The engine cooling system is filled at the factory with a high-quality, year-round, anti-freeze coolant solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system additives are not necessary.
■ CAUTION ■
When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/ Coolant (blue) or equivalent with the proper mixture ratio.

- The coolant mixture ratio should be a combination of 30% antifreeze and 70% demineralized or distilled water for maximum cooling system performance.
- If ambient temperatures are anticipated to be below 5°F (−15°C), make sure a proper mixture ratio of 50% antifreeze and 50% demineralized or distilled water mix is used.
- To maximize vehicle performance, the coolant mixture ratio should be a combination of 30% antifreeze and 70% demineralized or distilled water for maximum cooling system performance regardless of ambient temperatures.
