Additional Notes

  • The Hillman Avenger cooling system capacity is listed at 7.33 liters across all four variants covered in the 1973-1976 model years, which represents a full system fill volume rather than a partial top-up figure.
  • A cooling system capacity of 7.33 liters is a moderate volume for small-displacement engines of the era, consistent with the total fill needed when draining and refilling the entire system including the radiator, hoses, and engine block passages.
  • The 1300 and 1300 TC variants share an identical 7.33-liter cooling system capacity, meaning the twin-carburettor TC specification did not alter the coolant volume requirement relative to the standard 1300.
  • The 1600 and 1600 TC variants also carry the same 7.33-liter figure, indicating the larger displacement engine shares the same cooling circuit volume as the 1300-series engines across the 1973-1976 range.
  • All four configurations carry a normal use condition designation, which in cooling system service contexts refers to standard operating environments without the additional thermal stress associated with severe-duty classifications such as towing or extreme temperature exposure.
