Hi all, After a new timing belt and water pump last year I noticed occasional failure of the in car heating. Recently this is combined with high engine temperature - when the heating drops off, the temperature rapidly rises to the red but comes down to reasonable level of driven with low load (i.e. about 50mph and np on the flat. There's a useful YouTube suggesting this may be caused by air in the cooling system. Apparently this is a common fault with 2003 legacy caused by orientation of the stat. . My garage is stumped but I wondered if anyone else had come across this problem. Thanks Nick
