Additional Notes
- The Peugeot 504 petrol variants, including the base 504, 504GL, and 504Ti, all share a cooling system capacity of 7.8 liters under normal use conditions.
- The 504 Diesel carries a notably larger cooling system capacity of 10 liters under normal use conditions, which is approximately 28% more than the petrol variants.
- The increased coolant capacity in the 504 Diesel reflects the greater thermal load diesel engines generate, requiring a larger volume of coolant to maintain operating temperatures.
- All four configurations share the same normal use condition designation, meaning the listed capacities apply to standard operating environments rather than severe or extreme service conditions.
- The 504GL and 504Ti trims, both introduced in 1971, carry the same 7.8-liter cooling system capacity as the original 1968 base model, indicating no change in cooling system volume across those trim levels.
- A 7.8-liter figure represents a full cooling system service fill, accounting for the radiator, engine block passages, heater core, and connecting hoses as a combined volume.
