2004 NISSAN PATHFINDER engine overheat

tioner temperature control to maximum hot
and fan control to high speed.
3. If engine overheating is caused by climbing a
long hill on a hot day, run the engine at a fast
idle (approximately 1,500 rpm) until the tem-
perature gauge indication returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Do not open the
hood until no further steam or coolant can be
seen.
5. Open the engine 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 leaking,
the cooling fan 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, the
cooling fan, or drive belt.

The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at the
nearest NISSAN dealer.For information about towing your vehicle behind
a recreational vehicle (RV), refer to “Flat towing”
in the “9. Technical and consumer information”
section of this manual.
When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must
be followed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from your NISSAN dealer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing. To
assure proper towing and to prevent accidental
damage to your vehicle, NISSAN recommends
having a service operator tow your vehicle. It is
advisable to have the service operator carefully
read the following precautions:
WARNING

Never ride in a vehicle that is being
towed.

Never get under your vehicle after it
has been lifted by a tow truck.TOWING YOUR VEHICLE

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
CAUTION
When adding or replacing the coolant,
be sure to use only Genuine NISSAN
Long Life Anti-freeze Coolant or an
equivalent with the proper mixture ratio
of 50% anti-freeze and 50% demineral-
ized water/distilled water. The use of
other types of coolant solutions may
damage your engine cooling system.Outside tempera-

WARNING

Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator. Wait
until the engine and radiator cool
down. See “If your vehicle overheats”
in the “6. In case of emergency” sec-
tion.

The radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck 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 radia-
tor, 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 engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by your NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.

Improper servicing can result in reduced
heater performance and engine overheating.
WARNING

To avoid the danger of being scalded,
never change the coolant when the
engine is hot.

Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

Avoid direct skin contact with used
coolant. If skin contact is made, washthoroughly with soap or hand cleaner
as soon as possible.

Keep coolant out of reach of children
and pets.

3. Open the air release plug(s) to drain the
coolant.
4. Flush the cooling system by running fresh
water through the radiator.

Waste coolant must be disposed of
properly.

Check your local regulations.
5. Close the radiator drain plugs and engine
block drain plugs securely.
6. See the “9. Technical and consumer informa-
tion” section for cooling system capacity.
Fill the radiator slowly with the proper mixture
of coolant and water. Fill the reservoir tank
slowly up to the MAX level. Then install the
radiator cap and close the air release plug(s).
7. Start the engine and warm it up until it
reaches normal operating temperature. Then
race the engine 2 or 3 times under no load.
Watch the coolant temperature gauge for
signs of overheating.
8. Stop the engine. After it completely cools
down, refill the radiator up to the filler open-
ing. Fill the reservoir tank up the MAX level.
9. Check the radiator drain plug and engine
block drain plugs for any sign of leakage.
CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and apply
the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Rein-
sert 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 recom-
mended oil through the opening. Do not
overfill.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
changes or during the break-in period, de-
pending on the severity of operating con-
ditions.
CAUTION
Oil level should be checked regularly.

unleaded gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number
(VQ35DE engine). However, you may use un-
leaded gasoline with an octane rating as low as
85 AKI (Anti-Knock Index) number in these high
altitude areas [over 4,000 ft (1,219 m)] such as:
Colorado, Montana, New Mexico, Utah, Wyo-
ming, northeastern Nevada, southern Idaho,
western South Dakota, western Nebraska, and
that part of Texas which is directly south of New
Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at aNISSAN dealer or other competent service fa-
cility.
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.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.
However, for long steep grades, do not stay in
1st or 2nd gear when driving above 35 MPH (56
km/h).

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
trol to the HOT position.

Trailer towing requires more fuel than normal
circumstances.

Avoid towing a trailer for the first 500 miles
(805 km).

Have your vehicle serviced more often than at
intervals specified in the recommended Main-
tenance Schedule in the “NISSAN Service
and Maintenance fluid”.

When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this, makea larger than normal turning radius during the
turn.

Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.

Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.
Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.

To maintain engine braking efficiency and
electrical charging performance, do not use
sixth gear (manual transmission) or fifth posi-
tion (automatic transmission).

Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.
When towing a trailer, the transmission
oil/fluid should be changed more fre-quently. For additional information, see
the “8. Maintenance and do-it-yourself”
section earlier in this manual.
FLAT TOWINGTowing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a ve-
hicle behind a recreational vehicle, such as a
motor home.
CAUTION

Failure to follow these guidelines
can result in severe transmission
damage.

Whenever flat towing your vehicle,
always tow forward, never backward.

DO NOT tow any automatic transmis-
sion vehicle with all four wheels on
the ground (flat towing). Doing so
WILL DAMAGE internal transmission
parts due to lack of transmission lu-
brication.

fer to “Towing Recommended by
