Coolant capacity & service interval

The Audi 100, 43 (EU) coolant specifications cover a fluid type of coolant with a capacity range of 7 to 7.5 liters. The data includes three configurations for this model.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Use: Normal
  • Capacity 7,5 liter
100 1.6 (1976-1979)

Additional Notes

  • The Audi 100, 43 (EU) 1.6 carries a cooling system capacity of 7 liters, which is the smaller of the two capacity figures seen across the 1976-1979 lineup.
  • Both the 2.0 and the five-cylinder 5E variants share a cooling system capacity of 7.5 liters, a half-liter increase over the 1.6 figure.
  • The 1.6 and 2.0 engine variants cover the full 1976-1979 model year span, while the 5E entered the range later, with specifications beginning from 1977-1979.
  • All three configurations list coolant capacity under a normal use condition, meaning the 7 and 7.5 liter figures apply to standard operating environments rather than severe-duty cycles.
  • A cooling system capacity in the 7 to 7.5 liter range is consistent with a full system fill, accounting for the radiator, engine block passages, heater core circuit, and expansion reservoir volume typical of passenger car designs of the era.
