Additional Notes

  • The Volvo FL-12 (EU) cooling system capacity is listed at 45 liters across all three engine variants — the FL 12-340, FL 12-380, and FL 12-420 — for the 1995-1998 model years.
  • A 45-liter coolant capacity is consistent with a heavy-duty commercial truck engine, where large displacement powertrains require substantial coolant volume to manage thermal load across the engine block, cylinder head, and ancillary circuits.
  • All three configurations share the D12A engine designation, and the uniform 45-liter figure across the 340, 380, and 420 power output variants indicates the cooling system architecture remains unchanged regardless of the power rating within the D12A family.
  • The capacity values listed apply under normal use conditions, meaning the 45-liter figure reflects standard operating service fills rather than a dry-fill or overhaul scenario, which would typically account for additional fluid retained in hoses, the heater circuit, and other ancillary passages.
