CHECKING ENGINE COOLANT LEVEL Check the coolant level in the reservoir when the engine is cold. If the coolant level is below 2 , open the reservoir cap the MIN level * B (pressure type) * and add coolant up to 3 . If the between the MAX and MIN level * A reservoir is empty, open the radiator filler cap * 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 3 . level * This vehicle contains Genuine NISSAN Long Life Antifreeze/Coolant (blue). The life expectancy 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 Maintenance 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 maximum 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 3 that the coolant level is above the divider * 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 nonpressure type cap. Do not switch the radiator filler cap and the coolant reservoir cap. Doing so will cause substandard cooling performance 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. .
