Not overly familiar w/vehicle, but I assume it's at the engine end of the upper radiator hose in a housing that is secured by 2 or 3 bolts. Drain about a gallon of coolant from radiator when engine is cool remove these bolts and observe hoe thermostat is mounted Clean both surfaces Install new gasket and thermostat Start engine --refill coolant slowly to prevent "airlock" and observe for leak. Run engine with heater on to normal operating temperature and top off radiator. Fiero engines have a thermostat that is easily removable from a "radiator" cap in the engine compartment. There's no unbolting or resealing necessary.

Asked in Thermostats, Pontiac Fiero, Grand Am GT
Where is the thermostat located on a 1985 Pontiac fiero gt?
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.
