Additional Notes
- The Honda Prelude 1600 cooling system holds 7 liters of coolant, which represents the total system capacity for a full drain and refill of the cooling circuit.
- Under normal use conditions, the Prelude 1600 calls for a coolant change at 48,000 km or 24 months, whichever comes first, meaning both a distance threshold and a time threshold govern the service interval.
- The 24-month time limit on the coolant change interval reflects the chemical degradation of antifreeze and corrosion inhibitors over time, independent of mileage accumulated.
