I need a quick DIY advice for getting to the thermostat. that bottom 10MM bolt is a bbb???tch to get to. I Am just trying to replace the thermostat.

Any procedures recommended? Remove the coupleing hose first? etc. I can see that bolt but have no room to work. Can't get to it from below as far as I can see. Can't get a ratchet on it from the top.

Can't find anything on the forum.
