Additional Notes
- The Wolseley 18/85, Six, ADO17 coolant specifications cover two distinct engine families across the 1967-1975 production span, with the 18/85 running from 1967-1972 and the Six from 1972-1975.
- On the 18/85, the cooling system capacity with a heater is listed at 5.2 liters, while the without-heater figure drops to 4.8 liters, a difference of 0.4 liters attributable to the additional fluid volume held within the heater matrix and its connecting hoses.
- The 0.4-liter difference between the heater and non-heater configurations on the 18/85 applies equally to both the manual and automatic transmission variants, as both share identical cooling system capacities across those two conditions.
- The Six and Six automatic each carry a cooling system capacity of 9.6 liters with heater, which is notably larger than the 5.2-liter heater-equipped figure recorded for the 18/85, reflecting the greater displacement and additional cylinder count of the six-cylinder engine.
- No without-heater capacity figure is listed for the Six or Six automatic, whereas the 18/85 specifications include both heater and non-heater values, making the Six entries single-figure specifications tied exclusively to the heater-equipped configuration.
- All four rows carry a normal use condition designation, meaning none of the capacity figures are associated with a severe-duty or first-change-only service distinction.
