This is a very simple procedure. Your upper radiator hose goes into the thermostat housing. To disconnect this hose without being sloppy, you could drain the coolant from the radiator's drain plugs first. But you could also just roll a pan under the car and disconnect the upper radiator hose. Only a quart or so of coolant will come out before it stops.
Then there are two bolts holding you thermostat housing in place. Remove those and then you'll be able to pull you thermostat right out.
Before replacing with the new one, make sure your old gasket material is removed because that will cause a leak.
And you might want to use a skinny bead of RTV with the new gasket to make sure it doesn't leak.
If I've helped you, please vote for me as I depend on this to pay my bills. Thanx, Ernest.
