NISSAN 2014 GT R - Service & Maintenance Guide - Manual (Page 18)

To maximize vehicle performance, the coolant mixture ratio
should be a combination of 30% coolant/antifreeze and
70% demineralized or distilled water for maximum cooling
system performance regardless 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 Powertrain
* Check the engine, transmission, differential and under
the vehicle for oil and coolant leaks.
* Inspect the areas surrounding the catalytic converter for
heat deterioration.
* Always perform the transmission setting. After that,
adjust the clutch clearance so that the clearance is smaller
than the usual clearance. Large clutch clearance in-
creases clutch heat generation. This leads to an increase
in temperature of the transmission oil. In addition, a more
direct shifting feel can be obtained by adjusting the clear-
ance to be small. Perform the adjustment again after High
Performance Driving. See your GT-R certified NISSAN
dealer for information.
NOTICE: Failure to have the clutch properly ad-
justed before performance driving may cause the
transmission oil temperature 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 Alignment
* Check the steering and suspension system and other
links for loose and/or damaged parts.
* Measure and adjust the wheel alignment. Contact a GT-R
certified NISSAN dealer to adjust the wheel alignment to
the recommended setting for high performance driving.
Preventing toe-out:
Toe-out can cause uneven tire wear or damage to areas
inside the tires due to high heat. Be sure to have the wheel
alignment toe-in setting checked and adjusted by your
GT-R certified NISSAN dealer before any performance
driving on closed circuit tracks. Obey all traffic laws when
on public roads.
