Additional Notes
- The Honda Insight ZE2 cooling system carries two distinct capacity figures per configuration: a dry fill value and a service fill value. The dry fill represents the total system volume when completely empty, such as after a full overhaul or component replacement, while the service fill reflects the smaller volume needed during a routine coolant exchange where residual fluid remains in the system.
- For the 2009-2011 Insight Hybrid, the cooling system dry fill capacity is 5.04 liters, and the service fill capacity is 4.55 liters. The difference of approximately 0.49 liters between the two figures reflects the residual coolant that stays trapped in the system during a standard drain and refill procedure.
- The 2011-2014 Insight Hybrid carries a dry fill capacity of 4.9 liters and a service fill capacity of 4.4 liters, placing both figures slightly below those of the earlier configuration. The gap between dry and service fill remains consistent at approximately 0.5 liters.
- Both configurations share a flexible service interval governed by the on-board maintenance system rather than a fixed mileage or time schedule. The on-board maintenance system monitors driving conditions and vehicle data to determine when service is due, adjusting the interval accordingly.
- The 2011 model year appears in both row configurations, indicating a mid-cycle specification change occurred during that year. A 2011 vehicle may correspond to either the 5.04-liter or the 4.9-liter dry fill specification depending on which production variant applies.
