11.5. Inverter cooling system
Never remove the radiator or coolant reservoir cap when the engine is hot. Wait until the engine cools down. Serious burns could be caused by high pressure fluid escaping from the radiator or coolant reservoir.
The coolant reservoir is equipped with a pressure type coolant reservoir cap. To prevent engine and inverter damage, use only a genuine NISSAN coolant reservoir cap.
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 cooling system additives are not necessary.
Never use any additives in the coolant such as radiator sealer in the cooling system. This may cause damage to the inverter.
When adding or replacing coolant, be sure to use only Genuine NISSAN Engine Coolant or equivalent in its quality with the proper mixture ratio. Examples of the mixture ratio of coolant and water are shown in the following tables:
Outside temperature down to | Coolant (concentrated) | Demineralised or distilled water | |
|---|---|---|---|
°C | °F | ||
−15 | 5 | 30% | 70% |
−35 | −30 | 50% | 50% |
The use of other types of coolant solutions may damage the inverter cooling system.
The inverter reservoir is equipped with a pressure cap. To prevent engine damage, use only a Genuine NISSAN inverter reservoir cap or its equivalent when replacement is required.
