i realise the pic below is of a turbo engine, but i have noticed that it has a fan on the front of the radiator. having a little look around i have noticed that most astra's coupes and hatches have a fan on the front and an offset fan on the back regardless of engine size. mine only has the one on the back. is my fan missing? its a 2004 1.8 coupe i was wondering if its possible to get another fan for it?
