1996 NISSAN PATHFINDER heating

If your vehicle is overheating indicated by an
extremely high temperature gauge reading, or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
To avoid the danger of being burned,
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 the neutral position (automatic
transmission to ªPº).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-
tioner temperature control to ªmaximum
hotº and fan control to ªhigh speedº.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.4. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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
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 radiator
should not leak water.
IBe careful not to allow your hands,
hair or clothing to come into contact
with, or to get caught in, the running
fan or belts.
IIf coolant is leaking, the cooling fan
belt is missing or loose or the cooling
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 reservoir
tank if necessary. Have your vehicle re-
paired at the nearest NISSAN dealer.

1. Perform the following procedure to open
the heater water cock.
ITurn the ignition key from ªOFFº to ªONº.
IMove the heater or air conditioner tem-
perature control dial to the maximum hot
position then turn the ignition key to
ªOFFº.
2. Open the drain valve and radiator cap.
Open the drain plug on the engine block.
3. Open the air release plug to drain the
coolant.4. Flush the cooling system by running fresh
water through the radiator.
5. Close the drain valve and drain plug se-
curely.
6. See the ªTechnical informationº section for
cooling system capacity.
Fill the radiator slowly with the proper mix-
ture of coolant and water. Fill the reservoir
tank slowly up to the ªMAXº level. Then
install the radiator cap and close the air
release plug.
7. Start the engine and warm it up until itreaches 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
opening. Fill the reservoir tank up the
ªMAXº level.
9. Check the drain valve and drain plug for
any sign of leakage.

Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ªspark knockº. (ªSpark
knockº 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 encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
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.

Tire pressures
IWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pressure
indicated on the tire placard (affixed to the
glove box lid).
ITrailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer and tire manufac-
turers' specifications.
Safety chain
Always use a suitable chain between your
vehicle and the trailer. The chain should be
crossed and should be attached to the hitch,
not to the vehicle bumper or axle. Be sure to
leave enough slack in the chain to permit
turning corners.
Trailer lights
Trailer lights should comply with Federal
and/or local regulations.
When wiring vehicle for towing connection,
connect stop and tail light pickup into the
vehicle electrical circuit at point between
the sensor and stop light switch or light
switch.
Trailer brakes
If your trailer is equipped with a braking sys-
tem, make sure it conforms to Federal and/or
local regulations and that it is properly in-
stalled.
Never connect a trailer brake system
directly to the vehicle brake system.
Trailer towing tips
In order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability and
braking performance will be somewhat differ-
ent than under normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on aslope is not recommended; however, if you
must do so, and if your vehicle is equipped
with automatic transmission, first block the
wheels and apply the parking brake, and
then move the transmission shift lever into
the ªPº position. If you move the shift lever
to the ªPº position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
IWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating.
However, for long steep grades, do not stay in
1st or 2nd gear when driving above 35 MPH
(56 km/h).
IIf 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
control to high and setting the temperature
control to the ªHOTº position.
ITrailer towing requires more fuel than nor-
mal circumstances.
