• Cooling system service needs on Mini Cooper and Mini Cooper Countryman models

Installation Notes and Tips

Compatible With 2007-2013 Mini Cooper, N/A; 2011-2013 Mini Cooper Countryman, N/A. Some 2010-2012 Mini Cooper and 2011-2012 Mini Cooper Countryman applications require updated thermostat harness adapter 12517646145, and 2011 Mini Cooper applications also note this adapter requirement. Verify the existing cooling system layout and connector style before installation. Proper coolant refill and bleeding procedures are important after thermostat housing replacement to help prevent air pockets and temperature control issues.
