Additional Notes

  • The Honda ZR-V Hybrid RZ4 (EU) carries a 2.0 E:HEV PF engine, and the main cooling system holds 7.4 liters at initial fill. A service fill, which reflects the volume exchanged during a routine coolant change rather than a full system drain and refill, comes to 5.8 liters.
  • The 1.6-liter difference between the initial fill and service fill capacities indicates that a portion of coolant remains trapped in the system during a standard service drain, a common characteristic of sealed or pressurized cooling circuits.
  • Under normal use conditions, the main cooling system interval is set at 100,000 km or 60 months, whichever comes first.
  • Under initial service conditions, the main cooling system interval extends to 200,000 km or 120 months, reflecting a longer-life coolant formulation used from the factory fill.
  • The electric motor and drive system carry a separate cooling circuit with a capacity ranging from 1.0 to 1.8 liters, a variable range that likely accounts for differences in system configuration or residual fluid retention during a drain.
  • The electric motor cooling circuit follows the same interval structure as the main system: 100,000 km or 60 months under normal use conditions, and 200,000 km or 120 months under initial service conditions.
