Additional Notes
- The Wolseley Hornet carries a cooling system capacity of 3.55 liters across all four configurations spanning 1961-1969, which is consistent with a small-displacement engine typical of compact British vehicles from that era.
- A 3.55-liter coolant capacity falls on the lower end of the spectrum for passenger cars, reflecting the compact engine bay and modest engine size shared across the MK I, MK II, and MK III variants.
- The MK I (1961-1963), MK II (1963-1967), and MK III (1967-1969) all share an identical 3.55-liter capacity, indicating no cooling system enlargement occurred across the generational updates during the production run.
- The MK III automatic (1967-1969) also holds 3.55 liters, meaning the addition of an automatic transmission did not alter the cooling system capacity relative to the standard MK III.
- A coolant check interval of 4800 km applies uniformly across all configurations under normal use conditions, placing routine inspection on a relatively frequent cycle by modern standards, which was common practice for vehicles of the 1960s.
- The 4800 km check interval represents a service inspection point rather than a full coolant replacement, meaning the system is monitored for level and condition at that mileage rather than drained and refilled each time.
- The consistency of both the 3.55-liter capacity and the 4800 km check interval across the MK I through MK III, including the automatic variant, suggests the cooling architecture remained unchanged throughout the 1961-1969 period covered by the specifications.
