GTR-14 GT-R Overview
Coolant mixture ratio
The information and specifications in this
section apply only when engaging in
performance driving.
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.
If ambient temperatures are anticipated below
5
8F (−158C), make sure a proper mixture ratio of
50% antifreeze and 50% demineralized or
distilled water mix is used.
Inspection and adjustments of tires,
suspension, clutch and brakes
The information and specifications in this
section apply only when engaging in
performance driving.
. Check the engine, transmission, differential
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 clutch properly
adjusted before performance driving
may cause the transmission oil tem-
perature 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.
. Measure and adjust the wheel alignment.
( “Wheel alignment” page GTR-9)
. Check tire wear and cracking.
. Check the tire pressure and adjust the
pressure as necessary when the tires are
cold. (
“Wheels and tires” page 8-31)
*The chart above indicates an example of the
change in tire pressure (air) when measured and
adjusted with tire pressure at 77
8F (258C),
according to the change in outside air tempera-
ture of the modified tire inner pressure.
The tire pressure changes depending on the
outside temperature or altitude. Check the tire
pressure regularly and when the climate condi-
tions change.
