Additional Notes

  • The DKW - Auto Union Junior / F11 / F12 cooling system capacity is uniform at 7.25 liters across all listed variants, spanning the Junior (1959-1962), Junior de Luxe (1961-1963), F11 (1963-1965), F12 29 kW (1963-1965), F12 33 kW (1965), and F12 Roadster (1964).
  • A 7.25-liter cooling system capacity is a moderately sized figure for small European passenger cars of the early 1960s, reflecting the full volume of coolant held within the engine block, cylinder head passages, radiator, and connecting hoses.
  • All six variants carry a normal use condition designation, meaning the 7.25-liter capacity figure applies to standard operating environments rather than severe-duty or high-temperature service conditions.
  • The F12 Roadster, produced only in 1964, shares the same 7.25-liter cooling system capacity as the closed-body F12 variants, indicating no cooling system modification was made for the open-top body style.
  • The two F12 power outputs, 29 kW and 33 kW, differ in engine tune but both carry the same 7.25-liter cooling system capacity, showing that the increased output of the 33 kW variant did not require a larger coolant volume.
  • The Junior and Junior de Luxe share the same 7.25-liter figure as the later F11 and F12 models, reflecting a consistent cooling system architecture across the generational progression of the range from 1959 through 1965.
