Hi,
remove the front bumper (some tricky screws, somewhat more complicated than on a usual Typ 44, unfortunately), remove the head lamps, the lock carrier (guess it's called so) and finally you can move the AC radiator downwards and remove the coolant radiator.
There may be easier ways to accomplish a removement of the whole front, but I'm not aware of one. Just take care that the AC circuit remains closed!
You said the campbelt has already been changed - do you mean the engine timing belt or just the flat belt for the auxillery aggregates? If the engine timing belt is still the first one, you should change it asap, as Tim also proposed.
