8-12Maintenance and do-it-yourself
CHANGING ENGINE COOLANT
If major cooling system repairs are required,
contact a GT-R certified NISSAN dealer. The
service procedures can be found in the appro-
priate 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.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Run the engine until it reaches operating temperature.
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 dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
*1. If the
oil level is below
*2, remove the oil filler cap
ENGINE OIL

and pour recommended oil through the
opening.Do not overfill
*3.
6. Recheck oil level with the dipstick.
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 2014
NISSAN GT-R Warranty Information
Booklet for details including applic-
able exclusions.
CHANGING ENGINE OIL AND FILTER
NOTE:
When replacement is required, contact a
GT-R certified NISSAN dealer for servicing.
WARNING
.Prolonged and repeated contact
with used engine oil may cause skin
cancer.
. Try to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
. Keep used engine oil out of reach of
children.

WARNING
Antifreeze is poisonous and should be
stored carefully in marked containers
out of the reach of children.
Fill the window washer fluid reservoir periodi-
cally. Add window washer fluid when the low
washer fluid warning appears on the vehicle
information display. (
“Low washer fluid
warning” page 2-41)
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s
instructions for the mixture ratio.
Refill the reservoir more frequently when driving
conditions require an increased amount of
window washer fluid.
NOTICE
.
Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the
paint.
. Do not fill the window washer
reservoir tank with washer fluid
concentrates at full strength. Some
methyl alcohol based washer fluid
concentrates may permanently stain
the grille if spilled while filling the
window washer reservoir tank.
NOTE:
Pre-mix washer fluid concentrates with
water to the manufacturer’s recommended
levels before pouring the fluid into the
window washer reservoir. Do not use the window washer reservoir to mix the
washer fluid concentrate and water.
WINDOW WASHER FLUID

.Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
. Make certain the terminal connections are
clean and securely tightened.
. If the vehicle is not to be used for 30 days or
longer, disconnect the negative (−) battery
terminal cable to prevent discharging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.PRECAUTIONS

FLUID LEVEL CHECK
WARNING
. Do not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by the battery is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water for at least 15
minutes and seek medical attention.
. Do not operate the vehicle if the
fluid in the battery is low. Low
battery fluid can cause a higher load
on the battery which can generate
heat, reduce battery life, and in
some cases lead to an explosion.
. When working on or near a battery,
always wear suitable eye protection

replacing the filter, wipe the inside of the air
cleaner housing and the cover with a damp
cloth.
WARNING
.Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops
flame if the engine backfires. If it
isn’t there, and the engine backfires,
you could be burned. Do not drive
with the air cleaner removed, and be
careful when working on the engine
with the air cleaner removed.
. Never pour fuel into the throttle
body or attempt to start the engine
with the air cleaner removed. Doing
so could result in serious injury.
CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form when
rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild detergent.
Then rinse the blade with clear water. If your
windshield is still not clear after cleaning the
blades and using the wiper, replace the blades.
CAUTION
Worn windshield wiper blades can
damage the windshield and impair
driver vision.
Maintenance and do-it-yourself8-21
WINDSHIELD WIPER BLADES

8-24Maintenance and do-it-yourself
If the inside of the disc rotors are cold during the
winter and the surface becomes hot due to a
heavy force being applied repeatedly to the
brakes, cracks may occur near the coolant hole
on the surface of the disc rotor. Cracks may also
occur due to a heavy force being repeatedly
applied to the brakes during high performance
driving. In these cases it may be necessary to
replace the disc rotors or brake pads depending
on the condition of the crack. Contact a GT-R
certified NISSAN dealer for replacement.
ENGINE COMPARTMENT
