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.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo 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.
cDo not open the hood if steam is com-
ing out.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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 water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or 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.6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at a NISSAN
dealer.

The engine cooling system is filled at the factory
with Genuine NISSAN Long Life
Antifreeze/Coolant to provide year-round anti-
freeze and coolant protection. The anti-freeze
solution contains rust and corrosion inhibitors.
Additional engine cooling system additives are
not necessary.
WARNING
cNever remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. See precautions in “If your
vehicle overheats” found in the “In case
of emergency” section of this manual.
cThe radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.

CAUTION
When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant (green) or equivalent
with the proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. The use of other types of coolant
solutions or coolant colors, such as or-
ange, may damage the engine cooling
system.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold.If the coolant level is below
the MIN level, add coolant to the MAX level. If the
reservoir 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 up to the MAX level.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service proce-
dures can be found in the NISSAN Service
Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
cTo avoid the danger of being scalded,
never change the coolant when the en-
gine 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.
cAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
cKeep coolant out of the reach of chil-
dren and pets.Engine coolant must be disposed of prop-
erly. Check your local regulations.
1. Open the radiator drain plug by turning it
counterclockwise.

2. Open the drain plug on the engine block.
3. Open the radiator cap to drain the coolant.
cWaste coolant must be disposed of prop-
erly.
cCheck your local regulations.
4. Flush the cooling system by running fresh
water through the radiator.
5. Close the drain plugs on the radiator and the
engine block securely.6. See the “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 up
to the MAX level.
7. For QG18DE engine only, open and close
the air release plug(s) to release air. Then fill
the radiator again and install the radiator
cap.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 overheating.
9. Stop the engine. After it completely cools
down, refill the radiator up to the filler open-
ing. Fill the engine coolant reservoir tank up
to the MAX level.
10. For QG18DE engine only, open and close
the air release plug(s) to release air. Then fill
the radiator again and install the radiator
cap.
11. Check the drain plugs on the radiator and
the engine block for any sign of leakage. For
QG18DE only, also check the air release
plug for any sign of leakage.
