Whats the best way yo do it, the smaller overflow coolant tank i need to use with my fmic might be a bit too small and is overflowing at some point while being driven on, so a bit of coolant has been used up. Can i just top up the radiator and header tank? Its always been full or ive gotten it done in the garage so not something i have looked into before. Also when engine is cold sure there be anything in the overflow tank or thats only used while your driving of expansion etc.
