drain bac�b into t�fe oil pan before c�fec�bing t�fe
oil.
Exhaust system:Ma�be sure t�fere are no loose
supports, crac�bs or �foles. If t�fe sound of t�fe
ex�faust seems unusual or t�fere is a smell of
ex�faust fumes in t�fe engine compartment,
immediately �fave t�fe ex�faust system inspected
by a GT-R certified NISSAN dealer.

Fluid leaks: C�fec�b under t�fe ve�ficle for fuel,
oil, water or ot�fer fluid lea�bs after t�fe ve�ficle �fas
been par�bed for a w�file. Water dripping from t�fe
air conditioner after use is normal. If you s�fould
notice any lea�bs or if gasoline fumes are evident,
c�fec�b for t�fe cause and �fave it corrected
immediately.
Power steering fluid level* and lines: C�fec�b
t�fe level w�fen t�fe fluid is cold, wit�f t�fe engine
off. C�fec�b t�fe lines for proper attac�fment, lea�bs,
crac�bs, etc.
Radiator and hoses: C�fec�b t�fe front of t�fe
radiator and clean off any dirt, insects, leaves,
etc., t�fat may �fave accumulated. Ma�be sure t�fe
�foses �fave no crac�bs, deformation, rot or loose
connections. Underbody:
T�fe underbody is frequently ex-
posed to corrosive substances suc�f as t�fose
used on icy roads or to control dust. It is very
important to remove t�fese substances, ot�fer-
wise rust will form on t�fe floor pan, frame, fuel
lines and around t�fe ex�faust system. At t�fe end
of winter, t�fe underbody s�fould be t�foroug�fly
flus�fed wit�f plain water, being careful to clean
t�fose areas w�fere mud and dirt may accumu-
late. (“Underbody” page 7-5)

damage to t�fe ve�ficle. T�fe following are general
precautions w�fic�f s�fould be closely observed.
WARNING
.
Park the vehicle on a level surface,
apply the parking brake securely
and block the wheels to prevent
the vehicle from moving. Move the
shift lever to the
&Pposition.
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
. It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
MAINTENANCE PRECAUTIONS

.If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always
disconnect the negative battery
cable before working near the fan.
. The fuel filter or fuel lines should be
serviced by a GT-R certified NISSAN
dealer because the fuel lines are
under high pressure even when the
engine is off.CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly
disposed engine oil, coolant, and/
or other vehicle fluids can damage
the environment. Always conform to
local regulations for disposal of
vehicle fluid.
NOTICE
.Never connect or disconnect the
battery or any transistorized com-
ponent while the ignition switch is

could be caused by high pressure
fluid escaping from the radiator.
(
“If your vehicle overheats”
page 6-8)
. The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system ad-
ditives such as radiator sealer. Ad-
ditives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling sys-
tem.
. When adding or replacing coolant,
be sure to use only Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) is pre-diluted to provide
antifreeze protection to í348 F
(í378C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) concentrate follow-
ing the directions on the container.
If an equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/ Coolant (blue) is used, fol-
low the coolant manufacture’s
instructions to maintain minimum
antifreeze protection to í348 F
(í378C) . The use of other types of
coolant solutions other than Genu- ine NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent may
damage the engine cooling system.
. The life expectancy of the factory-fill
coolant is 24,000 miles (38,400 km)
or 2 years. Mixing any other type of
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) ,
including Genuine NISSAN Long
Life Antifreeze/Coolant (green) , or
the use of nondistilled water will
reduce the life expectancy of the
factory-fill coolant. Refer to the
GT-R Service and Maintenance
Guide for more details.

Maintenance and do-it-yourself8-11

8-12Maintenance and do-it-yourself
This vehicle contains Genuine N�fSSAN Lon�b
Life Antifreeze/Coolant (blue) . The life expec-
tancy of the factory-fill coolant is 24,000 miles
(38,400 km) or 2 years. Mixin�b 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, have it checked by a GT-R certified
NISSAN dealer.
Check that the level of coolant is between MAX
and M�fN on the pressurized radiator reservoir. �ff
the level is below the midpoint, the amount of
coolant circulatin�b may be insufficient for max-
imum vehicle performance, possibly causin�b
en�bine overheatin�b or other trouble.
For the coolant level and mixture ratio when
en�ba�bin�b in performance drivin�b, see
“Coolant level and mixture ratio” pa�be
GTR-15.
Except for NISMO models:
�ff it is difficult to determine the midpoint between
MAX and M�fN, remove the coolant reservoir cap
and look inside throu�bh the openin�b 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 COOLANT
�ff major coolin�b system repairs are required,
contact a GT-R certified N�fSSAN dealer. The
service procedures can be found in the appro-
priate N�fSSAN 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.
En�bine coolant must be disposed of properly.
Check your local re�bulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and a\f\flythe \farking brake.
\b. Run the engine until it reaches o\ferating tem\ferature.
3. Turn off the engine. Wait at least 5
minutes for the oil to drain back into
the oil pan before checking the oil.
4. Remove the di\fstick and wi\fe it clean. Reinsert it all the way.
5. Remove the di\fstick again and check the oil level. It should be within the range
*1. If the
oil level is below
*2, remove the oil filler ca\f and \four recommended oil through the
o\fening.
Do not overfill
*3.
6. Recheck oil level with the di\fstick.
NOTE:
. It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the
severity of operating conditions. More
engine oil is consumed by frequent
acceleration/deceleration especially
when the engine rpm is high. If your
rate of oil consumption increases sud-
denly or without explanation, NISSAN
recommends that you have your vehicle
inspected by a GT-R certified NISSAN
dealer.
. When the vehicle is delivered, the
engine oil is set to 0.39 in (10 mm)
below the H mark for optimal high
performance driving. The engine oil can
be filled up to the H mark if perfor-
mance driving is not engaged.NOTICE
.Mobil 1 (0W-40) (100% synthetic) is
the factory fill oil. The VR38 engine
with its plasma-sprayed bores was
developed using this oil. NISSAN
cannot ensure proper engine opera-
tion and durability if other 0W-40
synthetic oil is used. If Mobil 1 (0W-
40) is not available, Mobil 1 (10W-
40) (100% synthetic) may be used;
however, some performance loss
may be noticed.
. Oil level should be checked regu-
larly. Operating the engine with an
insufficient amount of oil can da-
mage the engine. See the 2015
NISSAN GT-R Warranty Information
Booklet for details including applic-
able exclusions.
