MINI Convertible F57 Coolant Expansion Tank Malaysia
The F57 shares the same plastic expansion tank design concerns as the Cooper hatch. Convertible owners should be alert to slow coolant loss without a visible leak, which is often the first sign of a hairline crack. Because engine bay access in the F57 is similar to the F56 hatch, replacement is straightforward. Do this proactively when the coolant is due for a change.
