engine coolant NISSAN TITAN 2019 Owner´s Manual

will be reduced. It is recommended that
you visit a NISSAN dealer or qualified tech-
nician immediately. For additional informa-
tion, refer to “Diesel Particulate Filter (DPF)”
in the “Do-it-yourself ” section of this
manual.
Engine Warming Keep Foot on Brake
This message appears during cold start
conditions when:∙ Brake pedal is depressed
∙ Push-button start button has been pressed
∙ Coolant temperature is below thresh- old
Keep foot on the brake until the engine
starts, which can take up to approximately
4 seconds. For additional information, refer
to “Starting the diesel engine” in the “Start-
ing and stopping the engine” section of this
manual. Engine Shutdown: Stop Safely
This message appears 30 seconds before
the vehicle is shutdown due to an above
normal operating exhaust temperature.
The Malfunction Indicator Light (MIL) and
malfunction warning light (red) will illumi-
nate. It is recommended that you visit a
NISSAN dealer or other qualified technician
immediately.
Engine Power Reduced
This message appears when the engine is
not operating under normal conditions. For
additional information, refer to “Engine Pro-
tection Mode” in the “Introduction” section
of this manual.
Service Air Filter
This warning appears when the air filter
needs to be serviced. For additional infor-
mation, refer to “Air cleaner” in the ”Mainte-
nance” section of the Titan Diesel Owner’s
Manual.Engine Oil Service due XX
This message is a count down of mileage
until the next engine oil service is due. Mile-
age until next required engine oil service
will be displayed by the vehicle information
display and will decrease at a higher rate as
vehicle operation severity (high duty cycle)
increases.
Coolant Level Low: See Owner’s Manual
This warning appears when the coolant
level in the reservoir is below the MIN level.
For additional information, refer to “Engine
Cooling System” in this manual.
Low Fuel Pressure: See Owner’s Manual
This message appears when low fuel pres-
sure has been detected downstream of
the stage 2 fuel filter. This message can
indicate the fuel filters are restricted and
require replacement. It is recommended
that you have the system checked by a
NISSAN dealer or other qualified technician.

CAUTION
If the engine does not start, place the
ignition switch in the OFF position and
wait 10 seconds before cranking again,
otherwise the starter could be
damaged.3. Allow the engine to idle for at least 30 seconds af ter starting. Do not race
the engine while warming it up. Drive at
a moderate speed for a short distance
first, especially in cold weather.
In cold weather, keep the engine run-
ning for a minimum of 2–3 minutes
before shutting it off. Starting and
stopping the engine over a short pe-
riod of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Push the ignition switch to the OFF posi-
tion.
To prolong the engine life (especially af ter
extended high speed, high ambient tem-
perature, or during heavy load operation,
such as trailering), it is recommended that
a hot engine be idled for 3–5 minutes be-
fore shutting down. This allows the turbo-
charged engine to cool down.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating it under load.
∙ Do not operate the engine at idle for extended periods.
∙ Prevent engine lugging by selecting the appropriate transmission gear.
∙ Monitor the vehicle oil pressure and temperature gauges.
∙ Check fluid levels frequently (oil and coolant).
∙ Vary the throttle position at highway speeds when carrying weight or tow-
ing.
NOTE:
Extended light or no load operation will
extend the time before the engine
reaches its full efficiency. If the engine is
operated in this manner, reduced fuel
economy and power may be observed.
The aforementioned procedure should be
observed for the first 6,000 miles. The en-
gine run-in is improved by operating the
vehicle under load.
REMOTE ENGINE START (if so
equipped)
CAUTION
Laws in some jurisdictions prohibit use
of Remote Engine Start.
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps: 1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, refer to “NISSAN
Intelligent Key®” in the “Pre-driving checks
and adjustments” section of the Titan
Owner’s Manual.

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” in the “In case of
emergency ” section of the Titan Own-
er’s 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 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, 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 protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze 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 cause severe engine
damage. ∙ The life expectancy of the factory-fill
coolant is 45,000 miles (78,000 km) or
3 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 Titan Owner’s Manual.
∙ Use Nitrite Free Coolant or equivalent. The use of coolant containing Nitrites,
could cause severe engine damage.
ENGINE COOLING SYSTEM
Do-it-yourself7-3

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
45,000 miles (78,000 km) or 3 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 the Titan Own-
er’s Manual.
CAUTION
Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
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.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
