PAS belt, undo the 3 retaining bolts on the pulley on the PAS pump. That belt is now off, Alternator belt - slacken off the 2 bolts that hold the alternator so you can push down on the alternator and that belt is now loose enough to take off
Refitting is the reversal of removal, but the PAS belt is a little bit of a cow to get back on. But it will go on
Its pretty straight forward really
