1998 NISSAN FRONTIER Owners Manual

Floor mat positioning aid
(Driver side only)
Some models include a floor mat pin to act
as a floor mat positioning aid. NISSAN floor
mats have been specially designed for your
vehicle model. The driver's side floor mat
has a grommet hole incorporated in it. Po-
sition the mat by placing the floor mat pin
through the floor mat grommet hole while
centering the mat in the footwell. Periodi-
cally check to make certain that the mats
are properly positioned.
Floor mats
The use of genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior.No
matter what mats are used, be sure they
are fitted for your vehicle and are prop-
erly positioned in the footwell to prevent
interference with pedal operation.Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.
Seat belts
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely before using them.
WARNING
Do not allow wet belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents since these may se-
verely weaken the seat belt webbing.
Most common factors contributing
to vehicle corrosion.
1. The accumulation of moisture-retaining
dirt and debris in body panel sections,
cavities, and other areas.
2. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor traffic accidents.
Environmental factors influence the
rate of corrosion.
Moisture
The accumulation of sand, dirt and water on
the underside of the body accelerates cor-
rosion. Floor sections which have snow and
ice trapped under the floor matting will not
dry.
Relative humidity
Corrosion will be accelerated:
cin areas of high relative humidity.
cin areas where the temperatures stay
above freezing.
cwhere atmospheric pollution exists.
cwhere road salt is used.AAI0500
CORROSION PROTECTION
7-4Appearance and care
ZX

Temperature
A temperature increase accelerates the rate
of corrosion to those parts which are not
well ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disintegra-
tion of paint surfaces.
To protect your vehicle from corro-
sion:
cwash and wax your vehicle often to keep
the vehicle clean.
calways check for minor damage to the
paint and repair it as soon as possible.
ckeep drain holes at the bottom of the
doors and tailgate open to avoid water
accumulation.
ccheck the underbody and inside the
pick-up box. If any sand, dirt or salt is
accumulated, wash it off with water as
soon as possible.
CAUTION
cNEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing with a hose. Re-
move dirt with a vacuum cleaner or
broom.
cNever allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, consult an authorized NISSAN
dealer.

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral). For an automatic trans-
mission, move the shift lever to P
(Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.cAlways wear eye protection when-
ever you work on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, the fuel filter or fuel lines
should be serviced by an authorized
NISSAN dealer because the fuel
lines are under high pressure even
when the engine is off.
CAUTION
cDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
cAvoid contact with used motor oil.
Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local regulations for disposal of ve-
hicle fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional engine cooling system ad-
ditives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ratio
of 50% anti-freeze and 50% distilled
water. The use of other types of coolant
solutions may damage the engine cool-
ing system.

WARNING
cNever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Seriousburns could be caused by high pres-
sure fluid escaping from the radia-
tor. See precautions in ``If your ve-
hicle overheats'' found in the ``In
case of emergency'' section of this
manual.
cThe radiator is equipped with a pres-
sure cap. Use only a genuine NIS-
SAN cap as it's replacement.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below the MIN level, add coolant 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
coolant 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.

ENGINE COOLING SYSTEM

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.
CHANGING ENGINE COOLANT
cMajor cooling system repairs should be
performed by an authorized NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.cImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
cTo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
1. Open the radiator drain valve. Open the
drain plug on the engine block.
2.
Open the radiator cap to drain the coolant.
3. Flush the cooling system by running
fresh water through the radiator.
4. Close the radiator drain valve and drain
plug on the engine block securely.
5. See ``Capacities and recommended
fuel/lubricants'' in the ``Technical and
consumer information'' section for cool-
ing system capacity. Fill the radiator
slowly with the proper mixture of coolant
and water. Fill the reservoir tank slowly
up to the MAX level.
