Removing belt to change alternator

[wali110]

I decided to change the alternator myself but am having problems getting the belt off, the videos online of other cars make it seem like a piece of cake but it just doesn't seem to work.

I drive a vectra c 2.2 petrol and the alternator sits right in the front of the car.

Can anyone help me? I ca upload pictures if need be.

thanx guys

The belt has just snapped on my 2.2 . You get access by taking off the front wheel and the the wheel arch insert....
