Hello! I’m a fellow pre-facelift C63 AMG owner. Two questions. 1). Isn’t the recommended coolant specification supposed to be MB 325.0 which should be blue in colour, not yellow like the one you added? I’m also hoping you added pre-diluted coolant and not concentrate. 2). According to the user manual, you are supposed to check the marker/tab in the coolant expansion tank and not based on the moisture on the coolant expansion tank cover. Feel free to correct me if I’m wrong, but you may want to revisit the owner manual.
