How do I change my Auxillary belt for my Peugeot 406?

For anyone else wondering on a 307 you have to loosen 2 13mm nuts that look as if they should allow a tensioner wheel assembly to slide up (and away from the belt). But you ALSO need to loosen off a smaller bolt that rises straight up into the tensioner wheel assembly. If you feel around you will quickly locate it. Awkward but do-able for a beginner!
