Additional Notes

  • The Volvo P1800 (EU) cooling system capacity splits into two distinct values across the model range: 9 liters and 8,6 liters, depending on the variant and model year.
  • The P1800 (1961-1963) carries a 9-liter cooling system capacity, which matches the figure seen in the 1800S (1963-1968), indicating a shared cooling system architecture across those earlier years.
  • The 1800S spans two separate specification entries. From 1963-1968, the cooling system capacity is listed at 9 liters, while from 1968-1969 the figure drops to 8,6 liters, reflecting a mid-production change within the same model designation.
  • The 8,6-liter capacity applies to three variants: the 1800S (1968-1969), the 1800E (1969-1972), and the 1800ES (1971-1973), covering the later portion of the overall production span.
  • A cooling system capacity of 8,6 liters represents a total system fill volume, meaning the figure accounts for the radiator, engine block passages, heater core, and connecting hoses taken together as a single circuit.
  • All five specification rows are listed under normal use conditions, meaning the capacity values stated apply to standard operating environments rather than any severe-duty or high-load service classification.
  • The 1800ES (1971-1973) shares the identical 8,6-liter cooling system capacity with the 1800E despite being a distinct body style, the ES being a shooting brake variant of the coupe.
