Additional Notes
- The Honda Accord XI 1.5T, from 2022, has a cooling system service fill capacity of 6.1 liters, which represents the amount of coolant needed when draining and refilling the system during routine maintenance rather than a full overhaul.
- The Accord XI 2.0 Hybrid cooling system carries a service fill capacity of 5.7 liters, which is 0.4 liters less than the 1.5T engine's cooling system, reflecting the different thermal management demands of the hybrid powertrain.
- The 2.0 Hybrid configuration adds a separate inverter cooling circuit with a service fill capacity ranging from 1.1 to 1.8 liters, a variable range that accounts for the difficulty of fully purging air from smaller auxiliary cooling loops during a service fill procedure.
- All three configurations listed for 2022 specify a flexible service interval governed by the on-board maintenance system, meaning the vehicle's monitoring system determines coolant change intervals based on actual operating conditions rather than a fixed mileage or time schedule.
