Additional Notes
- The Bristol 411 cooling system holds 16.5 liters across both the 1969-1973 and 1973-1976 configurations, a capacity typical of large-displacement engines where substantial coolant volume is needed to manage heat across a wide operating range.
- The 16.5-liter figure listed for both configurations represents a full cooling system capacity, meaning the total volume of coolant the system holds when filled from empty, as opposed to a partial drain-and-refill quantity.
- Both the 411 (1969-1973) and the 411/7612122 (1973-1976) share an identical 16.5-liter cooling system capacity under normal use conditions, indicating no change in cooling system volume between the two configurations despite the variant designation introduced in the later production period.
