cooling NISSAN XTERRA 2015 N50 / 2.G User Guide

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. Refer
to the “Appearance and care” section of this
manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir. When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions 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. Move the shift lever to P
(Park) .
● Be sure the ignition switch is in the OFF
or LOCK 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 jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
● 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, support
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 by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.

7. Air cleaner
8. Drive belt location
9. Radiator cap
10. Power steering fluid reservoir
11. Battery
12. Engine coolant reservoirThe 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 anti-freeze 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. Refer to precautions in “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.

Maintenance and do-it-yourself8-7

●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. Refer to the NISSAN Service and
Maintenance Guide for more details.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level, add coolant to the MAX level. 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.
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.
The engine coolant reservoir is a pressur-
ized tank. When installing the cap, tighten.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
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 cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.

The current sensorAis 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.
1. Power steering fluid pump pulley
2. Automatic belt tensioner pulley
3. Cooling fan pulley
4. Air conditioner compressor pulley

WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly. 1. Visually inspect the belt for signs of unusual
wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it replaced
or adjusted by a NISSAN dealer.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule found in the
“NISSAN Service and Maintenance Guide”.
