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 a Genuine NISSAN / INFINITY anti-freeze coolant or equivalent with the proper
mixture.
Other types of coolant solutions may damage the engine cooling system.
