1996 NISSAN PATHFINDER engine overheat

coolant, have it checked by your NISSAN
dealer.
CHANGING ENGINE COOLANT
IMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.IImproper servicing can result in reduced
heater performance and engine overheat-
ing.
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. 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.
