Additional Notes

  • The Ford Cortina Mk II (EU) cooling system capacity holds at 6.2 liters across the 1300, 1500, 1600, 1600 GT, and 1600E variants, a figure that reflects the total volume of the sealed cooling circuit including the radiator, engine block passages, and heater core.
  • The Cortina 1500 carried the 6.2-liter coolant capacity only during its 1966-1967 production window, after which the 1600 series took over the same displacement class with the same capacity figure from 1967 onward.
  • The Cortina Lotus specifies a slightly lower cooling system capacity of 6.0 liters, compared to the 6.2 liters shared by all other variants. The Lotus variant used a twin-cam engine developed by Lotus Engineering, which differed substantially in cylinder head design from the Kent and Crossflow units fitted to the other Mk II models, and the minor capacity difference reflects the distinct architecture of that engine's cooling passages.
  • All six variants list coolant capacity under normal use conditions, meaning the figures apply to standard operating environments rather than severe-duty or high-temperature service scenarios.
  • The 6.2-liter figure for the 1600, 1600 GT, and 1600E represents a service fill capacity, indicating the volume required when refilling a drained but otherwise intact cooling system, as opposed to a dry-fill figure that would account for a fully disassembled engine block.
