There is a little plastic gromet cover over the tensionar bolt. Remove it then you have access to loosen the tensioner.
The bolt inthere varies between makes and models..... some cars required an allen wrench, while others will take a 22mm (I think) socket.
Place whatever the appropriate size socket, and turn clockwise (you will be physically moving the tensioner and taken tension off the belt so you can remove it.
