Additional Notes
- The Ferrari 400's cooling system capacity is listed as a range of 15-20 liters rather than a fixed value, which reflects the variability typical of a full system drain and refill on a large-displacement grand touring engine, where air pockets and residual fluid in hoses and the heater core can affect the total volume accepted during service.
- Both the 400 GT covering 1976-1979 and the 400 GTi covering 1979-1985 share an identical capacity range of 15-20 liters, indicating no meaningful change to the cooling system volume between the two variants despite the GTi's introduction of fuel injection.
- The change interval for both configurations is set at 12 months under normal use conditions, a time-based rather than mileage-based interval, which is consistent with the degradation rate of glycol-based coolants that break down chemically over time regardless of distance driven.
