All this radiator talk has made me feel a bit guilty and that aside the inside top of the header tank is covered in a sort of white scum. So I feel a coolant change and a header tank washout is due.
Could any of you good people give me any pointers as to the best way of going about the draining and refilling of a Duratec 2 litre. I can't see a drain plug for the block for instance, nor can I see any bleed taps for excluding air when refilling.
