Additional Notes
- Both the 3.5 V6 (2005-2008) and the 3.7 V6 (2008-2012) share identical cooling system capacities, with a dry fill of 8.6 liters and a service fill of 6 liters.
- The dry fill figure of 8.6 liters represents the total volume of the cooling system when completely empty, as encountered during a full overhaul or major component replacement.
- The service fill of 6 liters reflects the amount of coolant needed during a routine drain-and-refill, where residual fluid remains in the engine block and heater core passages.
- The gap between the 8.6-liter dry fill and the 6-liter service fill indicates that approximately 2.6 liters of coolant is retained within the system even after a standard drain procedure.
- Under normal use conditions, the Honda Legend KB cooling system carries a change interval of 100,000 km or 60 months, whichever comes first, for both engine variants.
- The initial service interval for both the 3.5 V6 and the 3.7 V6 is extended to 200,000 km or 120 months, reflecting the longer service life of the factory-fill coolant used at the time of manufacture.
- The initial service interval of 120 months is exactly double the normal 60-month interval, meaning the first coolant change is scheduled at a significantly later point than all subsequent changes.
