Peskyjones the auxilliary belt and the cambelt are two different things. You will be releasing the aux. belt tensioner and locking it at which point you can remove the aux. belt. Might aswell change it when removed as they are cheap. Further down the line you actually should remove the tensioner aswell makes access much easier.
There is a fair bit of underneath work, but with correctly positioned axle stands its perfectly safe.
Wear long sleeves aswell... my forearms were cut to shreds on the front bonnet slam panel!
