2019 NISSAN FRONTIER engine

Four-Wheel Drive (4WD) models
with manual transmission
NISSAN recommends that towing dollies
be used when towing your vehicle or place
the vehicle on a flatbed truck as illustrated.
If you must use a pull behind tow truck put
the manual transmission in N (Neutral).
For 4WD vehicles, always tow with the
transfer case in the 2 HI position.
Your vehicle speed should never exceed
60 mph (97 km/h) when towing your ve-
hicle. Af ter towing 500 miles, start and idle
the engine with the transmission in N (Neu-tral) for two minutes. Failure to idle the en-
gine af ter every 500 miles of towing may
cause damage to the transmission’s inter-
nal parts.
CAUTION
Failure to follow these guidelines can
result in severe transmission damage.
∙ If you have to tow manual transmis-
sion models with the rear wheels on
the ground (if you do not use towing
dollies) or four wheels on the ground:
– Always release the parking brake. – Move the transmission shif t lever
to the N (Neutral) position
– For 4WD vehicles, always tow with the transfer case in the 2 HI
position.
– Observe the following restricted towing speeds and distances for
manual transmission models only:
Speed: Below 60 mph (97 km/h)
Distance: Less than 500 miles
(805 km)
When towing long distances or speeds in
excess of 60 mph (97 km/h), remove the
propeller shaf t before towing to prevent
damage to the transmission. It is recom-
mended that you visit a NISSAN dealer for
more information.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions 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. For manual transmission
models, move the shif t lever to N (Neu-
tral). For Automatic Transmission (A/T)
move the shif t lever to P (Park)
∙ Be sure the ignition key is in the OFF orLOCK 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ 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, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off.
It is recommended that you visit a
NISSAN dealer for this service.
CAUTION
∙ Do not work under the hood while theengine 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 the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer 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. 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 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 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 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) (or
equivalent coolant), including Genu-
ine 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.
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 will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
If the cooling system frequently requires
coolant, it is recommended 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.
