Low) mark
A,
remove the oil filler cap and pour rec-
ommended 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 sever-
ity of operating conditions.

sive force.
Drain plug tightening torque: 25 f t-lb (34 N·m) 8. Refill engine with recommended oil
through the oil filler opening, then in-
stall the oil filler cap securely.
For additional information on drain
and refill capacity, refer to “Recom-
mended fluids/lubricants and capaci-
ties” in the “Technical and consumer
information” section 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 deter-
mine when the proper amount of oil is
in the engine.
9. Start the engine. Check for leakage around the drain plug and oil filter. Cor-
rect as required.

WARNING
Be sure the ignition switch is in the OFF
or LOCK position before servicing drive
belt. The engine could rotate
unexpectedly.1. Visually inspect the belt for signs of un-
usual wear, cuts, fraying or looseness. If
the belt is in poor condition or is loose,
have it replaced or adjusted. It is recom-
mended that you visit a NISSAN dealer
for this service.
2. Have the belt checked regularly for condition and tension in accordance
with the maintenance schedule. For
additional information, refer to the
"Maintenance and schedules" section
of this manual.

REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped spark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the “Maintenance and sched-
ules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
∙ Always replace spark plugs with rec-
ommended or equivalent ones.
