MINI MINI Convertible, F57 (USA)

Additional Notes

• The MINI Convertible F57 Cooper (100 kW) carries a cooling system capacity of 4.9–5.7 liters across both the 2015-2017 and 2017-2019 model periods. The range rather than a fixed value reflects normal variation between a drain-and-refill service fill and a full system overhaul, where residual coolant in hoses and the heater core affects the total volume retained.
• The Cooper S (141 kW) and John Cooper Works (170 kW) variants share a larger cooling system capacity of 5.8–6.1 liters. The higher output of both engines generates more heat, and the larger capacity range corresponds to a more substantial cooling circuit needed to manage thermal load at elevated power levels.
• The gap between the Cooper's 4.9–5.7 liter range and the Cooper S and John Cooper Works' 5.8–6.1 liter range reflects a meaningful difference in cooling circuit size tied directly to engine output. The 100 kW Cooper sits noticeably below the two higher-output variants in total system volume.
• All six configurations across the 2015-2019 model span are rated under normal use conditions. No severe-use interval or capacity distinction appears for any of the three engine variants, meaning the listed capacities apply uniformly without adjustment for demanding operating environments.
• The Cooper S (141 kW) and John Cooper Works (170 kW) share identical capacity figures of 5.8–6.1 liters despite a 29 kW difference in output between the two. A shared cooling circuit architecture between the two higher-output variants accounts for the matching specification.
• Capacity values are expressed as ranges rather than single figures across all six rows. In cooling system service, a range typically accounts for air pockets that may remain in the system after a refill, with the upper figure representing a fully bled and topped-off system.
