The standard removal technique is to tap the bung with a hammer to loosen it and try to remove it with a single hex spanner or socket, if this does not work try to use a screwdriver in the centre at the same time as using the spanner.
It is common for the bung to become stuck if it is done up too tight, if this is the case chisel the bung from the side. The bung will break in half and the tension will be released from the thread and the remainder will unscrew with your hand. If you do this you will obviously need to buy a new bung, I suggest you buy a brass one from a radiator shop.
