engine coolant NISSAN GT-R 2022 Service Manual

NOTICE
If the gauge indicates engine coolant
temperature near the hot (H) end of
the normal range, reduce vehicle
speed to decrease temperature. If
gauge is over the normal range, stop
the vehicle as soon as safely possi-
ble. If the engine is overheated,
continued operation of the vehicle
may seriously damage the engine.
(
“If your vehicle overheats” page
6-8)
FUEL GAUGEThe gauge indicates the approximate
fuel level in the tank.
The gauge may move slightly during
braking, turning, acceleration, or going
up or down hills.
The gauge needle returns to E (Empty)
after the ignition switch is pushed to the
LOCK position.
Refill the fuel tank before the gauge
registers “E” (Empty).
The low fuel warning will be indicated on
the vehicle information display when the
fuel tank is getting low. Refuel as soon as
it is convenient, preferably before the gauge reaches “E”. There will be a small
reserve of fuel in the tank when the fuel
gauge needle reaches “E”. (
“Low fuel
warning” page 2-43)
The
indicates that the fuel-filler door
is located on the passenger’s side of the
vehicle. (
“Fuel-filler door” page 3-24)
NOTE:
If the vehicle runs out of fuel, the
Malfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
After a few driving trips, the
light
should turn off. If the light remains on
after a few driving trips, it is recom-
mended you have the vehicle inspected
by a GT-R certified NISSAN dealer.

4,000 rpm when the engine oil or
coolant temperature is low or higher
than normal.
. If the ignition switch is pushed
before the shift lever is moved to
the
position, the ignition switch
will not change to the OFF position.
If this occurs, the SHIFT
warning
display appears on the vehicle in-
formation display. When stopping
the engine, be sure to move the shift
lever to the
position and then
push the ignition switch. Failure to
do so may result in discharge of the
battery. (“Shift “P” warning”
page 2-46)
. If the shift lever was in the
position when the engine was
stopped, then be sure to move the
shift lever to the
position before
starting the engine the next time. If the engine is started with the shift
lever in the
position, then it may
not be possible to drive the vehicle
even when the shift lever is moved
to the
position. If this
occurs, the SHIFTwarning appears
on the vehicle information display.

“Shift “P” warning” page 2-46)
CAUTION
If the engine was stopped soon
when the engine is hot, the cooling
fan may operate for approximately 2
minutes after the engine was
stopped to cool the components in
the engine compartment. When the
cooling fan is operating, be sure that
hands or other items do not get
caught in it.
DUAL CLUTCH TRANSMISSIONThe GT-R dual clutch transmission is a
newly-developed system that uses an
electronically controlled multiple-disc

The GT-R dual clutch transmission was
developed specifically to maximize vehi-
cle performance and driving enjoyment.
The GT-R transmission components were
designed using different engineering
standards than typical passenger car
transmissions. Because of this, the GT-R
has different operating characteristics,
and various rattle noises may be heard
during some driving conditions because

DRIVING THE VEHICLE

NOTICE
.When the temperature of the
engine coolant and transmission
oil is high or low, the function
cannot be used. The temperature
range in which the R mode start
function can be used:
— Engine coolant: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. If the R mode start function is
used 4 times consecutively, the
function may be disabled and
cannot be turned on to protect
the vehicle system. While the function is disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) When the warning
light turns off, the function can be
used again.
. The performance of start may
vary depending on the amount
of wheel spin ,or increase and
decrease of the engine output in
response to the outside tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. For safety reasons, VDC control
may activate automatically when
driving on a slippery road surface,
such as a wet road, in order to
apply the brakes or limit the
engine output.
. Frequent use of the R mode start
function increases the load on
the powertrain related parts such
as the clutch and transmission
compared to normal driving. In
particular, the clutch will wear out

R MODE START FUNCTION

Do not use the cruise control when
driving under the following condi-
tions. Doing so could cause a loss of
vehicle control and result in an acci-
dent.
.When it is not possible to keep
the vehicle at a set speed.
. In heavy traffic or in traffic that
varies in speed.
. On winding or hilly roads.
. On slippery roads (rain, snow, ice,
etc.).
. In very windy areas.
NOTE:
. When the SAVE mode is selected
with the transmission setup switch,
the acceleration and deceleration
can be controlled smoothly. When
the SAVE mode is selected, the
maximum setting speed is lower
than the one in the normal mode. When the vehicle approaches a gen-
tle uphill, there may be a slight delay
as the vehicle returns to the preset
speed. However, the vehicle will
gradually accelerate and return to
the preset speed.
PRECAUTIONS ON CRUISE CON-
TROL.
If the cruise control system malfunc-
tions, it will cancel automatically. The
SET indicator will blink and the cruise
control system warning will appear to
warn the driver. (
“Cruise control
system warning” page 2-43)
. If the engine coolant temperature
becomes excessively high, the cruise
control system will be canceled auto-
matically.
. If the SET indicator blinks, turn the
cruise control main switch off and it is
recommended you contact a GT-R

wheels will lose even more trac-
tion.
. Allow more stopping distance
under these conditions. Braking
should be started sooner than on
dry pavement.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare
ice). These may appear on an
otherwise clear road in shaded
areas. If a patch of ice is seen
ahead, brake before reaching it.
Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous ex-
haust gases under your vehicle.
Keep snow clear of the exhaust
pipe and from around your vehi-
cle.
NOTE:
When driving on snow, select the SAVE
mode with the setup switch. By select-
ing the SAVE mode, the engine output is
controlled appropriately for snow or slippery road surfaces. This enables
the vehicle to start or accelerate
smoothly.
ENGINE BLOCK HEATER (if so
equipped)Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.To use the engine block heater1. Turn the engine off.
2. Plug the engine block heater cord into
a grounded 3-wire, 3-pronged exten-
sion cord.
3. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
4. The engine block heater must be plugged in for at least 2 - 4 hours,
depending on outside temperatures,
to properly warm the engine coolant.
Use an appropriate timer to turn the
engine block heater on.
5. Before starting the engine, unplug and properly store the cord to keep it
away from moving parts.

.
NOTE:
Do not keep the starter motor en-
gaged for more than 10 seconds. If
the engine does not start right away,
push the ignition switch to the OFF
position and wait 10 seconds before
trying again.
7. After starting your engine, carefully disconnect the negative cable and
then the positive cable (

?“Removing the cowl top cover”
page 8-5) Do not attempt to start the engine by
pushing.
NOTICE
Your NISSAN cannot be push-started
or tow-started. Attempting to do so
may cause transmission damage.
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 radia-
tor filler cap and the coolant
reservoir cap while the engine is
still hot. When the cap is removed,
pressurized hot water will spurt
out, possibly causing serious in-
jury.
. 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
position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the temperature
control to maximum hot and fan

position.
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection whenever you work on your ve-
hicle.
. 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
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing 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
engine oil and coolant. Impro-
perly 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
component while the ignition
switch is in the ON position.
. Never leave the engine or trans-
mission related component har-
nesses disconnected while the
ignition switch is in the ON posi-
tion.

MAINTENANCE PRECAUTIONS

by pulling it towards
the front of the vehicle. 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 pro-
tection. The anti-freeze solution contains
rust and corrosion inhibitors. Additional
engine cooling system additives are not
necessary.

, open the
reservoir cap (pressure type)and add
coolant up to between the MAX
and
MIN
level. If the reservoir is empty, open
the radiator filler cap
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. This vehicle contains Genuine NISSAN
Long Life Antifreeze/Coolant (blue). The
life expectancy 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 “9. Maintenance and sche-
dules” section of this manual for more
details.
If the cooling system frequently re-
quires coolant, it is recommended you
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 mid-
point, the amount of coolant circulating
may be insufficient for maximum vehicle
performance, possibly causing engine
overheating or other trouble.
For the coolant level and mixture ratio
when engaging in performance driving,
see
“Coolant level and mixture ratio”
page GTR-15.
Except for NISMO models:
If it is difficult to determine the midpoint
between MAX and MIN, remove the cool-
ant reservoir cap and look inside through
the opening to check that the coolant
level is above the divider
between the
top half and bottom half of the pressur- ized 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
coolant reservoir cap. Doing so
will cause substandard cooling
performance 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 possi-
ble.CHANGING ENGINE COOLANTIf major cooling system repairs are re-
quired, it is recommended you 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 re-
duced heater performance and engine
overheating.
