The coolant in my SL1 is thick and dark. I've done a bunch of research on the internet and they mention that the Dexcool antifreeze should be changed regularly. How can I tell the difference between this and oil in the coolant? If it is the coolant, can it be flushed or do I need a new radiator?
have the same problem?
