2004 NISSAN 350Z engine

Platinum-tipped spark plugsIt is not necessary to replace the platinum-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance schedule but, do not
reuse them by cleaning or regapping.
Always replace with recommended
platinum-tipped spark plugs.To remove the filter from the air cleaner, pull off
the lock pins
1
and pull the unit upward
2.
The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the Service and Maintenance
Guide. When replacing the filter, wipe the inside
of the air cleaner housing and the cover with a
damp cloth.
WARNING

Operating the engine with the air
cleaner removed can cause you orothers to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.

Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.

CAUTION

After wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when
the engine hood is opened.

Make sure the wiper blade contacts
the glass, otherwise the arm may be
damaged from wind pressure.

Worn windshield wiper blades can
damage the windshield and impair
driver vision.CLEANINGIf your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your wind-
shield is clean if beads do not form when rinsing
with clear water.
Clean the blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Thenrinse the blade with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.WINDSHIELD WIPER BLADES

CHECKING PARKING BRAKEFrom the released position, pull the parking
brake lever up slowly and firmly. If the number of
clicks is out of the range listed above, see your
NISSAN dealer.
CHECKING BRAKE PEDALWith the engine running, check the distance
between the upper surface of the pedal and the
metal floor. If it is out of the range shown above,
see your NISSAN dealer.Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe disc brake pads on your vehicle have au-
dible wear indicators. When a brake pad re-
quires replacement, it will make a high pitched
scraping or screeching sound when the vehicle
is in motion whether or not the brake pedal is
depressed. Have the brakes checked as soon as
possible if the wear indicator sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect
the function or performance of the brake system.
Proper brake inspection intervals should
be followed.For additional information, see the
appropriate maintenance log shown in the Ser-
vice and Maintenance Guide.

BRAKE BOOSTERCheck the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake pedal
movement (distance of travel) remains the
same from one pedal application to the next,
continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, see your
NISSAN dealer.
CAUTION
Never use a fuse of higher or lower
amperage rating than that specified on
the fuse box cover. This could damage
the electrical system or cause a fire.
ENGINE COMPARTMENTIf any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition key and headlight switch
are OFF.
2. Open the engine hood and remove the cover
on the battery and the fuse/fusible link holder.
3. Remove the fuse/fusible link holder cover.
4. Remove the fuse with the fuse puller.
5. If the fuse is open, replace it with a new fuse.
6. If a new fuse also opens, have the electrical

HEADLIGHTS
ReplacingIf replacement is required, see a NISSAN dealer.
Xenon headlight bulb:
WARNINGHIGH VOLTAGE
When xenon headlights are on, they
produce a high voltage. To prevent an
electric shock, never attempt to modify
or disassemble the headlight assembly.
Always have your xenon headlights re-
placed at a NISSAN dealer. For addi-
tional information, see “Headlight and
turn signal switch” in the “2. Instru-
ments and controls” section.
Halogen headlight bulb:
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. A
bulb can be replaced from under the engine
compartment without removing the headlight
assembly.
CAUTION

High pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.

When handling the bulb, do not touch
the glass envelope.

Do not touch the bulb.

Use the same number and wattage as
originally installed:
Bulb no. (Wattage)
D2R (35W) - Xenon low-beam
H7 (55W) - High-beam
or
H7 (55W) - Halogen low-beam
H1 (55W) - High-beam

Do not leave the bulb out of the
headlight reflector for a long period
of time as dust, moisture, and smoke
may enter the headlight body and
affect the performance of the head-
light.

CAPACITIES AND
RECOMMENDED FUEL/
LUBRICANTS9-2
Technical and consumer information


04.1.22/Z33-D/V5.0


FUEL RECOMMENDATIONUse unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:

Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.

Avoid full throttle driving and abrupt accelera-
tion.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso-
line is recommended.
CAUTION
Using a fuel other than that specified
could adversely affect the emission con-
trol devices and systems, and could also
affect the warranty coverage.Under no circumstances should a
leaded gasoline be used, since this will
damage the three-way catalyst.
Reformulated gasolineSome fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. NISSAN
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
NISSAN does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your NISSAN cannot be readily
determined. If in doubt, ask your service station
manager.
If you use oxygenate-blend gasoline, please take
the following precautions as the usage of such
fuels may cause vehicle performance problems
and/or fuel system damage.

The fuel should be unleaded and have
an octane rating no lower than thatrecommended for unleaded gasoline.

If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)

If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are
suitable for use in NISSAN vehicles.
If any undesirable driveability problems such as
engine stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
