radiator NISSAN GT-R 2014 R35 Owners Manual

EXTERIOR PARTS (spoiler, etc.)
Do not modify exterior parts.
The GT-R was developed using a special wind
tunnel to help make sure the vehicle is
aerodynamically balanced. Additionally, the wind
tunnel was used to help make sure cool air flows
to the brakes, radiator and other components.
Additions of non-genuine GT-R specific acces-
sory exterior parts can change the air flow over
and around the body. This can affect vehicle
balance and cooling of various systems.
For example, if the front bumper is modified,
there is a possibility that brake cooling perfor-
mance may be reduced due to the decrease of
the air flow to the brake system.
Use only GT-R special specification parts.
Front bumper
The shape of the bumper helps pull air into the
engine compartment through the front wheel
housing to cool the radiator and brakes. Instal-
ling an aftermarket bumper may affect the air
flow in the engine compartment and decrease
the brake and engine cooling performance. An
aftermarket bumper may also change vehicle
balance by reducing front down force.
Rear spoiler
Installing an aftermarket rear spoiler may change
the down force balance between front and rear
of the vehicle. This can affect the handling
characteristics of the vehicle and affect the
operation of the ABS and VDC systems.
NOTICE
Modifications to exterior parts may
affect engine and transmission cooling
performance which can increase the
temperature in the engine compart-
ment. This can affect the operation or
damage parts located in the engine
compartment.
DRY CARBON FIBER PARTS (if so
equipped)
The dry carbon fiber parts are made using the
same composite method used for race cars. The
dry carbon fiber parts has a special coating to
enhance the feel of the material.
NOTICE
.Do not use chemical agents (for
example: wax, coating agent, com-
pound agent, etc.) on the dry carbon
fiber parts because they can da-
mage the material. When the carbon
fiber parts become dirty, dilute one
cap of mild detergent with a bucket
of water and use that mixture to
clean the carbon fiber parts.
. The dry carbon fiber parts may turn
yellow due to age deterioration
because of the characteristics of
the material. Storing the vehicle
outside in direct sunlight for ex-
tended periods of time may cause
discoloration and deterioration.
NISSAN recommends that you do
not store the vehicle in direct sun-
light to protect the rear spoiler.
NOTE:
The surfaces of the dry carbon fiber parts
are lightly coated like a race car so that
you can feel the proper texture of real
carbon, which may feel rough. This is
normal.

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

ENGINE COMPARTMENT

CAUTION
.Do not insert hands, clothing, tools
or other items into the engine
compartment while the engine is
running.
. Do not touch the exhaust system
parts, radiator or other hot parts
until the engine and the parts have
cooled.
NOTICE
Do not open the hood while the wiper
arms are lifted away from the wind-
shield. The hood and wipers will be
damaged.CLOSING THE HOOD
1. While supporting the hood, store the stay to
the original position.
2. Slowly lower the hood. When it is at a height of 1 ft (30 cm) or higher, drop the hood and
make sure that both sides of the hood
securely lock in place.
WARNING
. Make sure the hood is completely
closed and latched before driving.
Failure to do so could cause the
hood to open and result in an accident.
. Be sure to check that the hood is
securely closed before driving. If
both sides of the hood are not
locked in place, the hood may open
during driving, possibly causing an
accident.
CAUTION
When closing the hood, lower it slowly
so that hands or other items do not get
caught.
NOTE:
Because the hood of this vehicle requires
more force to close than that for other
vehicles, the hood will be difficult to close
if you lower it all the way and then attempt
to press it closed. Be sure to drop the hood
from a height of approximately 1 ft (30 cm)
and be sure that both sides securely lock
in place.
Pre-driving checks and adjustments3-19

6-8In case of emergency
WARNING
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radiator
filler cap and the coolant reservoir
cap while the engine is still hot.
When the cap is removed, pressur-
ized hot water will spurt out, possi-
bly causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect unusual
noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
the
&Pposition.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the temperature control to
maximum hot and fan control to high speed. 3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radiator
before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no steam
or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the drive belts are missing or loose, or the
cooling fan does not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine
cooling fan can start at any time.
7. When the coolant temperature gauge goes down to the midpoint, stop the engine and
wait until the gauge goes down further to
“C” (cold).
8. After the engine cools down, check the coolant level in the reservoir tank. Add
coolant to the reservoir, if necessary, after
opening the coolant reservoir cap with a
heavy cloth covering it. (
“Engine cool-
ing system” page 8-10)
9. Have your vehicle repaired at the nearest GT-R certified NISSAN dealer.
IF YOUR VEHICLE OVERHEATS

air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected
immediately.
Power steering fluid level* and lines:Check
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the end
of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. (
“Underbody” page 7-3)
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.
When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself or
damage to the vehicle. The following are general
precautions which should 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. .
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.

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze
and coolant protection. The anti-freeze solution
contains rust and corrosion inhibitors. Additional
engine cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator or cool-
ant reservoir cap when the engine is
hot. Wait until the engine and
radiator cool down. Serious burns
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 −348 F
(−378C) . 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 −348 F
(−378C) . 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.
ENGINE COOLING SYSTEM

CHECKING ENGINE COOLANT LE-
VEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
*2, open the reservoir cap
(pressure type)
*Band add coolant up to
between the MAX and MIN level
*3. If the
reservoir is empty, open the radiator filler cap
*A
and 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 up to between the MAX and MIN
level
*3.
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, have it checked by a GT-R certified
NISSAN dealer.
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.
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 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
