Additional Notes

  • The Morris Cowley 1500 Saloon, Series III carries a coolant system capacity of 8 liters, which is consistent with a full cooling system fill covering the radiator, engine block passages, and heater circuit.
  • The 8-liter figure applies under normal use conditions, meaning standard operating environments without the added thermal demands associated with severe-duty classifications.
  • A capacity at this level in a mid-1950s saloon reflects the relatively large water-jacketed inline engines typical of the era, where coolant volume played a direct role in managing heat across longer engine blocks.
