Aux Drive Belt

[dan]

Trying to fit a new Drive Belt to a 2002 (52 Reg) 1.9 with Power Steering believe its a post September 2002 model (DW) i've got the old on off, mapped the new on out onto the cams etc but there's not enough slack to put it around the Cam Shaft pulley

Does anyone know where and how to take the tension off? (Drivers side wheel is off and cant see any adjustment points, cant find any adjuster nut under the bonnet (i'm banging my head against a wall right now:brickwall: so any help would be much appreciated)
