2006 NISSAN SENTRA coolant level

If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc. take the following steps.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
cDo not open the hood if steam is com-
ing out.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time when the coolant
temperature is high.6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at a NISSAN
dealer.

Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
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) .
Automatic transmission fluid level*Check
the level after putting the selector lever in P with
the engine idling at operating temperature.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.
Engine coolant level*Check the coolant level
when the engine is cold.
Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake 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, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck 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 imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hosesCheck 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.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. See
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
cPark 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 shift lever to N (Neu-
tral) . For automatic transmission mod-
els, move the selector lever to P (Park) .
cBe sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
cNever leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.c
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
cIf 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.
cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.
cIf 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.
cNever 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.
cKeep smoking materials, flame and
sparks away from the fuel tank and
battery.cOn gasoline engine models with the
multiport fuel injection (MFI) system,
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.CAUTION
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cAvoid 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.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
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,
have it done by a NISSAN dealer.
