ADDITIONAL MAINTENANCE ITEMS, CONTINUED

NISSAN recommends that the brakes should be
bled before engaging in performance driving and
when replacing the brake fluid. It is recommend-
ed that bleeding the brakes be performed when
the brake calipers are hot [about 212°F (100°C)]

●

Check around the engine, transmission, differen-

tial and under the vehicle for oil and coolant leaks.

●

Before engaging in performance driving, the

clutch clearance may need to be adjusted. See
your GT-R certified NISSAN dealer for information.
NOTICE: Failure to have the clutches properly
adjusted before performance driving may cause
the transmission oil temperature to increase
which may cause transmission damage.

●

Check the steering and suspension system

and other links for loose and/or damaged parts
before and after driving.

REPLENISHING COOLANT

The information and specifications below apply only
when engaging in performance driving.
Check the coolant level in the pressurized
coolant reservoir tank. Adjust the level so that
the fluid is between the MAX and MIN mark-
ings. For the coolant, use genuine NISSAN
Blue Long Life Antifreeze/Coolant. (On delivery
of a new vehicle, the reservoir is filled up to the
MIN level. Be sure to replenish approximately
0.3 to 0.4 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

INSPECTION AND ADJUSTMENTS OF
TIRES, SUSPENSION, CLUTCHES
AND BRAKES

The information and specifications below apply only
when engaging in performance driving.

●

Measure and adjust (if needed) the wheel

alignment.

●

Check tire wear.

●

Check the tire pressure and adjust the pres-

sure as necessary when the tires are cold.
Refer to GT-R Owner’s Manual.

●

Make sure the tire valve stem cap is

installed and that the valve stem is tight.

●

Make sure the wheel nuts are tight.

●

Make sure the drive shaft nuts are tight.

●

Secure road wheel balance weights with

aluminum tape or equivalent.

●

Make sure the tire has not slipped on the wheel

causing the assembly to be out of balance. The ref-
erence 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
rebalanced. Make sure the old reference marks are
erased and new reference marks are applied to the
wheel and tire. When installing new tires on the
wheels, make sure new reference marks are
applied to the wheels and tires.

●

Check for the heat deterioration of the brakes

and parts around the brakes.

cause coolant leaks.

COOLANT MIXTURE RATIO
The information and specifications below apply only
when engaging in performance driving. For maxi-
mum cooling system performance, the coolant mix-
ture ratio should be a combination of 30%
antifreeze and 70% demineralized or distilled water.

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 is used.
Do not add coolant over the MAX level. This
may cause coolant leaks because the pressure
in the cooling system may become too high and
a hose may become disconnected.
To maximize vehicle performance, the coolant
mixture ratio should be a combination of 30%
antifreeze and 70% demineralized or distilled
water for maximum cooling system performance
regardless of ambient temperatures.

COOL DOWN
The information and specifications below apply only
when engaging in performance driving.
Cool down the vehicle to help extend the life of 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.
