check engine NISSAN PATHFINDER 2002 R50 / 2.G Owner's Manual

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
IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
IDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to the neutral position (automatic
transmission to P (Park)).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-tioner temperature control to maximum hot
and fan control to high speed.
3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. 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 cooling fan belt is missing or loose or
the cooling fan does not run, stop the
engine.
WARNING
IBe careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in, the
cooling fan, or drive belt.
IThe engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest NISSAN dealer.

Your new NISSAN has been designed to have
minimum maintenance requirements with
longer service intervals to save you both time
and money. However, some day-to-day and
regular maintenance is essential to maintain
your NISSAN's good mechanical condition, as
well as its emission and engine performance.
It is the owner's responsibility to make sure
that scheduled maintenance, as well as gen-
eral maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives the
proper maintenance care. You are a vital link
in the maintenance chain.
Scheduled maintenance:
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your ªService and Main-
tenance Guideº. You must refer to that guide to
ensure that necessary maintenance is per-
formed on your NISSAN at regular intervals.
General maintenance:
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these procedures regularly as prescribed.Performing general maintenance checks re-
quire minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
your NISSAN dealer.
Where to go for service:
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and tuned by an authorized
NISSAN dealer.
NISSAN technicians are well-trained special-
ists and are kept up to date with the latest
service information through technical bulletins,
service tips, and in-dealership training pro-
grams. They are completely qualified to work
on NISSAN vehiclesbeforethey work on your
vehicle, rather than after they have worked on
it.
You can be confident that your NISSAN deal-
er's service department performs the best job
to meet the maintenance requirements of your
vehicle Ð in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer check it promptly. In
addition, you should notify your NISSAN
dealer if you think that repairs are required.
When performing any checks or maintenance
work, closely observe the ªMaintenance pre-
cautionsº later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMSAdditional information on the following
items with ª*º is found later in this section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*:
Check the pressure with a gauge at least once
a month and always prior to long distance
trips, including the spare, and adjust to the
specified pressure if necessary. Check care-
fully for damage, cuts or excessive wear.

Wheel nuts*:
When checking the tires, make sure no nuts
are missing, and check for any loose nuts.
Tighten if necessary.
Tire rotation*:
Tires should be rotated every 7,500 miles
(12,000 km). However, the timing for tire rota-
tion may vary according to your driving habits
and road surface conditions.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº in the
Warranty Information Booklet (US) or ªTire
Safety Informationº in the Warranty Informa-
tion booklet (Canada).
Windshield:Clean the windshield on a regu-
lar basis. Check the windshield at least every
six months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.Windshield wiper blades*:
Check for cracks or wear if they do not wipe
properly.
Doors and engine hood:
Check that all doors and the engine hood,
operate properly. Also ensure that all latches
lock securely. Lubricate hinges, latches, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Inside the vehicleLights*:
Clean the headlights on a regular basis. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all oper-
ating properly and installed securely. Also
check headlight aim.INTERIOR MAINTENANCEThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.Warning lights and chimes:
Make sure that all warning lights and chimes
are operating properly.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in sufficient quantity when
operating the heater or air conditioner.
Steering wheel:
Check for changes in the steering conditions,
such as excessive freeplay, hard steering or
strange noises.
Seats:
Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and
that the locks (if so equipped) hold securely in
all latched positions.

On a fairly steep hill check that your vehicle is
held securely with the selector lever in the P
position without applying any brakes.
Under the hood and vehicleThe maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.
Engine oil level*:
Check the level after parking the vehicle on a
level spot and turning off the engine. (Be sure
to wait a few minutes to allow the oil to drain
back into the sump.)
Brake and clutch fluid levels*:
Make sure that the brake and clutch fluid level
is between the MAX and MIN lines on the
reservoir.
Power steering fluid level* and lines:
Check the level when the fluid is cold and the
engine is turned off. Check the lines for proper

See ªPrecautions when starting and drivingº in
the ª5. Starting and drivingº section for exhaust
gas (carbon monoxide).
Underbody:
The underbody is frequently exposed to corro-
sive 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 accumu-
late. For additional information, see ªCleaning
exteriorº in the ª7. Appearance and careº sec-
tion.
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 cor-
rected immediately.When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNING
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.
IBe sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.
IIt is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IYour vehicle is equipped with an au-
tomatic 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 run-
ning. To avoid injury, always discon-
nect the negative battery cable before
working near the fan.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
CAUTION
When adding or replacing the coolant,
be sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized water/
distilled water. The use of other types of
coolant solutions may damage your en-
gine cooling system.Outside tempera-

WARNING
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator. Wait
until the engine and radiator cool
down. See ªIf your vehicle overheatsº
in the ª6. In case of emergencyº sec-
tion.
IThe radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level, add coolant to the MAX
level. If the reservoir tank is empty, check the
coolant level in the radiatorwhen 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.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.
5. Remove the dipstick again and check the
oil level. It should be between the H and Lmarks.If the oil level is below the L mark,
remove the oil filler cap and pour recom-
mended oil through the opening. Do not
overfill.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
changes or during the break-in period, de-
pending on the severity of operating con-
ditions.
