2017 NISSAN SENTRA engine overheat

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 NISSAN Service and Maintenance
Guide.

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 the NISSAN
Service and Maintenance Guide.
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.
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.

Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents or
similar ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, it is recommended that you have a
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of the
vehicle, for which NISSAN is not respon-
sible.Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit a NISSAN dealer for
servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
