Before you buy or service: Cooling systems may be pressurized and hybrid vehicles can have multiple circuits. Follow the manufacturer procedure and never open a hot pressurized system.
How these references affect your decision

Production-date changes affect both cooling circuits

For HE12 e-POWER, Nissan separately documents engine and inverter coolant systems, and the published values change from July 2018. Both production date and circuit matter.

Never combine engine and inverter quantities or treat them as instructions to open high-voltage cooling hardware.
