2014 NISSAN GT-R engine coolant

GTR-6GT-R Overview
SUSPENSION
Genuine GT-R special suspension
Use only genuine GT-R special suspension
components.
Using non-genuine GT-R suspension compo-
nents can affect vehicle performance and may
cause body damage when driving depending on
the road conditions.
GT-R TRACK PACK option Genuine special
suspension (if so equipped)
Models with the TRACK PACK option are
equipped with specially tuned shock absorbers,
springs and suspension that optimizes perfor-
mance driving.
BRAKE PAD AND DISC ROTOR
Genuine GT-R brake pads and disc rotors
Use only genuine GT-R brake pads and disc
rotors.
This vehicle is equipped with cross-drilled
floating rotors and radial-mounted six-piston
monoblock calipers. This helps to achieve
excellent stopping performance and fade-resis-
tance.
Using non-genuine GT-R brake pads or rotors
can affect vehicle braking performance and the
operation of the ABS and VDC system.
Replacement of brake pads and disc
rotors
NISSAN generally recommends to replace all
four sets of brake pads and disc rotors at the
same time to maintain maximum brake perfor-
mance.
However, replacing only the brake pads may be
allowed in some cases (four wheels or only front
wheels depending on the conditions). A GT-R
certified technician must inspect the vehicle and
determine that only the brake pads need to be
replaced. In this case, replacing all brake pads
and disc rotors as a set is not necessary.
Note that the replacement of brake pads and the
disc rotors as a set on all four wheels should be
performed when a GT-R certified technician
determines that this is the correct repair.
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.
EXHAUST MUFFLER AND TRUNK
CARPET
Genuine GT-R special exhaust muffler and
trunk carpet
Use only the genuine GT-R special exhaust
muffler and trunk carpet.
The GT-R exhaust system is designed to provide
the maximum vehicle performance and to
protect the vehicle from high exhaust gas
temperatures.
If non-genuine GT-R specification parts are
used it is possible that the muffler or other
exhaust system parts will deform and cause
damage to the underbody. Non-genuine GT-R
specification parts can also affect vehicle
performance and possibly lead to turbocharger,
engine or power train related parts including
transmission, damage.
Also, do not remove the trunk carpet from the
vehicle for any reason. The carpet insulates the
vehicle interior from the heat of the muffler and
from the noise of the transmission.

The information and specifications in this
section apply only when engaging in
performance driving.
The following information applies only if you

certified NISSAN dealer.PRECAUTIONS ON PERFORMANCE
DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
Checking the temperature of the
coolant and oils on the multi func-
tion display
When the temperatures of the engine coolant
and oil, and the oil pressure exceed the normal
range, the color of the meter on the multi
function display changes to red to warn the
driver. When engaging in high performance
driving, switch the display to the function meter
to display the temperature of the engine coolant
and oil, and the oil pressure. When the color of
the meter display changes to red, perform cool
down driving. When the values of the tempera-
ture and pressure return to the normal range, the
color of the meter display will turn back to white.
Warning temperature:
. Engine coolant temperature is 2308 F
(1108C) or higher:
If the engine coolant temperature increases
above 2308F (1108C) , the color of the meter
display on the multi function display changes
to red to warn of a possible overheat condition and engine output is reduced.
. Engine oil temperature is 2758F (1358C) or
higher:
If the engine oil temperature is higher than
2758F (1358C), the meter display changes
to red, maximum engine speed is automati-
cally limited to 4,000 rpm, and the transmis-
sion automatically changes from the
&M
position to the&Aposition.
. Transmission oil temperature is 2848 F
(1408C) or higher:
If the transmission oil temperature increases
to over 2848F (1408C) , the color of the
meter display changes to red. However, the
vehicle can continue to be driven until the
temperature reaches 2958F (1468C) . If the
oil temperature exceeds 2848 F (1408C)
while driving (the color of the meter dis-
played in red) , change both the transmission
oil and the differential oil after driving
because these fluids have deteriorated
because of the heat.
Cool down

the vehicle if coolant temperatures are extremely
high. Drive the vehicle at 37 to 50 MPH (60 to
80 km/h), in 5th or 6th gear for 2 to 3 miles (3 to
5 km) and then stop the engine.
Refueling precautions
WARNING
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire. The fuel tank
is full at the first automatic shutoff.
To maximize vehicle performance, the fuel tank is
located as low as possible to lower the vehicle
center of gravity. The tank is also divided into
two parts. This fuel tank design causes higher
pressures inside the tank than other vehicles so
fuel spillage is possible by trying to top off the
fuel tank after automatic shutoff.
The fuel tank pressure is higher when the vehicle
is hot, especially if the tank is more than half full.
If the cap is opened when the vehicle is hot, it
may cause fuel spray and there may be a hissing
noise. Open the cap slowly, releasing the
pressure from the tank gradually. Also, if the vehicle is refueled when the vehicle is hot, the
fuel pump may automatically shut off before the
tank is full. This does not indicate that there is a
malfunction. Refuel slowly or refuel after the
vehicle has cooled.
INSPECTION AND ADJUSTMENTS
BEFORE DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
Fluids
.
Check the engine, transmission, differential
and under vehicle surfaces for oil and
coolant leaks.
. Check the fluid levels and adjust as neces-
sary using the specified fluid as described
under the conditions listed in this section.
(
“Recommended fluids and mainte-
nance interval” page GTR-20 ) If you do
not drive under the conditions listed, refer to
the 2014 NISSAN Service and Maintenance
Guide.
. NISSAN recommends to adjust the engine
oil level
*1to be 0.39 in (10 mm) (1/8 gal
(0.5 liters))
*2below the H mark on the
engine oil dipstick. (
*3range is 1.18 in (30
mm)) Before checking the oil level, run the
engine until it reaches operating tempera-
ture and wait at least 5 minutes after turning
off the engine. Make sure the oil level always
remains above the L mark.
When the vehicle is delivered, the engine oil
is set to “H- 0.39 in (10 mm)” for optimal
high performance driving.
. Some amount of oil is consumed by your
engine under normal operating conditions,

distilled water mix is used.
Engine and powertrain
The information and specifications in this
section apply only when engaging in
performance driving.
.Check the engine, transmission, differential
and under the vehicle for oil and coolant
leaks.
. Inspect the areas surrounding of the cata-
lytic converter for heat deterioration.
. Always perform the transmission setting.
After that, adjust the clutch clearance so
that the clearance is less than the clearance
used for daily driving. Your GT-R certified
NISSAN dealer has the necessary informa-
tion and equipment to set the clutch
clearance to the correct specification. The
clearance used for daily driving increases
clutch heat generated during Performance
Driving. This leads to an increase in tem-
perature of the transmission oil. In addition, a
more direct shifting feel can be obtained by
reducing the clutch clearance for Perfor-
mance Driving. The clutch clearance should
be reset to the daily driving specification
after Performance Driving. See your GT-R
certified NISSAN dealer for information.
NOTICE
Failure to have the clutch properly
adjusted before performance driving
may cause the transmission oil tem-
perature to increase which may cause
transmission damage.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
Suspension and wheel alignment
The information and specifications in this
section apply only when engaging in
performance driving.
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
(
“Wheel alignment” page GTR-10)
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for high performance driv-
ing. Preventing toe-out:
Toe-out can cause uneven tire wear or
damage to areas inside the tires due to
high heat. Be sure to have the wheel
alignment toe-in setting checked and ad-
justed by your GT-R certified NISSAN
dealer before any performance driving on
closed circuit tracks. Obey all traffic laws
when on public roads.

the wheels. The tire may slip on the wheel if
the vehicle is driven in these conditions
before 48 hours have passed. If the tire slips
on the wheel, the wheel/tire assembly will be
out of balance and will require rebalancing.
Brakes
The information and specifications in this
section apply only when engaging in
performance driving.
.Check for the heat deterioration of the
brakes and parts around the brakes.
. It is recommended that you remove air from
the brake system after any of the following:
— When engaging in high performance
driving for the first time after purchasing
a new vehicle.
— After replacing the brake fluid.
— When engaging in high performance driving for a sustained period of time. It
is recommended that bleeding the brake
be performed when the brake calipers
are hot (about 2128F (1008C)) .
Brake pad:
NISSAN recommends adding an additional
cross spring to the front calipers before enga-
ging in performance driving. The additional
spring reduces brake pad movement resulting from cornering forces and will reduce the stroke
of the brake pedal. Contact a GT-R certified
NISSAN dealer to purchase the spring and
arrange installation. If a cross spring is added, a
clattering or squeaking sound may be heard on
rare occasions.
Brake pad break-in procedure:
NISSAN recommends that a special brake pad
break-in procedure be performed before enga-
ging in performance driving. Contact a GT-R
certified NISSAN dealer for details.
INSPECTION AND ADJUSTMENTS
AFTER DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
NOTICE
At the completion of performance driv-
ing, all fluid and other adjustments
should be returned to the normal fluid
specifications as shown in the “Main-
tenance and do-it-yourself” section of
this manual.

Check if there is no deformation on the
contact surface of the wheel nuts.
. Make sure the wheel nuts are tight.
(
“Wheels and tires” page 8-32)
. Make sure the drive shaft nuts are tight.
. Check wheel hub run out and that the wheel
rotates smoothly without any friction. Check
these with the tires removed whenever an inspection is performed with the vehicle
jacked up.
. Make sure the tire has not slipped on the
wheel causing the assembly to be out of
balance. The reference marks on the tire and
wheel should be aligned. If the reference
marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires reba-
lanced. Make sure the old reference marks
are erased and new reference marks are
applied to the wheel and tire. When instal-
ling new tires on the wheels, make sure new
reference marks are applied to the wheels
and tires. (

REFUELING PRECAUTIONS
WARNING
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire. The fuel tank
is full at the first automatic shutoff.
To maximize vehicle performance, the fuel tank is
located as low as possible to lower the vehicle
center of gravity. The tank is also divided into
two parts. This fuel tank design causes higher
pressures inside the tank than other vehicles so
fuel spillage is possible by trying to top off the
fuel tank after automatic shutoff.
The fuel tank pressure is higher when the vehicle
is hot, especially if the tank is more than half full.
If the cap is opened when the vehicle is hot, it
may cause fuel spray and there may be a hissing
noise. Open the cap slowly, releasing the
pressure from the tank gradually. Also, if the
vehicle is refueled when the vehicle is hot, the
fuel pump may automatically shut off before the
tank is full. This does not indicate that there is a
malfunction. Refuel slowly or refuel after the vehicle has cooled.
GASOLINE SMELL
The fuel temperature is higher when the vehicle
is hot. This may cause a gasoline smell from the
vehicle. This does not indicate that there is a
malfunction. The smell will go away when the
fuel temperature has cooled.
OUTSIDE TEMPERATURE DISPLAY
INDICATES HIGHER TEMPERATURE
Heat from the engine compartment, radiator and
intercoolers can affect the outside temperature
display. The outside temperature display may
indicate a higher than actual temperature while
driving or stopped. This is normal.
IDLE SPEED IS NOT STEADY
The idle speed may not be steady when the
engine compartment is extremely hot. This is
normal. The engine speed will be steady when
the engine cools down.
In this case, the Malfunction Indicator Light (MIL)
may come on. After a few driving trips, the MIL
should turn off. If the light remains on after a few
driving trips, have the vehicle inspected by a
GT-R certified NISSAN dealer.
ENGINE SPEED IS RESTRICTED
To help protect the engine, the maximum engine
speed is automatically controlled in the following
conditions:
.
Revving the engine with the shift lever in the
&Por&Nposition: The maximum engine
speed is 5,000 RPM
. Revving the engine when the engine oil is at
a low (below 328F(0 8C)) or extremely high
(over 2758 F (1358C)) temperature: The
maximum engine speed is 4,000 RPM (The
&Mposition will automatically change to the
&Aposition.)
ENGINE OUTPUT
High altitude
To protect the engine, engine output is con-
trolled so that it does not increase at altitudes
4,922 ft (1,500 meters) or higher.
Engine output according to the
coolant temperature
The engine output is controlled at a low level
when the engine coolant temperature is lower
than approximately 1588F (708C) or higher than
2308F (1108C). This is not a malfunction.
If the temperature is lower than approximately
GT-R SPECIFIC VEHICLE
CHARACTERISTICS

1588F (708C) , drive the vehicle until it reaches
normal operating temperature. If the temperature
is higher than 2308F (1108C), perform cool-
down driving procedure. (
“Cool down”
page GTR-13) When the temperature of the
engine coolant is between 1588F (708C) and
2308F (1108C) , the engine output returns to
normal.
DISTORTION OF REAR SPOILER
When the vehicle is parked in direct sunlight on
a hot day, the center of the rear spoiler may
become distorted. This is normal. When the
surface temperature of the rear spoiler is
reduced, the shape of the spoiler should return
to normal.
UNEVEN WEAR OF TIRES
The GT-R is equipped with high performance,
low profile, run-flat tires that are optimized for
performance and handling. The life of these tires
will be less than those of tires installed on a
typical vehicle, and you are likely to experience
uneven tire wear and tire noise regardless of the
type of tire used.
NOISES ARE HEARD WHILE DRIV-
ING
. The GT-R brake pads use material that
provides a high amount of braking power
even in high temperatures. This material can
cause an intermittent screeching noise just
before the vehicle comes to a stop when the
brakes are gently applied. The noise de-
creases as the brake pads wear. However,
the additional brake pad break-in or repla-
cing the cross spring may decrease the
noise. Contact a GT-R certified NISSAN
dealer.
. A screeching noise may be heard when the
brake pedal is depressed:
— When driving the vehicle for the first time
in the morning,
— After leaving the vehicle parked for extended periods of time, or
— When the vehicle is damp following rain showers or washing the vehicle.
These sounds are normal. The noise is
caused when the brake pads absorb moist-
ure, and the noise stops after the brake is
applied several times.
. A screeching noise may also be heard when
the brake pedal is depressed: — When repeatedly applying gentle brak-
ing, especially on a curve at a low speed,
or
— When the brake rotors have circular scores with the brake temperature high.
WARNING
Follow the instructions below when
parking the vehicle to help prevent the
brake rotor and brake pads from rust-
ing together. Failure to follow the
instructions could cause the rotor and
pads to rust together. If the rotor and
pads rust together, there may be a
popping noise and some vibration
when the vehicle is driven, a wheel
may not roll correctly, or the brake pads
could be damaged. If the pads are
damaged, this may reduce the effec-
tiveness of the brake system which
could cause a collision, serious perso-
nal injury or death.
. The GT-R uses brake pad materials that
have high metallic content. The brake pad
material helps maintain braking performance
in a wide range of weather and driving
conditions.
