Toyota IQ 1.0 Changing the two auxiliary belts

Changing the two belts on my girlfriends little toyota IQ car.
This is the 2010 model. I think the uses other auto tensioners on the later models, from 2012 and on wards.
The worst is the cramped space to work in, if it was not for that this job would been far less annoying.
TLDR: Cramped and annoying plastic.
