2000 NISSAN FRONTIER engine

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power, or
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo 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.
IDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
gearshift lever to N (Neutral), or the au-
tomatic transmission into P (Park).
Do not stop the engine.
2.
Turn off the air conditioner (if so
equipped). Open all of the windows,
move the heater or air conditioner tem-perature control to maximum hot and fan
control to high speed.
3. 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 r/min)
until the temperature gauge indicator re-
turns to normal.
4. 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.
5. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing, or the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, engine belts or
the engine cooling fan. The engine
cooling fan can start at any time when
the coolant temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at 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
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the shift lever
to P (Park).
IBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
INever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
INever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
IIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever 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.
IKeep smoking materials, flame and
sparks away from fuel tank and bat-
tery.
IOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should
beserviced by an authorized NISSANdealer because the fuellines are un-
der high pressure even when the
engine is off.
CAUTION
IDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
IAvoid contact with used engine oil.
Improperly disposed engine oil and/
or other vehicle fluids can damage
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,
genuine NISSAN anti-freeze coolant solu-
tion. The anti-freeze solution contains rust
and corrosion inhibitors, therefore additional
engine cooling system additives 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% Genuine Nissan Anti-freeze
coolant or equivalent and 50% dem-
ineralized or distilled water. The use of
other types of coolant solutions may
damage the engine cooling system.

WARNING
INever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radiator.
See precautions in ``If your vehicle
overheats'' found in the ``In case of
emergency'' section of this manual.
IThe radiator is equipped with a pres-
sure type radiator cap. To prevent
engine damage, use only a genuine
NISSAN radiator cap.
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.

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.CHANGING ENGINE COOLANT
IMajor cooling system repairs should be
performed by an authorized NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Ser-
vice Manual.
IImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
ITo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
INever 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 plugs 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.

8. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine two or three times
under no load. Watch the engine coolant
temperature gauge for signs of overheat-
ing.9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up 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 drain valve on the radiator
and drain plugs on the engine block for
any sign of leakage.CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.
3. Turn off the engine.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.
