This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue) . The life expec-
tancy of the factory-fill coolant is 24,000 miles
(38,400 km) or 2 years. Mixing any other type of
coolant or the use of non-distilled water will
reduce the life expectancy of the factory-fill
coolant. Refer to the GT-R Service and Main-
tenance Guide for more details.
If the cooling system frequently requires
coolant, it is recommended you have it
checked by a GT-R certified NISSAN deal-
er.
Check that the level of coolant is between MAX
and MIN on the pressurized radiator reservoir. If
the level is below the midpoint, the amount of
coolant circulating may be insufficient for max-
imum vehicle performance, possibly causing
engine overheating or other trouble.
For the coolant level and mixture ratio when
engaging in performance driving, see
ªCoolant level and mixture ratioº page
GTR-14.
Except for NISMO models:
If it is difficult to determine the midpoint between
MAX and MIN, remove the coolant reservoir cap
and look inside through the opening to check
that the coolant level is above the divider
*3
between the top half and bottom half of the pressurized coolant reservoir.
NOTICE
.
The coolant reservoir is equipped
with a pressure type cap, and the
radiator is equipped with a non-
pressure type cap. Do not switch
the radiator filler cap and the cool-
ant reservoir cap. Doing so will
cause substandard cooling perfor-
mance and overheating.
. If you have added only water as the
coolant in an emergency, change it
to a coolant mixture ratio specified
as soon as possible.
CHANGING ENGINE COOLANTGUID-851EDD89-D9EC-4EE0-B833-ADAF4D8D3C6FIf major cooling system repairs are required, it is
recommended you contact a GT-R certified
NISSAN dealer. The service procedures can
be found in the appropriate NISSAN Service
Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
.To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator filler cap
and the coolant reservoir cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator and
reservoir.
. Avoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
. Keep coolant out of reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
