Additional Notes
- The Honda Civic XI FL4/FL5 (EU) 2.0 E:HEV PF cooling system carries an initial fill capacity of 7.3-7.4 liters, which represents the total volume required when filling a fully drained or newly assembled system, compared to the 5.6-liter service fill used during routine coolant changes.
- The 2.0 Type-R PF cooling system lists an overhaul capacity of 8.2-8.3 liters, a notably higher figure than the E:HEV PF initial fill, reflecting the greater total system volume associated with the high-performance turbocharged engine and its associated cooling hardware.
- The Type-R PF service fill stands at 6.7 liters, meaning a standard coolant drain and refill procedure recovers less than the full overhaul volume, which is a normal characteristic of cooling systems where some residual fluid remains in passages and the heater circuit.
- Under normal use conditions, the Type-R PF cooling system follows a change interval of 100,000 km or 60 months, while the first change only condition extends that interval to 200,000 km or 120 months, indicating the factory-fill coolant is formulated for significantly longer initial service life.
- The E:HEV PF main cooling system also carries a 100,000 km or 60-month change interval under normal use, but the initial service condition extends the first change to 200,000 km or 120 months, mirroring the same first-fill longevity pattern seen on the Type-R PF.
- A separate cooling circuit dedicated to the electric motor and system on the 2.0 E:HEV PF holds a capacity of 1-1.75 liters, a much smaller volume than the main engine cooling system, consistent with the compact thermal management loop typical of hybrid drive unit cooling.
- The electric motor cooling circuit on the E:HEV PF shares the same 200,000 km or 120-month change interval across both normal and initial service conditions, with no shorter interval applied under normal use, unlike the main engine cooling system.
- Both the main and electric motor cooling systems on the E:HEV PF share a check interval of 20,000 km or 12 months, keeping inspection frequency consistent regardless of the differing change intervals between the two circuits.
