Additional Notes

  • The Austin Seven AD015 850 carries a coolant capacity of 3 liters, which represents the total cooling system volume including the radiator, engine block passages, and hoses.
  • The 3-liter figure applies under normal use conditions, meaning standard operating environments without the added thermal stress associated with severe-duty classifications such as towing or extreme temperature exposure.
  • A cooling system capacity of 3 liters is relatively modest, consistent with the small-displacement 850cc engine architecture found in the Seven AD015, where a compact water jacket and radiator core are sufficient for the engine's heat rejection requirements.
