Additional Notes
- The 1957-1958 Cadillac Series 60 cooling system carries a capacity of 18.8 liters, which is the largest figure across all model years listed in these specifications.
- From 1959-1963, the cooling system capacity settles at 18.2 liters, a modest reduction from the earlier 18.8-liter figure seen in 1957-1958.
- The 1959-1960 and 1961-1963 configurations share an identical 18.2-liter cooling system capacity, meaning no change was introduced between those two consecutive groupings.
- For 1964, the base cooling system capacity drops to 16.3 liters, the lowest value recorded across the entire 1957-1964 span covered in these specifications.
- The 1964 model year is the only one in these specifications to list a split capacity figure, where the presence of factory air conditioning raises the cooling system fill to 17.3 liters versus the base 16.3 liters.
- The 1.0-liter difference between the base and air-conditioned 1964 configurations reflects the additional coolant volume required to service the condenser or auxiliary heat exchanger associated with the air conditioning system.
- All four row entries carry a normal use condition, meaning none of the capacities listed are associated with a severe-duty or first-fill service distinction.
