Temperature
A temperature increase accelerates the rate
of corrosion to those parts which are not
well ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use accelerates the corrosion process.
Road salt also accelerates the disintegra-
tion of paint surfaces.
To protect your vehicle from
corrosion:
cwash and wax your vehicle often to keep
the vehicle clean.
calways check for minor damage to the
paint and repair it as soon as possible.
ckeep drain holes at the bottom of the
doors open to avoid water accumulation.
ccheck the underbody for accumulation of
sand, dirt or salt. If present, wash with
water as soon as possible.
CAUTION
cNEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
cNever allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.

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
cPark 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 shift lever to P (Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cYour vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.c
If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.
before working on your vehicle.
cAlways wear eye protection when-
ever you work on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever 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.
c
Keep smoking materials, flame and
sparks away from fuel and the battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, 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
cDo not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.
cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is ON.
cNever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition is on.
c
Avoid contact with used engine oil.
Improperly disposed motor oil and/or
other vehicle fluids can hurt the en-
vironment. Always conform to local
regulations for disposal of vehicle
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, anti-
freeze coolant solution. The anti-freeze so-
lution 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 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 the engine cooling
system.

WARNING
cNever 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 radia-
tor. See precautions in ``If your ve-
hicle overheats,'' found in the ``In
case of emergency'' section.
c
The radiator is equipped with a pres-
sure cap. Use only a genuine NISSAN
cap.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir is empty, check the
coolant level in the radiatorwhen the en-
gine 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 up to the MAX level.

ENGINE COOLING SYSTEM
8-4Do-it-yourself
ZX

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.
CHANGING ENGINE COOLANT
cMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in an
appropriate NISSAN Service Manual.cImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
cTo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
Perform the following procedure to open the
heater water cock:
1. Turn the ignition switch ON and set the
temperature control lever to the maxi-
mum hot position. Wait 10 seconds, then
turn the switch OFF.
2. Open the radiator drain plug. Open the
drain plug on the engine water pipe.
3. Open the radiator cap to drain the cool-
ant.
4. Flush the cooling system by running
fresh water through the radiator.
5. Close the radiator drain plug and the

drain plug on the engine water pipe se-
curely.
6. See the ``Technical and consumer infor-
mation'' section for cooling system ca-
pacity. Fill the radiator slowly with the
proper mixture of coolant and water. Fill
the reservoir tank up to the MAX level.
7. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.
8. Start the engine and let it idle until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under
no load. Watch the engine coolant tem-
perature gauge for signs of overheating.
9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level.
10. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.11. Check the radiator drain plug and the
drain plug on the engine water pipe for
any sign of leakage, tighten if neces-
sary.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.
3. Turn off the engine.Wait a few 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
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
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.
