Morris Mini

Coolant capacity & service interval

The Morris Mini coolant specifications cover a capacity of 3 liters. The data includes 3 different configurations for this model.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
MINI Cooper S (1963-1964)
  • Use: Normal
  • Capacity 3 liter
MINI Cooper (1961-1963)
  • Use: Normal
  • Capacity 3 liter
MINI Minor MK I (1959-1967)
  • Use: Normal
  • Capacity 3 liter

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.
