Additional Notes
- The Bristol 409 cooling system holds 18.5 liters of coolant, which is a relatively large capacity for a passenger car and reflects the demands of the engine's thermal management requirements.
- The 18.5-liter figure represents a full cooling system fill, meaning the total volume of the entire circuit including the radiator, engine block passages, and hoses rather than a partial or top-up quantity.
- The capacity specification for the Bristol 409 (1965-1967) is listed under normal use conditions, meaning the 18.5-liter figure applies to standard operating environments rather than severe or high-stress service scenarios.
