Gotcha, so where is the thermostat? How exactly do you disconnect it and ensure that all your AF is going into the block?

Yep, that's the tube I was wondering about. It has two smaller tubes coming off it heading towards the front of the engine (so the transmission as you say). I put my finger in there and it felt like fabric/porous so wondered what it was.
