The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
WARNING
●
Never remove the radiator cap when the en-
gine is hot. Wait until the engine and radia-
tor cool down. Serious burns could be
caused by high pressure fluid escaping from
the radiator. See precautions in “IF YOUR
VEHICLE OVERHEATS” in the “6. In case of
emergency” section of this manual.
●
The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, 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% antifreeze and
50% demineralized or distilled water. The use
of other types of coolant solutions may damage
the engine cooling system.

CHECKING ENGINE COOLANT LEVEL
Check the coolant level
in the reservoir when the
engine is cold.
If the coolant level is below MIN
s
2
, open the reservoir tank cap and add coolant
up to the MAX
s
1
level. If the reservoir tank is
empty, check the coolant level in the radiator
when 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 tank up to the MAX level
s
1
.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI dealer.
