1998 NISSAN PATHFINDER Owners Manual

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.

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.When adding or replacing the coolant,
be sure to use an ethylene glycol anti-
freeze with the proper mixture ratio of
50% anti-freeze and 50% distilled water.
The use of other types of coolant solu-
tions may damage your engine cooling
system.Outside temperature

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. Serious burns could be caused
by high pressure fluid escaping from
the radiator. See ªIf your vehicle over-
heatsº in the ª6. In case of emer-
gencyº section.
IThe radiator is equipped with a pres-
sure cap. Use only a genuine cap as a
replacement.
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.

performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.
IImproper servicing can result in reduced
heater performance and engine overheat-
ing.
ITo avoid the danger of being scalded,
never change the coolant when the
engine is hot.

1. Perform the following procedure to open
the heater water cock.
ITurn the ignition key from OFF to ON.
IMove the heater or air conditioner tem-
perature control dial to the maximum hot
position then turn the ignition key to
OFF.
2. Open the radiator drain plug and radiator
cap.
Open the drain plugs on the engine block.3. Open the air release plug to drain the
coolant.
4. Flush the cooling system by running fresh
water through the radiator.
5. Close the radiator drain plug and engine
block drain plugs securely.
6. See the ªTechnical informationº section for
cooling system capacity.
Fill the radiator slowly with the proper mix-
ture 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.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
opening. 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.
Reinsert 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.
Oil level should be checked regularly.
Operating with insufficient amount of oil
can damage the engine, and such dam-
age 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 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.

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.
(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.
IAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
