Ill give you a quick idea.
Remove all the plastic parts to get access. Including the secondary belt plastic cover. If you can get in there without removing the battery and box, that would be good.
basically, when you have enough access, use a size 13 spanner on the secondary tensioner to detension the belt. It is then a bit of a fiddle to get the old one out, and equal fiddle to get the new one in. Slip it over the bottom of the PAS pump first, then the tensioner then the CAM wheel. I found it easier for finger access this way.
Then pop all the plastic back on. Hope this helps.
