Additional Notes

  • The Volvo 66 (EU) cooling system capacity is 4.8 liters across all four trim variants covered in the specifications, namely the L, DL, GL, and GLS Combi.
  • A 4.8-liter cooling system capacity is relatively modest, consistent with the compact engine displacement typical of small European vehicles from the mid-1970s.
  • The 66 GLS Combi carries the same 4.8-liter coolant capacity as the other trims, despite entering the specifications at a later starting year of 1977 compared to the 1975 start year of the L, DL, and GL variants.
  • The coolant check interval is set at 10,000 km under normal use conditions for all four trims, meaning the interval applies to standard operating circumstances rather than demanding or severe driving environments.
  • The 10,000 km check interval represents a periodic inspection point rather than a full coolant replacement, as the specification uses the term "check" rather than a drain-and-fill or flush designation.
