radiator NISSAN ARMADA 2021 Owner´s Manual

8-4Do-it-yourself
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 anti-freeze and coolant pro-
tection. The antifreeze solution contains
rust and corrosion inhibitors. Additional
engine cooling system additives are not
necessary.
WARNING
.Never remove the radiator or
coolant reservoir cap when the
engine is hot. Wait until the en-
gine and radiator cool down.
Serious burns could be caused
by high pressure fluid escaping
from the radiator. See precau-
tions in “If your vehicle overheats”
(P.6-14).
. The radiator is equipped with a
pressure type radiator cap. To
prevent engine 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 damage to
the engine, transmission and/or
cooling system.
. When adding or replacing cool-
ant, be sure to use only Genuine
NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent. Gen-
uine 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 Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain mini-
mum antifreeze 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 en-
gine cooling system.
. The life expectancy of the fac-
tory-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
Genuine NISSAN Long Life Anti-
freeze/Coolant (green), or the use
of non-distilled water will reduce
the life expectancy of the factory-
fill coolant. Refer to the “9. Main-
tenance and schedules” section
of this manual for more details.
ENGINE COOLING SYSTEM

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below MIN
, open the reservoir
tank cap and add coolant up to the MAX
level. If the reservoir tank 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
tank up to the MAX level
.
Tighten the cap securely after adding
engine coolant.
If the cooling system requires coolant
frequently, have it checked. It is recom- mended you visit a NISSAN dealer for
this service.
CHANGING ENGINE COOLANT
It is recommended that major cooling
system repairs be performed by a NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.
WARNING
.
To avoid the danger of being
scalded, never change the cool-
ant when the engine is hot.
. Never remove the radiator cap or
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 pos-
sible.
. Keep coolant out of reach of
children and pets. Engine coolant must be disposed of
properly. Check your local regulations.

9-4Maintenance and schedules
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Steering wheel:Check for changes in the
steering conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are
operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate
properly and that the wipers do not
streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example,
each time you check the engine oil or
refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1.
Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in- spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5-
4) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control
dust. It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt
may accumulate. For additional informa-
