Coolant level and mixture ratio The information and specifications in this section apply only when engaging in performance driving. 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. (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.) . distilled water mix is used. Engine and powertrain 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. Inspect the areas surrounding of the catalytic converter for heat deterioration. Before engaging in performance driving, appropriate clutch adjustment must be performed by your GT-R certified NISSAN dealer. . . Adjust the power steering fluid level to the R 5 mark * on the power steering dipstick 6 when the fluid temperature is hot or * when the fluid temperature is cold. Fluid temperature: Hot: 122 to 1768F (50 to 808C): between 1 and * 5 * 3 Cold: 32 to 868F (0 to 308C): between * 6 and * 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 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 58F (−158C), make sure a proper mixture ratio of 50% antifreeze and 50% demineralized or NOTICE Failure to have the clutch properly adjusted 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). GT-R Overview GTR-15
