Additional Notes
- The Jaguar S-Type (EU) cooling system capacity is 12.5 liters across all four configurations covered in the 1963-1968 production span.
- Both the 3.4 and 3.8 engine variants share an identical 12.5-liter cooling system capacity, indicating no displacement-related difference in coolant volume between the two engines.
- A 12.5-liter cooling system capacity is relatively substantial for a passenger car of the 1960s, reflecting the thermal demands of the inline-six engines used in the S-Type.
- All four configurations carry a normal use condition designation, meaning the 12.5-liter capacity figure applies to standard operating conditions rather than a severe-duty or special-case scenario.
- The 3.4 specification is split across two sub-periods, 1963-1965 and 1965-1968, yet the cooling system capacity remains unchanged at 12.5 liters across both periods.
- The same continuity applies to the 3.8 variant, where the 1963-1965 and 1965-1968 sub-periods both carry the 12.5-liter figure, suggesting no mid-cycle revision to the cooling system volume.
