2016 NISSAN TITAN cooling

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, use only a Genuine
NISSAN radiator 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, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. 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 will reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer to
the ‘Maintenance’ section of this
manual.
For additional information on the Cummins 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 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 will re-
duce the life expectancy of the factory-fill coolant.
For additional information, refer to “Maintenance”
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.
For additional information on checking the Cum-
mins 5.0L engine coolant level, refer to the “Titan
Diesel Owner’s Manual”.
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
thoroughly with soap or hand cleaner as
soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
For additional information on changing the Cum-
mins 5.0L engine coolant, refer to the “Titan
Diesel Owner’s Manual”.

CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery. Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator.
The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.

WARNING
Be sure the ignition switch is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.

UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. For
additional information, refer to the “Appearance
and care” section of this manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir. The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
Items marked with
“*”are recommended by
NISSAN for reliable vehicle operation. You are
not required to perform maintenance on these
items in order to maintain the warranties which
come with your NISSAN. Other maintenance
items and intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section of this
manual.
NOTE: NISSAN does not advocate the use of
non-OEM approved aftermarket flushing sys-tems and strongly advises against performingthese services on a NISSAN product. Many of theaftermarket flushing systems use non-OEM ap-proved chemicals or solvents, the use of whichhas not been validated by NISSAN.
For recommended fuel, lubricants, fluids, grease,
and refrigerant, refer to “Recommended
fluids/lubricants and capacities” in the “Technical
and consumer information section of this
manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive Belts*
Check engine drive belts for wear, fraying or
cracking and for proper tension. Replace any
damaged drive belts.
Engine Air Filter
Replace at specified intervals. When driving for
prolonged periods in dusty conditions,
check/replace the filter more frequently.
Engine Coolant*
Replace coolant at the specified interval. When
adding or replacing coolant, be sure to use only
Genuine NISSAN Long Life Antifreeze/Coolant
(blue) or equivalent with the proper mixture. (For
additional information on the proper mixture for
your area, refer to Engine cooling system” in the
“Do-it-yourself” section of this manual or the “Ti-
tan Diesel Owner’s Manual”.)
NOTE: Mixing any other type of coolant or the use
of non-distilled water may reduce the recom-
mended service interval of the coolant.
