water pump NISSAN SENTRA 1996 B14 / 4.G Owners Manual

cDriving with vacuum assisted brakes:
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 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 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 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 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
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 prevent-
ing wheel lockup, the system helps the
driver maintain steering control and helps to
minimize 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 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 that 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-

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 Neutral (automatic
transmission 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 until
no 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
cBe careful not to allow your hands,
hair or clothing to come into contact
with, or to get caught in, the running
fan, belts, or fan motor. The fan motor
can start at any time when the cool-
ant temperature is high.
cIf coolant is leaking, the water pump
belt is missing or loose, or the cool-
ing 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.
