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 vehicle from mov-
ing. For a manual transmission, move
the shift lever to Neutral. For an auto-
matic transmission, move the shift lever
to ªPº (Park).
IBe sure the ignition key is in the ªOFFº
or ªLOCKº position when performing
any replacement or repair.
IDo not work under the engine hood
while it is hot. Always turn off the engine
and wait until it cools down.
IIf you must work with the engine run-
ning, 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, watch, etc. before
working on your vehicle.
IIf you must run the engine in an en-
closed space such as a garage, be surethere is proper ventilation for exhaust
gases.
INever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
INever connect or disconnect either the
battery or any transistorized component
connector while the ignition key is on.
IAlways apply the parking brake and
block the wheels to prevent the vehicle
from moving.
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.
IFailure to follow these or other common
sense guidelines may lead to serious
injury or vehicle damage.
IImproperly disposed motor oil and/or
other vehicle fluids can hurt the environ-
ment. Always conform to local regula-
tions for disposal of vehicle fluid.
IAvoid direct contact with used engine
oil.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 (anti-freeze/water mix-
ture ratio: 50/50) which will ensure protection
against freezing down to þ30ÉF (þ35ÉC). The
anti-freeze solution contains rust and corro-
sion 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 50% soft water.

The use of other types of coolant solutions
may damage your cooling system.
The radiator is equipped with a pressure cap.
Use a NISSAN genuine cap or its equivalent
when replacement is required.
Never remove the radiator cap when theengine 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.
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.
If the cooling system frequently requires

coolant, have it checked by your NISSAN
dealer.
CHANGING ENGINE COOLANT
IMajor cooling system repairs should be
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.
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

1. Perform the following procedure to open
the heater water cock.
ITurn the ignition key from ªOFFº to ªONº.
IMove the heater or air conditioner tem-
perature control dial to the maximum hot
position then turn the ignition key to
ªOFFº.
2. Open the drain valve and radiator cap.
Open the drain plug 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 drain valve and drain plug se-
curely.
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 ªMAXº level. Then
install the radiator cap and close the air
release plug.
7. Start the engine and warm it up until itreaches 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
ªMAXº level.
9. Check the drain valve and drain plug for
any sign of leakage.

CHECKING ENGINE OIL LEVEL
1. 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 ªHº and
ªLº marks. If the oil level is below the ªLº
mark, remove the oil filler cap and pour
recommended oil through the opening. Do
not overfill.
6. Recheck oil level with dipstick.
IOil level should be checked regularly.
Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered by warranty.IIt is normal to add some oil between
oil changes or during the break-in
period, depending on the severity of
operating conditions.
