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.
WARNING
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
N (Neutral). For an automatic trans-
mission, move the shift lever to P
(Park).
IBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
IIt is advisable to remove ties 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
necessary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, the fuel filter or fuel lines
should be serviced by an authorized
NISSAN dealer because the fuel
lines are under high pressure even
when the engine is off.
CAUTION
IDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
IAvoid contact with used motor oil.
Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local regulations for disposal of ve-
hicle fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round,
genuine NISSAN anti-freeze coolant solu-
tion. The anti-freeze solution contains rust
and corrosion inhibitors, therefore additional
engine cooling system additives are not
necessary.
CAUTION
When adding or replacing coolant, be
sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized water or
distilled water. The use of other types
of coolant solutions may damage the
engine cooling system.

WARNING
INever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radiator.
See precautions in ``If your vehicle
overheats'' found in the ``In case of
emergency'' section of this manual.
IThe radiator is equipped with a pres-
sure cap. Use only a genuine NIS-
SAN cap as it's replacement.
CHECKING ENGINE COOLANT
LEVEL
Check 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.

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.CHANGING ENGINE COOLANT
IMajor cooling system repairs should be
performed by an authorized NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Ser-
vice Manual.
IImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
ITo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
1. Open the radiator drain valve. Open the
drain plugs on the engine block.
2.
Open the radiator cap to drain the coolant.
3. Flush the cooling system by running
fresh water through the radiator.
4. Close the radiator drain valve and drain
plug on the engine block securely.5. See ``Capacities and recommended
fuel/lubricants'' in the ``Technical and
consumer information'' section for cool-
ing system capacity. Fill the radiator
slowly with the proper mixture of coolant
and water. Fill the reservoir tank slowly
up to the MAX level.

8. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine two or three times
under no load. Watch the engine coolant
temperature gauge for signs of overheat-
ing.9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up the
MAX level.10. Open and close the air release plug to
release air. Then fill the radiator again
