thats thrown me,unless i'm mistaken ,the astra cambox is a seperate unit and so the only tools required that are not standard are a timing belt locking kit.you'll see what i mean when you remove the cam box.i would recomend renewing the waterpump when you do this as adjusting the belt is sooo much easier.they dont cost that much.
