2004 NISSAN PATHFINDER engine oil

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

Do not work under the engine hood
while it is hot. Turn off the engine and
wait until it cools down.

Never connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.

Never leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.

Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant, and/or
other vehicle fluids can hurt the envi-ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This section gives instructions regarding only
those items which are relatively easy for an
owner to perform. More involved service should
be done by your NISSAN dealer.
A genuine NISSAN Service Manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “9. Technical and con-
sumer information” section.
You should be aware that incomplete or im-
proper servicing may result in operating difficul-
ties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, have it done by your NISSAN
dealer.8-6

3. Open the air release plug(s) to drain the
coolant.
4. Flush the cooling system by running fresh
water through the radiator.

Waste coolant must be disposed of
properly.

Check your local regulations.
5. Close the radiator drain plugs and engine
block drain plugs securely.
6. See the “9. Technical and consumer informa-
tion” section for cooling system capacity.
Fill the radiator slowly with the proper mixture
of coolant and water. Fill the reservoir tank
slowly up to the MAX level. Then install the
radiator cap and close the air release plug(s).
7. Start the engine and warm it up until it
reaches normal operating temperature. Then
race the engine 2 or 3 times under no load.
Watch the coolant temperature gauge for
signs of overheating.
8. Stop the engine. After it completely cools
down, refill the radiator up to the filler open-
ing. Fill the reservoir tank up the MAX level.
9. Check the radiator drain plug and engine
block drain plugs for any sign of leakage.
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. Rein-
sert it all the way.
5. Remove the dipstick again and check the oil
level. It should be between the H and L
marks. 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.
CAUTION
Oil level should be checked regularly.

Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered by warranty.
CHANGING ENGINE OIL1. Park the vehicle on a level surface and apply
the parking brake.
2. Warm up the engine until it reaches operat-
ing temperature, and then turn it off and wait
more than 10 minutes.
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 this sectionfor changing engine oil filter.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.

Waste oil must be disposed of prop-
erly.

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 through
the oil filler opening, then install the oil filler
cap securely.
See “Capacities and recommended
fuel/lubricants” in the “9. Technical and con-
sumer information” section for drain and refill
capacity.
The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper

amount of oil is in the engine.
8. Start the engine.
Check for leakage around the drain plug.
Correct as required.
9. Turn the engine off and wait more than 10
minutes. Check the oil level with the dipstick.
Add engine oil if necessary.
WARNING

Prolonged and repeated contact with
used engine oil may cause skin can-
cer.

Try to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.

Keep used engine oil out of reach of
children.
CHANGING ENGINE OIL FILTER1. 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.
(Depending on the engine model, a special
cap-type wrench may be required. See your
NISSAN dealer.) Then remove the oil filter by
turning it by hand.
CAUTION
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.
Oil filter tightening torque:
10.85 to 15.12 ft-lb
(14.7 to 20.5 N⋅m)
7. Start the engine and check for leakage
around the oil filter. Correct as required.
8. Turn the engine off and wait several minutes.
Check the oil level. Add engine oil if neces-
sary.

under severe conditions require frequent
checks of the battery fluid level.
WARNING
Be sure the ignition key is in the OFF or
LOCK position. The engine could rotate
unexpectedly.
1. Visually inspect each belt for signs of unusual
wear, cuts, fraying oil adhesion or looseness.
If the belt is in poor condition or loose, have
it replaced or adjusted by your NISSAN
dealer.
2. Have the belts checked regularly for condi-tion and tension.

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 conserve 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 Petro-
leum Institute (API) CERTIFICATION MARK onthe front of the container should be used. This
type of oil supersedes the existing API SG, SH,
or SJ and Energy ConservingI&IIcategories.
If you cannot find engine oil with the API CER-
TIFICATION MARK, use an API grade SG/SH,
Energy ConservingI&IIorAPIgrade SJ, Energy
Conserving oil. An oil with a single designation
SG or SH, or in combination with other catego-
ries (for example, SG/CC or SG/CD) may also
be used if one with the API CERTIFICATION
MARK cannot be found. An ILSAC grade GF-I &
GF-II oil can also be used.
NISSAN does not recommend synthetic type
oils but recommends mineral based oils. Theseoils must however, meet the API quality and SAE
viscosity ratings specified for your vehicle.
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 important
that the engine oil viscosity be selected based
on the temperatures at which the vehicle will be
operated before the next oil change. The chart
recommended SAE viscosity number shows the
recommended oil viscosities for the expected
ambient temperatures. Choosing an oil viscosity
other than that recommended could cause seri-
ous engine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-quality
genuine Nissan oil filter. When replacing, use the
genuine oil filter or its equivalent for the reason
described in change intervals.
