1997 NISSAN PATHFINDER engine oil

CHANGING OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Loosen the oil filter with an oil filter wrench.
(A specialcap-typewrench will assist with
oil filter removal on models with the V6
engine. This tool can be purchased from
your NISSAN dealer.) Then remove the oil
filter by turning it by hand.
Be careful not to burn yourself, as the
engine oil may be hot.
4. Wipe the engine oil filter mounting surface
with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine.
5. Coat the rubber gasket on the new filter
with engine oil.
6. Screw in the oil filter until a slight resistance
is felt, then tighten an additional 2/3 turn.
7. Start the engine and check for leakage
around the oil filter. Correct as required.
8. Turn the engine off and wait several min-
utes. Check the oil level. Add engine oil if
necessary.
IWhen engine is running, keep hands,
jewelry, and clothing away from any
moving parts such as fan and drive
belt.

UNDER THE HOOD AND VEHICLE
The 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 coolant level*Check the coolant level
when the engine is cold.
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.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
ªMAXº and ªMINº lines on the reservoir.
Battery*Check the fluid level in each cell. It
should be between the ªMAXº and ªMINº lines.
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. (Be sure to wait a few minutes to allowthe oil to drain back into the sump.)
Power steering fluid level* and linesCheck
the level when the fluid is cold and the engine
is turned off. Check the lines for proper attach-
ment, leaks, cracks, etc.
Automatic transmission fluid level*Check
the level after putting the selector lever in ªPº
with the engine idling.
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 locate the
trouble and correct it. (See the carbon monox-
ide warning in the ªStarting and drivingº sec-
tion)
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, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. See the ªAppearance and Interior
Careº section for additional information.
Fluid leaksCheck under the vehicle for fuel,
oil, water or other fluid leaks after the vehiclehas 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 immediately.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It 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) CERTIFICATIONMARK 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 ªSGº or ªSHº, or in combination
with other categories (for example, ªSG/CCº or
ªSG/CDº) 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 musthowever, 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 additives
NISSAN 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 viscosity
The 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 ªRecommended SAE vis-
cosity numberº shows the recommended oil
viscosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.STI0077

Z01.2.1/R50-DX

Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine Nissan oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in ªchange intervalsº.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce engine life. Damage to engines caused
by improper maintenance or use of incorrect
oil and filter quality and/or viscosity is not
covered by the new Nissan vehicle warranties.
Your engine was filled with a high quality
engine oil when it was built. You do not have to
change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Op-
eration under the following conditions may
require more frequent oil and filter changes.
Ð repeated short distance driving at cold out-
side temperatures,
Ð driving in dusty conditions,
Ð extensive idling,Ð towing a trailer.
