water pump NISSAN PATHFINDER 1999 R50 / 2.G Owners Manual

FUEL FILLER CAPThe fuel filler cap is a screw-on ratcheting
type. Tighten the cap clockwise until ratcheting
clicks are heard.IGasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames orsparks near the vehicle when refuel-
ing.
IFuel may be under pressure. Turn the
cap one-half turn, and wait for any
hissing sound to stop to prevent fuel
from spraying out and possible per-
sonal injury. Then remove the cap.
IDo not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling
may cause fuel over-flow, resulting in
fuel spray and possibly a fire.
IUse only a genuine NISSAN fuel filler
cap as a replacement. It has a built-in
safety valve needed for proper opera-
tion of the fuel system and emission
control system. An incorrect cap can
result in a serious malfunction and
possible injury.
INever pour fuel into the throttle body
to attempt to start your vehicle.
IIf fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.
ITighten until cap clicks, failure to
tighten fuel cap properly may cause
the
malfunction indicator light
(MIL) to illuminate. If this occurs, se-
curely close the fuel filler cap. After
driven for a while, the light should
remain off. If the light remains on,
have the vehicle inspected by an au-
thorized NISSAN dealer.
For additional information, see the
ªMalfunction indicator light (MIL)º in
the ª2. Instruments and controlsº
section.

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit develops a problem, you
will still have braking at two wheels.Vacuum assisted brakeThe brake booster aids braking by using en-
gine vacuum. If the engine stops, you can stop
the vehicle by depressing the brake pedal.
However, greater foot pressure on the brake
pedal will be required to stop the vehicle and
the stopping distance will be longer.Using the brakesAvoid 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.
To help save the brakes and to prevent the
brakes from overheating, before going down a
slope or long grade, reduce speed and down-
shift to a lower gear.Wet brakesWhen 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 until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
IWhile driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
IIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will 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 con-
trol and helps to minimize swerving and spin-ning on slippery surfaces.
Using the systemDepress the brake pedal and hold it down.Do not pump the brake pedal. Doing so
may result in increased stopping
distances.Normal operationThe 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 and releases
hydraulic pressure (like pumping the brakes
very quickly). While the actuator is working,
you may feel a pulsation in the brake pedal
and hear a noise or vibration from the actuator
under the hood. This is normal and indicates
that the anti-lock system is working properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.

Propeller shaft(s):
Check the propeller shaft(s) for damage,
looseness and grease leakage under severe
driving condition (
only).
Propeller shaft:
Apply specified grease to the greasing points
of propeller shafts in accordance with the
maintenance schedule. In the case of driving
in water, greasing should be performed imme-
diately afterwards.
Front wheel bearing grease:
Check the wheel bearing for grease leakage
around grease seals, axial end play and
smooth turning (4x2).
Check the wheel bearing grease condition or
repack these in accordance with the mainte-
nance schedule. In case of frequent driving in
muddy water, the bearing grease inspection
should be performed more frequently (
).
Exhaust system:
Visually check the exhaust pipes, muffler, and
hangers for proper attachment, leaks, cracks,
chafing, abrasion, deterioration, etc. Under
severe driving conditions, inspection should be
performed more frequently.Supplemental air bag, and supplemental
side air bag (if so equipped) systems:
Maintenance for the supplemental air bags or
supplemental side air bags should be done by
an authorized NISSAN dealer.
Automatic Speed Control Device (ASCD)
vacuum hoses:
Check vacuum hose (between ASCD actuator
and ASCD pump) for breakage, cracks or
fracture.
