1997 NISSAN PATHFINDER engine coolant

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.

If the engine 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.

perature control dial to the maximum hot
position then turn the ignition key to
ªOFFº.
2. Open the radiator drain plug and radiator
cap.
Open the drain plugs 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 radiator drain plug and engine
block drain plugs securely.
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 it
reaches 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 radiator drain plug and engine
block drain plugs 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, addfluid. 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 ra-
tio.
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.
