When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift lever to P
(Park)
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
The automatic engine cooling fan (if so
equipped) may come on at any time
without warning, even if the ignition
switch is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
● If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
CAUTION
● Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ●
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
This “Do-it-yourself” section gives instructions
regarding only those items which are relatively
easy for an owner to perform.
A Genuine NISSAN service manual is also avail-
able. For additional information, refer to “Owner’s
Manual/Service Manual order information” in the
“Technical and consumer information” section of
this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing, it
is recommended that you have it done by a
NISSAN dealer.

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round antifreeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
WARNING
●Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. For additional information
on precautions, refer to “If your vehicle
overheats” found in the “In case of
emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, it is recommended that
you use only a Genuine NISSAN radia-
tor cap.
CAUTION
● Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
● When adding or replacing coolant, it is
recommended that you use only Genu-
ine NISSAN Long Life
Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . If additional freeze protection
is needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling
system. ●
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water may reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer to
the Maintenance and schedules sec-
tion of this manual.
For additional information on the Cummins 5.0L
engine cooling system, refer to the “Titan Diesel
Owner’s Manual”.
ENGINE COOLING SYSTEM
Do-it-yourself8-5

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 insufficient 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 expectancy 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 expectancy of the factory-fill cool-
ant. For additional information, refer to “Mainte-
nance 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 “Engine com-
partment 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 overheat-
ing.
WARNING
●
To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator or engine
coolant reservoir cap when the engine
is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and applythe 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. Re- insert 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 oper-
ating oil level range. If the oil level is below
the L (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.
