Do not attempt to start the engine by
pushing.
CAUTION
∙ Automatic transmission models can-not be push-started or tow-started.
Attempting to do so may cause trans-
mission damage.
∙ Three way catalyst equipped models should not be started by pushing
since the three way catalyst may be
damaged.
∙ Never try to start the vehicle by tow- ing it; when the engine starts, the for-
ward surge could cause the vehicle to
collide with the tow vehicle.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant res-
ervoir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc. take the
following steps: 1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maxi-
mum hot and fan control to high
speed. 3. If engine overheating is caused by
climbing a long hill on a hot day, run the
engine at a fast idle (approximately
1,500 rpm) until the temperature gauge
indication returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. If
steam or coolant is escaping, turn off
the engine. Do not open the hood fur-
ther until no steam or coolant can be
seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.

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. Addi-
tional engine cooling system additives are
not necessary.
WARNING
∙ Never remove the radiator or coolantreservoir 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 informa-
tion 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 addi-tives such as radiator sealer. Additives
may clog the cooling system and
cause damage to the engine, trans-
mission 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 manufactur-
er’s instructions to maintain minimum
antifreeze protection to -34° F (-37° C).
The use of other types of coolant solu-
tions 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
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue),
including 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"
section of this manual.
For additional information on the Cum-
mins 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 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)
