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.

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.

CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the en-
gine, and such damage is not covered
by warranty.
For additional information on checking the
Cummins 5.0L engine oil level, refer to the
Titan Diesel Owner’s Manual.
CHANGING ENGINE OIL

Aby turning it
counterclockwise.
5. Place a large drain pan under the drain plug
B.
6. Remove the drain plug
Bwith a
wrench by turning it counterclockwise
and completely drain the oil.
If the oil filter is to be changed, remove
and replace it at this time. For addi-
tional information, refer to “Changing

WARNING
∙ Prolonged and repeated contact withused 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 en-
gine oil may be hot.
7. Clean and reinstall the drain plug and a new washer. Securely tighten the drain
plug with a wrench. Do not use exces-
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.
10. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
For additional information on changing the
Cummins 5.0L engine oil, refer to the Titan
Diesel Owner’s Manual.
