Additional Notes
- All six variants of the Audi F103 range — the 60 (40 kW), 60 (48 kW) Export, 72, 75, 80, and Super 90 — share an identical cooling system capacity of 7.5 liters, indicating a common engine bay architecture across the entire model family spanning 1965-1972.
- A 7.5-liter cooling system capacity is a total system fill figure, meaning it accounts for the radiator, engine block water jackets, heater core, and all connecting hoses taken together rather than the radiator alone.
- The 60 (48 kW) Export variant carries the same 7.5-liter cooling system capacity as the standard 60 (40 kW), despite the higher power output, suggesting the two share the same physical cooling circuit dimensions.
- The Super 90, which ran from 1966-1972 and represented the top-output variant of the F103 range, also holds 7.5 liters of coolant, consistent with the rest of the lineup rather than requiring an enlarged cooling system for its higher performance specification.
- All capacity figures are listed under normal use conditions, which in coolant service contexts typically refers to standard ambient temperature operation as opposed to extreme heat or cold environments.
- The 72 variant covered the earliest production window in the specifications, running from 1965-1969, while the 75 entered the range from 1969-1972, with both sharing the same 7.5-liter cooling system fill despite representing different displacement or output levels within the F103 lineup.
