      I always used the pink one called g12+ or g12++ in my S2..... filling, running idle and bleeding both screws... driving in rough circles a while, bleeding again in idle

              Flush it and do it properly with 100% G12

                No. It's turns into a horrible brown gunk!

                  I wouldn't do it. They are two different types of coolant, in short the G11 is high silicate non OAT, the G12 is OAT.
