CHECKING ENGINE COOLANT LEVEL Check the coolant level in the reservoir when the engine is cold. If the coolant level is below 2 the MIN level * , open the reservoir cap B (pressure type) * and add coolant up to the 1 MAX level * . If the reservoir is empty, open the A 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 the MAX level 1 *. 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. . Never remove the radiator filler cap and the coolant reservoir cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator and reservoir. Avoid direct skin contact with used coolant. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible. Keep coolant out of reach of children and pets. . . . CHANGING ENGINE COOLANT If major cooling system repairs are required, contact a GT-R certified NISSAN dealer. The service procedures can be found in the appropriate NISSAN Service Manual. Improper servicing can result in reduced heater performance and engine overheating. Engine coolant must be disposed of properly. Check your local regulations. WARNING . To avoid the danger of being scalded, never change the coolant when the engine is hot. Maintenance and do-it-yourself 8-11
