1996 NISSAN QUEST 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.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 rollover,
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.
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 is required to
stop the vehicle and the stopping dis-
tance is longer.
cDriving with the power assisted steer-
ing:
The power assisted steering is designed
to use a hydraulic pump, driven by the
engine, to assist steering.
If the engine stops or the drive belt
breaks, you still have control of the ve-
hicle. 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 is
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 brakepedal to heat up the brakes. Do this until
the 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 overheats the
brakes, wears out the brake linings and
pads faster and reduces 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
sudden acceleration could cause the
wheels to skid.The anti-lock brake system controls the
brakes at each wheel so the wheels do not
lock when braking abruptly or when braking
on slippery surfaces. The system detects the
rotation 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 minimize swerv-
ing 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 does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h) to completely stop the vehicle. (The
speeds vary according to road conditions.)
When the anti-lock system senses one or
more wheels are close to locking up, the
actuator (under the hood) rapidly applies
and releases hydraulic pressure (like pump-
ing the brakes very quickly). While the ac-

CAUTION
Automatic transmission models cannot
be push started. This may cause trans-
mission damage.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
gearshift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner switch. Open
all the windows, move the temperature
control dial to warm and fan control knob
to 4.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.4. Open the 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 to make sure the
cooling fan is running. The radiator hoses
and radiator 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 may 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.

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 an appropriate NISSAN genuine
cap or its equivalent when replacement
is required.
Never remove the radiator cap when the
engine is hot. Serious burns could becaused by high pressure fluid escaping
from the radiator.
Wait until the engine and radiator cool
down. See precautions in ``If your ve-
hicle overheats'' found in the ``In case of
emergency'' section.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check 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 cool-
ant 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 cooling system frequently requires
coolant, have it checked by your NISSAN
dealer.
CHANGING ENGINE COOLANT
Your NISSAN dealer can change the engine
coolant. The service procedure is found in
NISSAN's service manual.
Improper servicing can result in reduced
heater performance and engine
overheating.
WARNING
To avoid danger of being scalded,
never change the coolant when the
engine is hot.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn the engine off.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.5. Remove the dipstick again and check the
oil level. It should be between the H and
L marks. If the oil level is below the L
mark, remove the oil filler cap and pour
recommended oil through the opening.
Do not overfill.
6. Recheck the oil level with the dipstick.

EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Emission control system mainte-
nance
Drive belts* ÐCheck drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace the drive belts if found dam-
aged.
Air cleaner filter ÐUnder normal driving
conditions, the air cleaner filter should be
replaced in accordance with the mainte-
nance schedule. However, driving the ve-
hicle in dusty areas may cause more rapid
clogging of the element. Consequently, the
element may have to be replaced more
frequently.
Vapor lines ÐCheck vapor lines and con-
nections for failure or looseness. If leaks are
found, replace them.
Fuel lines ÐCheck the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any parts if they are
damaged.Fuel filter ÐIf the vehicle is operated
under extremely adverse weather condi-
tions or in areas where ambient tempera-
tures are either extremely low or extremely
high, the filter might become clogged. In
such an event, replace the filter immedi-
ately.
Engine coolant* ÐChanging engine cool-
ant can be performed by your NISSAN
dealer or procedures can be found in the
Service Manual. Improper air relief after
changing coolant can result in reduced
heater performance and overheating.
Engine oil & oil filter* ÐUnder normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs* ÐReplace with new plugs
having the correct heat range.
Timing belt ÐReplace the timing belt for
driving the camshaft.
Chassis and body maintenance
Brake lines & cables ÐCheck the brake
lines and hoses (including brake boostervacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, discs, drums & linings Ð
Check these and the other neighboring
brake components for wear, deterioration
and leaks. Under severe driving conditions,
they may have to be inspected more fre-
quently.
Automatic transmission fluid* ÐCheck
the fluid level and visually inspect for signs
of leakage.
Under severe driving conditions, the fluid
should be replaced at the specified interval.
Steering gear & linkage, axle & suspen-
sion parts, and drive shaft boots Ð
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, more frequent inspection should be
performed.
Steering linkage ball joints & front sus-
pension ball joints ÐCheck the ball joints
for damage, looseness and grease leakage.

Incorrect ignition timing results in knocking,
after-run, and/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 combination
with other categories (for example, SG/CC
or SG/CD) may also be used if one with the

Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and it is properly
installed.
CAUTION
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
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 are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid 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, if
you must do so, first block the wheels
and apply the parking brake, and then
move the transmission gearshift lever
into the P (Park) position. If you move the
shift lever to the P (Park) position before
blocking the wheels and applying the
parking brake, transmission damage
could occur.
cWhen going down a hill, shift into a lowergear 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 the air
conditioner off. Coolant heat can be ad-
ditionally vented by opening the win-
dows, switching the fan control dial to
high and setting the temperature control
dial to the WARM position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for the first 500
miles (800 km) of the vehicle's life.
cHave your vehicle serviced more often
than 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 adversely
