Additional Notes
- The Morris Mini cooling system capacity across all three listed configurations — the MINI Cooper, MINI Cooper S, and MINI Minor MK I — is 3 liters, indicating a small-displacement engine with a correspondingly compact cooling circuit.
- The MINI Minor MK I carries the widest production span of the three configurations, covering 1959-1967, while the MINI Cooper covers 1961-1963 and the MINI Cooper S covers 1963-1964.
- A 3-liter coolant capacity is notably low by general automotive standards, reflecting the Morris Mini's famously space-efficient and lightweight engineering rather than a high-volume engine bay.
- All three configurations share an identical 3-liter capacity under normal use conditions, meaning no variation in cooling system volume exists between the standard Minor MK I and the higher-performance Cooper and Cooper S variants within the years specified.
