Additional Notes

  • The Mercedes-Benz 300 SE, W112 (EU) carries a coolant system capacity of 16.8 liters, which represents a full cooling system fill volume — the total amount of coolant fluid the entire system holds, including the engine block, cylinder head passages, radiator, and hoses.
  • A 16.8-liter cooling system capacity is notably large, consistent with the 300 SE W112's inline-six engine architecture, where longer coolant passages through a larger displacement engine block require a greater total fluid volume to maintain thermal regulation.
  • The single capacity figure of 16.8 liters applies under normal use conditions, meaning standard operating environments without the elevated thermal demands associated with severe-duty classifications such as towing, extreme ambient temperatures, or prolonged low-speed operation.
