Additional Notes
- The Cadillac Series 62/6200 cooling system capacity across the 1957-1964 model years spans a range from 16.3 liters to 18.8 liters, reflecting variation tied to specific model year groupings rather than a single fixed figure.
- The Series 62 for 1957-1958 carries the largest cooling system capacity in the lineup at 18.8 liters, a figure consistent with the demands of large-displacement V8 engines common in full-size American vehicles of that era.
- Both the Series 62/6200 for 1959-1960 and the Series 62 for 1961-1963 share an identical cooling system capacity of 18.2 liters, despite spanning four separate model years across two distinct type designations.
- The 1964 Series 62 introduces a split capacity specification, where the base cooling system holds 16.3 liters and the air conditioning-equipped variant requires 17.3 liters, a difference of one full liter attributed directly to the added thermal load of the air conditioning system.
- The 1964 air conditioning capacity figure of 17.3 liters represents a conditional specification, meaning the larger fill volume applies only when the vehicle is equipped with air conditioning, not as a universal service fill for all 1964 units.
- The 1964 model year marks a notable reduction from the 18.2-liter capacity seen in 1961-1963, with even the air conditioning variant at 17.3 liters falling below the prior years' figure, indicating a change in engine or cooling system architecture between those periods.
