ENGINE COOLING SYSTEM The engine cooling system is filled at the factory with a high-quality, year-round, antifreeze coolant solution. The anti-freeze solution contains rust and corrosion inhibitors, therefore additional engine cooling system additives are not necessary. CAUTION When adding or replacing coolant, be sure to use only an ethelene glycol antifreeze with the proper mixture ratio of 50% Genuine Nissan Anti-freeze coolant or equivalent and 50% demineralized or distilled water. The use of other types of coolant solutions may damage the engine cooling system. Outside temperature down to °C −35 °F −30 Genuine Nissan Anti-freeze coolant or equivalent 50% WARNING ● Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator. ● The radiator is equipped with a pressure type radiator cap. To prevent engine damage, use only a genuine NISSAN radiator cap. WDI0144 CHECKING ENGINE COOLANT LEVEL Check the coolant level in the reservoir when the engine is cold. If the coolant level is below MIN, add coolant up to the MAX level. If the reservoir is empty, 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. If the cooling system frequently requires coolant, have it checked by an authorized NISSAN dealer. Maintenance and do-it-yourself Demineralized or distilled water 50% 8-9
