The engine cooling system is filled at the factory with a pre-diluted mixture of 50% genuine NISSAN long-life antifreeze/coolant (blue) and 50% water to provide year-round freezing protection. The antifreeze solution contains rust and corrosion inhibitors. It is not necessary to add any additives to the cooling system.

WARNING

  • Never remove the radiator cap or coolant reservoir cap while the engine is hot.
Wait until the engine and radiator have cooled. Hot coolant under high pressure may escape from the radiator and cause serious burns. Read the precautions in the "If the Engine Overheats" section of the "In Case of Emergency" chapter of this manual.
  • The radiator is equipped with a pressure-rated cap. To avoid engine damage, use only a genuine NISSAN radiator cap.

    • WARNING

    • Never use cooling system additives such as radiator sealant stop-leak products. Additives can clog the cooling system and cause damage to the engine, transaxle, or cooling system.
    • When adding or replacing antifreeze/coolant, be sure to use only genuine NISSAN long-life antifreeze/coolant (blue) or an equivalent product. Genuine NISSAN long-life antifreeze/coolant (blue) is pre-diluted to provide freezing protection to -37 C (-34 F). If additional freezing protection is required due to the extreme temperatures where the vehicle is operated, add genuine NISSAN long-life antifreeze/coolant concentrate following the directions on the container. If you use an equivalent product to NISSAN long-life antifreeze/coolant (blue), follow the antifreeze manufacturer's directions to maintain minimum freezing protection to -37 C (-34 F). Using coolant types other than genuine NISSAN long-life antifreeze/coolant (blue) or an equivalent product may damage the engine cooling system.
    • The service life of genuine coolant is 168,000 km (105,000 miles) or seven years. If you mix a coolant type other than genuine NISSAN long-life antifreeze/coolant (blue), including NISSAN long-life antifreeze/coolant (green), or use non-distilled water, the service life of the genuine coolant will be reduced.
