Remove the Air Intake Box so you can see in below... there is a pipe running right into the bell where the thermostat is housed. There is one bolt that you need to take remove (it is to the right, below the distributor, it goes into the engine block). Then there are the other 12 mm bolts on the bell of the thermostat housing to remove. After removing those the thermostat should be able to come right out. When replacing i would recommend getting a replacement thermostat with a jiggle pin...
