Moin, the new moose has the color according to G12 as coolant in it, in my other moose I have the original G11 from Volvo. The colors also differ red and blue. I would like to release the “wrong” coolant completely and put the G11 on it, but have read once that the two should not mix with each other. How can I get the complete “wrong” coolant out of the cooling circuit? Gruß Flo
