Coolant: Service and Repair
Anti-Freeze Coolant Mixture Ratio
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 anti-freeze coolant or equivalent with the proper mixture ratio of
50% anti-freeze and 50% demineralized water/distilled water.
Other types of coolant solutions may damage your cooling system.
