2003 NISSAN 350Z engine coolant

Automatic transmission P (Park) position
mechanism:On a fairly steep hill check that the
vehicle is held securely with the selector lever in
the P (Park) position without applying any
brakes.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, 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 hoses:Check 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, deterioration
or loose connections.
Brake and clutch fluid levels*:Make sure that
the brake and clutch fluid levels are between the
MAX and MIN lines on the reservoir.
Battery*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Engine drive belts*:Make sure that no belt isfrayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level spot,
turning off the engine and waiting 10 minutes.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Exhaust system:Make 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 ªPrecautions when starting
and drivingº in the ª5. Starting and drivingº
section for exhaust gas (carbon monoxide).)
Underbody:The 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 thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see ªCleaning
exteriorº in the ª7. Appearance and careº sec-
tion.
Fluid leaks:Check under the vehicle for fuel,oil, water or other fluid leaks after the vehicle has
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 imme-
diately.8-4

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions 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) position. For an auto-
matic transmission, move the selec-
tor lever to P (Park) position.
IBe sure the ignition key is OFF or
LOCK when performing any parts re-
placement 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 advised to secure or remove any
loose clothing and any jewelry, suchas rings, watches, etc. before work-
ing 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 to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and the bat-
tery.
IOn gasoline engine models with the
Multiport Fuel Injection (MFI) Sys-
tem, the fuel filter or fuel lines should
be serviced by a NISSAN dealer be-
cause 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 off the engine
and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
IAvoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This ª8. Maintenance and do-it-yourselfº section
gives instructions regarding only those items
which are relatively easy for an owner to perform.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
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/distilled water. The use of other
types of coolant solutions may damage
your engine cooling system.Outside temperature

CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up 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 engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

load, worn suspension or other possible
causes of either condition.
IAlways secure items in the trailer to prevent
load shifts while driving.
IBe certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle's behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance will be somewhat different than under
normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if your vehicle is equipped with automatic
transmission, first apply the parking brakeand block the wheels, and then move the
transmission selector lever into the P (Park)
position. If you move the selector lever to the
P (Park) position before blocking the wheels
and applying the parking brake, the transmis-
sion may get damaged.
IWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending on a long grade, downshift
the transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.
IIf the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
trol to the HOT position.
ITrailer towing consumes more fuel than nor-
mal circumstances.
IAvoid towing a trailer for the first 500 miles
(800 km).
IHave your vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.
IWhen making a turn, your trailer wheels will
be closer to the inside of the turn than yourvehicle wheels. To compensate for this, make
a larger than normal turning radius during the
turn.
ICrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.
IBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.
Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.
ITo maintain engine braking efficiency and
electrical charging performance, do not use
6th gear (manual transmission) or 5th posi-
tion (automatic transmission).
IAvoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.
When towing a trailer, change transmis-9-18
