engine overheat NISSAN 350Z 2004 Owner´s Manual

Aftermarket fuel additivesNISSAN does not recommend the use of any
fuel additives (that is, fuel injector cleaner, oc-
tane booster, intake valve deposit removers,
etc.) which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvent or similar
ingredients that can be harmful to the fuel sys-
tem and engine.Octane rating tipsIn most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, and that part of Texas which is directly
south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the above stated
octane rating, or if you hear steady sparkknock while holding a steady speed on
level roads, have your dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.9-4

transmission, first apply the parking brake
and 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.

When 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.

If 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.

Trailer towing consumes more fuel than nor-
mal circumstances.

Avoid towing a trailer for the first 500 miles
(800 km).

Have your vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.

When making a turn, your trailer wheels willbe closer to the inside of the turn than your
vehicle wheels. To compensate for this, make
a larger than normal turning radius during the
turn.

Crosswinds 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.

Be 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.

To maintain engine braking efficiency and
electrical charging performance, do not use
6th gear (manual transmission) or 5th posi-
tion (automatic transmission).

Avoid 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-
sion oil more frequently. For additional
information, see the “8. Maintenance and
do-it-yourself” section.
