There is a large cap in the engine compartment that looks somewhat like a radiator cap. Let your engine cool and make sure the coolant is NOT under pressure. Turn the cap counterclockwise till it stops, then just like a radiator cap press down on it and turn it 1/4 turn more. Take off the cap and you will find the thermostat right under it. Grab the "handle" with a pliers, give it a turn to break the seal and pull it out. Make sure your fiero is full of radiator fluid before you replace the thermostat. If there is no fluid under the cap when you opened it, your trouble is with a lack of fluid, not a bad thermostat. There is a special fill procedure when refilling a fiero with coolant.
