hello guys. today i wanted to change my thermostat for my FD. so i start unbolting stuff but the housing wont come loose. i've unbolted a total of 3 bolts on the housing. i've got pictures here. if theres others to unbolt where are they? it seemed like an easy job but i think i have to remove the whole air filter unit to access the bolts near the air pump

 

first pic, is an air pump bolt. the third bolt for the housing is on that same side, lower down.

 

Yup there are 3 10mm bolts for the housing, you haven't unscrewed the left hand side one.
