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.
WARNING
.Never remove the radiator or cool-
ant 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 VEHI-
CLE OVERHEATS” in the “6. In case
of emergency” section of this man-
ual.
.The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine 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 ratioof 50% anti-freeze and 50% deminer-
alized or distilled water. The use of
other types of coolant solutions may
damage the engine cooling system.
