Additional Notes
- The Hudson Super Six (1946-1947) carries the largest cooling system capacity across all listed configurations, reaching 18.7 liters when equipped with a heater, compared to the base capacity of 17.8 liters for the same engine without one.
- The heater-equipped capacity figure of 18.7 liters applies exclusively to the Super Six (1946-1947) and does not appear in any other row, meaning the additional 0.9 liters accounts for the coolant volume held within the heater circuit itself.
- The Super Eight saw a reduction in cooling system capacity between model year groups, dropping from 17 liters in the 1946-1947 configuration to 16 liters in the 1948-1951 configuration.
- The Super Six retained a consistent base capacity of 17.8 liters across both the 1946-1947 and 1948-1951 groups, while the Super Eight did not maintain the same consistency across those same periods.
- For the 1946-1947 model years, the Super Eight and Super Six share a base capacity figure of 17 liters and 17.8 liters respectively, placing the six-cylinder engine in a slightly larger cooling system than the eight-cylinder counterpart.
- All four configurations share a check interval of 1,000 miles under normal use conditions, which reflects a relatively frequent monitoring schedule typical of mid-century automotive cooling systems.
