Additional Notes

  • All six Austin A40 variants covered in these specifications share an identical cooling system capacity of 7.3 liters, indicating a common engine cooling architecture across the entire A40 range from 1947 through 1956.
  • A 7.3-liter coolant capacity falls within the typical range for small four-cylinder engines of the late 1940s and early 1950s, reflecting the relatively modest displacement of the A-series and related powerplants used in the A40 lineup.
  • The uniform 8,000 km coolant change interval applies to all listed variants under normal use conditions, a relatively short interval by modern standards, consistent with the coolant technology and engine metallurgy common to vehicles of that era.
  • The A40 Cambridge GS5 carries the same 7.3-liter capacity and 8,000 km interval as earlier variants such as the Devon and Dorset, despite representing a later generation of the A40 line produced from 1954-1956.
  • The A40 Dorset, produced from 1947-1950, and the A40 Devon, produced from 1947-1952, share not only the same capacity and interval but also overlap in production years, reflecting a period when Austin offered both body styles concurrently.
  • The A40 Sports, covering 1947-1953, retains the same 7.3-liter cooling system specification as the more conventional saloon and estate variants, suggesting no cooling system enlargement was made to accommodate the sportier application.
