1998 NISSAN PATHFINDER fuel filter

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.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 P
(Park).
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
and fan belts.
IIt is advisable to remove necktie 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.
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.
IThe 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.
IDo not work under the engine hood
while it is hot. Always turn off the
engine and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized com-ponent connector while the ignition
key is on.
IAvoid direct contact with used engine
oil. Improperly disposed motor oil and/
or other vehicle fluids can hurt the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This ª8. Do-it-yourselfº section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt about
any servicing, have it done by your NISSAN
dealer.

CHANGING ENGINE OIL1. Park the vehicle on a level surface and
apply the parking brake.
2. Warm up the engine until it reaches oper-
ating temperature, and then turn it off.
3. Place a large drain pan under the drain
plug.
4. Remove the oil filler cap.
5. Remove the drain plug with a wrench and
completely drain the oil.
If the oil filter is to be changed, remove and
replace it at this time. See later in thissection for changing engine oil filter.
Be careful not to burn yourself, as the
engine oil is hot.Waste oil must be disposed of properly.
Check your local regulations.
6. Clean and re-install the drain plug and new
washer. Securely tighten the drain plug with
a wrench. Do not use excessive force.
Drain plug tightening torque:
22 to 29 ft-lb (29 to 39 N×m)
7. Refill engine with recommended oil and
install the oil filler cap securely.
See ªCapacities and recommended
fuel/lubricantsº in the ª10. Technical and
consumer informationº section for refill ca-
pacity.
8. Start the engine.
Check for leakage around the drain plug.
Correct as required.
9. Turn the engine off and wait several min-
utes. Check the oil level with the dipstick.
Add engine oil if necessary.
IProlonged and repeated contact with
used engine oil may cause skin can-
cer.
ITry to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
IKeep used engine oil out of reach of
children.

3. Check each new spark plug gap with a
feeler gauge. Correct it as required.
4. Install spark plugs.
When installing a plug, turn it in two or
three turns by hand and then tighten with a
spark plug wrench. Be careful not to over-
tighten it.
Tightening torque:
14 to 22 ft-lb (20 to 29 N×m)
5. Reconnect the spark plug cables to their
original positions.The filter element should not be cleaned and
reused as it is given a special treatment. We
recommended it be replaced according to the
maintenance intervals. See ªPeriodic mainte-
nanceº in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
IOperating the engine with the air
cleaner off can cause you or others to
be burned. The air cleaner not onlycleans the air, it stops flame if the
engine backfires. If it is not there, and
the engine backfires, you could be
burned. Do not drive with it off, and
be careful working on the engine with
the air cleaner off.
INever pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life
and performance. Nissan recommends the
use of a low friction oil (energy conserving oil)
in order to improve fuel economy and con-
serve energy. Oils which do not have the
specified quality label should not be used as
they could cause engine damage.Only those engine oils with the American Pe-
troleum Institute (API) CERTIFICATION
MARK on the front of the container should be
used. This type of oil supersedes the existing
API SG or SH and Energy Conserving II
categories.
If you cannot find engine oil with the CERTI-
FICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation SG or SH, or in combination with
other categories (for example, SG/CC or
SG/CD) may also be used if one with the API
CERTIFICATION MARK cannot be found.Mineral based or synthetic type oils may be
used in your NISSAN vehicle. These oils must
however, meet the API quality and SAE vis-
cosity ratings specified for your vehicle. Do not
mix mineral based and synthetic type oils in
the engine at the same time.
Oil additivesNISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.Oil viscosityThe engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the ve-
hicle will be operated before the next oil
change. The chart recommended SAE viscos-
ity number shows the recommended oil vis-
cosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.
