2008 NISSAN 350Z engine

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

Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral) position. For automatic
transmission models, move the se-
lector lever to P (Park).

Be sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.

If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.

It is advisable to secure or remove
any loose clothing and remove anyjewelry, such as rings, watches, etc.
before working on your vehicle.

Always wear eye protection when-
ever you work on your vehicle.

If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.

Never 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.

Keep smoking materials, flame and
sparks away from the fuel tank and
battery.

On gasoline engine models with the
multiport fuel injection (MFI) system,
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

Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.

Avoid contact with used engine oil
and coolant. Improperly disposed en-
gine oil, engine coolant and/or other
vehicle fluids can damage the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.

Never connect or disconnect the bat-
tery or any transistorized component
while the ignition switch is in the ON
position.

Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.

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.
WARNING

Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator
cool down. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator. See precau-
tions in “If your vehicle overheats”
found in the “6. In case of emer-
gency” section of this manual.

The radiator is equipped with a pres-
sure type radiator cap. To prevent
engine damage, use only a genuine
NISSAN radiator cap.

ized water/distilled water. The use of
other types of coolant solutions may
damage your engine cooling system.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN
1, add coolant up to the MAX
2
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 radia-
tor, fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank up
to the MAX
