Additional Notes
- The Innocenti A40 and A40S share an identical coolant capacity of 5 liters, applying equally to both the 1959-1961 and 1962-1967 variants of the cooling system.
- A 5-liter coolant capacity places both configurations in the range typical of small-displacement engines from the era, where compact cooling circuits were standard practice.
- The check interval is set at 1,000 km under normal use conditions for both the A40 and A40S, reflecting a relatively short inspection cycle by modern standards.
- A 1,000 km check interval does not necessarily indicate a full fluid change at that frequency; in period service practice, such intervals were commonly associated with visual inspection and top-up procedures rather than complete drains.
- The normal use condition tied to the 1,000 km check interval applies uniformly across both the 1959-1961 and 1962-1967 model spans, with no differentiation between the two variants in either capacity or interval.
