Additional Notes
- All five Hillman Imp variants listed — the Californian, Mk I, Mk II, Sport, and Super — share a uniform steering box capacity of 0.3 liter, indicating no variation in steering system volume across the model range covered by these specifications.
- A steering box, as opposed to a rack-and-pinion assembly, is a recirculating-ball or worm-and-sector unit that holds a relatively small fluid volume, and the 0.3 liter figure across all Imp variants is consistent with that type of compact mechanical housing.
- The Imp Mk I (1963-1965) carries a check interval of 8000 km under normal use conditions, meaning the steering box fluid level was to be inspected at that mileage point rather than replaced.
- The Imp Sport (1966-1976) specifies a change interval of 8000 km under normal use conditions, which calls for a full fluid replacement at that interval rather than a level check alone.
- The distinction between the Mk I check interval and the Sport change interval is notable given that both are set at 8000 km — the same numerical threshold applies to two different service actions depending on the variant.
- The Imp Californian (1967-1970), Mk II (1965-1973), and Super (1965-1976) list only a capacity figure with no associated service interval, meaning no check or change mileage is recorded in the specifications for those variants.
