MINI Countryman F60 Coolant Expansion Tank Malaysia
The F60's plastic expansion tank is susceptible to cracking, particularly on older units. Signs of a failing tank: the coolant level drops gradually without any visible external leak, or a sweet smell in the cabin from evaporating coolant. The Countryman's larger engine bay provides easier access than the Cooper for this replacement. Change coolant and tank together as a set for best results.
