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.

Type A
Add fluid when the low washer fluid warning
light comes on. Add a washer solvent to the
water for better cleaning. In the winter season,
add a windshield washer anti-freeze. Follow
the manufacturer's instructions for the mixture
ratio.
Type B
To check the fluid level, use your finger to plug
the center hole of the cap/tube assembly (as
shown above), then remove it from the tank. If
there is no fluid in the tube, add fluid.Add a washer solvent to the water for better
cleaning. In the winter season, add a wind-
shield washer anti-freeze. Follow the manufac-
turer's instructions for the mixture ratio.
Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the paint.
Anti-freeze is poisonous and should be
stored carefully marked containers out
of the reach of children.

your vehicle is held securely with the selector
lever in the ªPº position without applying any
brakes.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Windshield washer fluid*Check that there is
adequate fluid in the tank.
Engine coolant level*Check the coolant level
when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure
the hoses have no cracks, deformation, rot or
loose connections.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
ªMAXº and ªMINº lines on the reservoir.
Battery*Check the fluid level in each cell. It
should be between the ªMAXº and ªMINº lines.
Engine drive belts*Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level spot and turning off the
engine. (Be sure to wait a few minutes to allowthe oil to drain back into the sump.)
Power steering fluid level* and linesCheck
the level when the fluid is cold and the engine
is turned off. Check the lines for proper attach-
ment, leaks, cracks, etc.
Automatic transmission fluid level*Check
the level after putting the selector lever in ªPº
with the engine idling.
Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound of
the exhaust seems unusual or there is a smell
of exhaust fumes, immediately locate the
trouble and correct it. (See the carbon monox-
ide warning in the ªStarting and drivingº sec-
tion)
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. See the ªAppearance and Interior
Careº section for additional information.
Fluid leaksCheck under the vehicle for fuel,
oil, water or other fluid leaks after the vehiclehas been parked for a while. Water dripping
from the air conditioner after use is normal. If
you should notice any leaks or if gasoline
fumes are evident, check for the cause and
have it corrected immediately.

EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following
items with ª*º is found in the ªDo-it-
yourself operationsº section.
Emission control system
maintenance
Drive belts*Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filterUnder normal driving condi-
tions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
Vapor linesCheck vapor lines and connec-
tions for failure or looseness. If leaks are
found, replace the lines.
Fuel linesCheck the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are either
extremely low or extremely high, the filtermight become clogged. In such an event,
replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil & oil filter*Under normal driving
conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*Replace with new plugs having
the correct heat range.
Timing belt
Replace the timing belt for driving the cam-
shafts.
Chassis and body maintenance
Brake lines & cablesCheck the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads, discs, drums & liningsCheck
these and the other neighboring brake compo-
nents for wear, deterioration and leaks. Under
severe driving conditions, they may have to be
inspected more frequently.Manual and automatic transmission, trans-
fer & differential gear oilVisually inspect for
signs of leakage and replace oil for limited-slip
differential. Under severe driving conditions,
the oil should be replaced at the specified
interval.
Steering gear & linkage, axle & suspension
parts & drive axle shaft bootsCheck for
damage, looseness and leakage of oil or
grease. Under severe driving conditions, more
frequent inspection should be performed.
Steering linkage ball joints & front suspen-
sion ball jointsCheck the ball joints for dam-
age, looseness and grease leakage. Under
severe driving conditions, more frequent in-
spection should be performed.
Propeller shaft(s)Check the propeller
shaft(s) for damage, looseness and grease
leakage under severe driving condition
(only).
Propeller shaft greaseApply specified
grease to the greasing points of propeller
shafts in accordance with the maintenance
schedule. In the case of driving in water,
greasing should be performed immediately
afterwards.
