1997 NISSAN PATHFINDER engine

IAutomatic transmission models can-
not be started by pushing. This may
cause transmission damage.
IThree-way catalyst equipped models
should not be started by pushing
since the three-way catalyst may be
damaged.
INever try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.
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:
IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo avoid the danger of being burned,
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 ªPº).
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 ªmaximumhotº and fan control to ªhigh speedº.
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.
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.

Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, the running fan
or belts.
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.When towing your vehicle, all State (Provincial
in Canada) and local regulations for towing
must be followed. Incorrect towing equipment
could damage your vehicle. Towing instruc-
tions are available from your NISSAN dealer.
Local service operators will generally be famil-
iar with the applicable laws and procedures for
towing. To assure proper towing and to pre-
vent accidental damage to your vehicle,
NISSAN recommends that you have a service
operator tow your vehicle. It is advisable to
have the service operator carefully read the
following precautions.
INever ride in a vehicle that is being
towed.
INever get under your vehicle after it
has been lifted by a tow truck.
IWhen towing, make sure that the
transmission, axles, steering system
and power train are in good order. If
any unit is damaged, a dolly must be
used.IWhen towing with the front wheels on
the ground:
Turn the ignition key to the ªOFFº
position and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
place the ignition key in the ªLOCKº
position. This will result in damage to
the steering lock mechanism.
IWhen towing manual transmission
models with the rear wheels on the
ground, release the parking brake
and move the gearshift lever to the
neutral position.
IFor 4-wheel drive model:
Move the transfer case shift lever into
the ª2Hº position and the transmis-
sion shift lever into the neutral (ªNº)
position.
IAttach safety chains for all towing.

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 ªPº
(Park).
IBe sure the ignition key is in the
ªOFFº or ªLOCKº position when per-
forming 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.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 engineoil. 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 ªDo-it-yourself operationsº section gives
instructions 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.

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 precautions in ªIf
your vehicle overheatsº found in the
ªIn case of emergencyº section.
IThe radiator is equipped with a pres-
sure cap. Use a NISSAN genuine cap
or its equivalent when replacement is
required.
CHECKING COOLANT LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the ªMINº level, add coolant to the
ªMAXº 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 ªMAXº level.
