STANDARD 3 CORE RADIATOR, We sell a ton of the super 2-core and 4-core radiators, but that may be more cooling power than you need. If you have a standard Mini and live in a cool climate this 3-core may be more than adequate, and definitely better than your old rusted, clogged one! Picture is for reference use only, the fan is not included. From 1980 all factory fitted radiators were to the old Cooper S spec of 3 rows of cores and 16 gills per inch to cope with the hotter running engines. However the basic problem is the lack of water capacity and all the late minis have 5/8" bore heater hoses as opposed to the old 1/2" bore.
