1996 NISSAN ALTIMA engine overheat

To help prevent damage
cDo not use leaded gasoline.
Deposits from leaded gasoline will se-
riously reduce the three way cata-
lyst's ability to help reduce exhaust
pollutants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the catalyst, causing it to
overheat. Do not keep driving if the
engine misfires, or if noticeable loss
of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly by an
authorized NISSAN dealer.
cAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the three way catalyst.
cDo not race the engine while warming
it up.
cDo not push or tow your vehicle to
start the engine.
Avoiding Collision and Rollover
Failure to operate this vehicle in a safe and
prudent manner may result in loss of control
or an accident. Be alert and drive defen-
sively at all times. Obey all traffic regula-
tions. Avoid excessive speed, high speed
cornering, or sudden steering maneuvers,
because these driving practices could
cause you to lose control of your vehicle.As
with any vehicle, a loss of control could
result in a collision with other vehicles or
objects, or cause the vehicle to roll over,
particularly if the loss of control causes
the vehicle to slide sideways.Be attentive
at all times, and avoid driving when tired.
Never drive when under the influence of
alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt as
outlined in the ``Seat Belts'' section of this
manual, and also instruct your passengers
to do so.
Drinking Alcohol/Drugs and Driving
WARNING
Alcohol in the blood stream reduces
coordination, delays reaction time and
impairs judgement. Driving after drink-
ing alcohol increases the likelihood of
being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident alcohol can
increase the severity of the injury.
Nissan is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol related accidents. Although the local
laws vary on what is considered to be
legally intoxicated, the fact is that alcohol
affects all people differently and most
people underestimate the effects of alcohol.
Remember, drinking and driving don't mix!
And that's true for drugs, too (over the
counter, prescription, and illegal drugs).
Don't drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.

cDriving with vacuum assisted brake:
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required
to stop the vehicle and the stopping
distance will be longer.
cDriving with power assisted steering:
The power assisted steering is designed
to use a hydraulic pump, driven by the
engine, to assist steering.
If the engine stops or drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns or at
low speeds.
cWet brakes:
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one
side during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat-up the brakes. Do this untilthe brakes return to normal. Avoid driving
the vehicle at high speeds until the
brakes function correctly.
cAvoid resting your foot on the brake
pedal while driving. This will overheat the
brakes, wear out the brake linings and
pads faster and reduce gas mileage.
cTo help save the brakes and to prevent
the brakes from overheating, reduce
speed and downshift to a lower gear
before going down a slope or long grade.
Overheated brakes may reduce braking
performance and could result in loss of
vehicle control.
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions or
acceleration could cause the wheels to
skid.The anti-lock brake system installed in
some models controls the brakes at each
wheel so the wheels will not lock when
braking abruptly or when braking on slip-
pery surfaces. The system detects the rota-
tion speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing
wheel lockup, the system helps the driver
maintain steering control and helps to mini-
mize swerving and spinning on slippery
surfaces.
Using the System
Depress the brake pedal and hold it down.
It is not necessary to pump the brake
pedal.
Doing so may result in increased stopping
distances.
Normal operation
The anti-lock brake system will not operate
at speeds below 3 to 6 MPH (5 to 10 km/h)
to completely stop the vehicle. (The speeds
will vary according to road conditions.)
When the anti-lock system senses that one
or more wheels are close to locking up, the
actuator (under the hood) rapidly applies

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power,
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
1. Move the vehicle safely off the road,
apply the parking brake and move the
shift lever to Neutral (automatic transmis-
sion to ``P'').
Do not stop the engine.
2. Turn off the air conditioning. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait untilno steam or coolant can be seen before
proceeding.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water.
WARNING
Be careful not to allow your hands, hair
or clothing to come into contact with,
or to get caught in, the running fan,
belts, or motor fan.
The fan motor can start at any time
when the coolant temperature is high.If coolant is leaking, the water pump
belt is missing or loose, or the cooling
fan does not run, stop the engine.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the res-
ervoir tank if necessary. Have your ve-
hicle repaired at the nearest NISSAN
dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional cooling system addi-
tives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ra-
tio. Examples are shown below:

The use of other types of coolant solu-
tions may damage your cooling system.
The radiator is equipped with a pressure
cap. Use a NISSAN genuine cap or its
equivalent when replacement is re-
quired.
Never remove the radiator cap when the
engine is hot. Wait until the engine andradiator cool down. Serious burns could
be caused by high pressure fluid escap-
ing from the radiator. See precautions in
``If your vehicle overheats'' found in the
``In case of emergency'' section.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir
when the engine is cold. If the coolant level
is below ``MIN'', add coolant up to the
``MAX'' level. If the reservoir is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir up to the ``MAX'' level.

f. Wait 10 seconds before turning ignition
switch ``OFF''.
cManual air conditioning
a. Turn ignition switch ``ON'' and set tem-
perature control lever to the maximum
hot position. Wait 10 seconds then turn
switch ``OFF''.
2. Open the radiator drain plug. Open the
drain plug on the engine water pipe.
3. Open the radiator cap to drain the cool-
ant.
4. Flush the cooling system by running
fresh water through the radiator.
5. Close the radiator drain plug and the
drain plug on the engine water pipe se-
curely.
6. See the ``Technical and consumer infor-
mation'' section for cooling system ca-
pacity. Fill the radiator slowly with the
proper mixture of coolant and water. Fill
the reservoir tank up to the ``MAX'' level.
7. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.8. 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.
9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
``MAX'' level.
10. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.11. Check the radiator drain plug and the
drain plug on the engine water pipe for
any sign of leakage, tighten if neces-
sary.

Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked at a NISSAN dealer or other
competent service facility.
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.
ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to chose the correct quality
and viscosity oil to ensure satisfactory en-
gine life and performance. Nissan recom-
mends the use of a low friction oil (energy
conserving oil) in order to improve fuel
economy and conserve energy. Oils which
do not have the specified quality label
should not be used as they could cause
engine damage.Only those engine oils with the American
Petroleum Institute (API) CERTIFICATION
MARK on the front of the container should
be used. This type of oil supersedes the
existing API SG or SH and Energy Conserv-
ing II categories.
If you cannot find engine oil with the CER-
TIFICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation ``SG'' or ``SH'', or in combina-
tion with other categories (for example,
``SG/CC'' or ``SG/CD'') may also be used if
one with the API CERTIFICATION MARK

or other possible causes of either condi-
tion.
cAlways secure items in the trailer to
prevent load shifts while driving.
cBe 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 tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
cAvoid abrupt starts, acceleration or
stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, ifyou must do so, and if your vehicle is
equipped with an automatic transmis-
sion, first block the wheels and apply the
parking brake, and then move the shift
lever into the ``P'' position. If you move
the shift lever to the ``P'' position before
blocking the wheels and applying the
parking brake, transmission damage
could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine overloading and/or overheating.
cIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
``HOT'' position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for the first 500
miles (800 km).
cHave your vehicle serviced more oftenthan at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be 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.
cCrosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle handling. If
swaying does occur, firmly grip the steer-
ing wheel, steer straight ahead, and im-
mediately (but gradually) reduce vehicle
speed. This combination will help stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
