Cooling System: Description and Operation

COOLING SYSTEM FOR INVERTER, MG1 AND MG2

System Diagram






System Description
- An inverter cooling system that is independent from the engine cooling system has been provided to cool the inverter, MG1 and MG2.
- This inverter cooling system activates when the power supply status is switched to the READY ON state.
- A sub radiator, which is exclusively used for the inverter, MG1 and MG2, has been provided in front of the radiator and condenser assembly (for the engine cooling and A/C).









- The inverter 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 inverter cooling system additives are not necessary.

CAUTION: When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/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 inverter cooling system.
