2021 NISSAN GT-R coolant reservoir

.
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
PUSH STARTING IF YOUR VEHICLE OVERHEATS

Check the coolant level in the pressurized
coolant reservoir. Adjust the level so that
the fluid is between the MAX and MIN
markings. For the coolant, use genuine
NISSAN Long Life coolant or equivalent.
(On delivery of new vehicle, the reservoir
is filled to the MIN level. Be sure to
replenish approximately 3/8 US quart
(0.3 to 0.4 liter) of coolant.)
NOTICE
Do not overfill the coolant. This may
increase the pressure in the cooling
system and cause coolant leaks.
To maximize vehicle performance, the
coolant mixture ratio should be a combi-
nation of 30% coolant antifreeze and 70%
demineralized or distilled water for max-
imum cooling system performance re-
gardless of ambient temperatures.
If ambient temperatures are anticipated
below 5°F (−15°C), make sure a proper
mixture ratio of 50% antifreeze and 50%
demineralized or distilled water mix is
used.Engine and powertrainThe information and specifications in
this section apply only when engaging in performance driving.
.
Check the engine, transmission, differ-
ential and under the vehicle for oil and
coolant leaks.
. Inspect the areas surrounding of the
catalytic converter for heat deteriora-
tion.
. 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 information
and equipment to set the clutch
clearance to the correct specification.
The clearance used for daily driving
increases clutch heat generated dur-
ing Performance Driving. This leads to
an increase in temperature of the
transmission oil. In addition, a more
direct shifting feel can be obtained by
reducing the clutch clearance for
Performance Driving. The clutch clear-
ance should be reset to the daily
driving specification after Perfor-
mance Driving. It is recommended
you see a 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 alignmentThe 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 align-
ment. (

tact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the
recommended setting for high perfor-

, 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.
