Additional Notes

  • The DAF 66 cooling system capacity is 4.8 liters across all listed configurations, covering the 1100, 1100 Marathon, and 1300 Marathon variants from 1972-1975.
  • A 4.8-liter cooling system capacity is a relatively modest figure, consistent with the small-displacement engines found in compact economy cars of the early 1970s.
  • The 66 1100 and 66 1100 Marathon share identical cooling system specifications, with both carrying a 4.8-liter capacity and a 12-month change interval under normal use conditions.
  • The 66 1300 Marathon, introduced in 1973, also carries the same 4.8-liter capacity and 12-month interval as the 1100-based variants, despite the larger engine displacement.
  • A 12-month coolant change interval under normal use conditions was a common service standard of the era, reflecting the antifreeze and corrosion inhibitor technology available at the time rather than extended-life formulations seen in later decades.
  • The 66 1100 Marathon ran from 1972-1973, while the 66 1300 Marathon covered 1973-1975, with both sharing the same cooling system fill volume of 4.8 liters throughout their respective production periods.
