patience , and a 13 MM wrench , you gotta get your arms in there deep , that lower bolt does not need to come all the way off , the thermostat housing has a slot at the bottom for easier access , loosen it about 3.4 of the way and you can get the housing out , experience says a premium thermostat will give you grief trying to reinstall , get a regular duty thermostat .reverse procedure.
