Since I fitted the fmic and had to drain a bit of coolant out to clock Turbo, the aftermarket aluminium coolant overflow bottle keeps spitting out small amounts of coolant when driving. . I topped up the header tank and let the air bubble out, then too up from the Rad cap and added a bit to the overflow bottle. Does this mean there is still air in the system and I need to do a full drain or possibly something else causing this? Never done a full flush before myself so not sure how to do it.
