Additional Notes

  • The Humber Super Snipe Mark IV (1952-1958) carries a cooling system capacity of 18.18 liters, a notably larger figure than all subsequent series and consistent with the older, larger-displacement inline-six engine fitted to that generation.
  • From the Series I onward (1958-1967), the cooling system capacity drops to 14.2 liters across all five series, reflecting the adoption of the newer 2.6-liter overhead-valve six-cylinder engine introduced with the Series I.
  • The 3.97-liter difference in coolant capacity between the Mark IV and the Series I represents a meaningful reduction in system volume, which generally corresponds to a smaller or more efficiently packaged engine bay cooling circuit.
  • A check interval of 400 km applies uniformly across all configurations from 1952-1967, indicating a very short inspection cycle by modern standards and typical of mid-twentieth century maintenance schedules that assumed more frequent owner attention.
  • The coolant change interval of 9,600 km is consistent across every series from 1952-1967, regardless of the capacity difference between the Mark IV and the later Series I through V variants.
  • The 9,600 km change interval, common in vehicles of this era, reflects the limitations of early antifreeze and corrosion inhibitor formulations, which degraded more rapidly than modern long-life coolants and required more frequent replacement to maintain adequate freeze and boil-over protection.
  • All specifications across the 1952-1967 production span are listed under normal use conditions, meaning the stated check and change intervals are not adjusted for severe operating environments such as extreme temperatures or heavy loads.
