2014 NISSAN GT-R check engine

Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Transmission
&Pmechanism: On a fairly
steep hill, check that your vehicle is held
securely with the shift lever in the
&Pposition
without applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, see a GT-R certified NISSAN dealer
immediately. Keep the floor mat away from the
pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the
parking brake applied. If the parking brake needs
to be adjusted, see a GT-R certified NISSAN
dealer. Seat belts:
Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and
in sufficient quantity when operating the heater
or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) . Battery*:
Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe condition require frequent checks of the
battery fluid level.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait at least 5 minutes for the oil to
drain back into the oil pan before checking the
oil.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes in the engine compartment,
immediately have the exhaust system inspected
by a GT-R certified NISSAN dealer.

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.

LOCATIONS

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
*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.
Maintenance and do-it-yourself8-13

.Keep the battery surface clean and dry.

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
