I would guess to bleed out the air in the system when you fill it after loosing fluid or after changing or flushing the system.

To replace a thermostat on a 2000 Ford F-250 V10, drain the radiator. Locate the thermostat on the top hose assembly and remove the screw. Replace the thermostat and refill the radiator.

Follow the upper radiator hose to the engine. It is clamped onto the thermostat cover. There should be a coolant bleed screw just above it. 3.1L engine.

Follow the TOP radiator hose to the engine block Remove the hose from the engine block. Thermostat should pop out. Some screw in, most pop out.

Not sure what year you have but on my 1984 its on top of the engine. Under the dome at the end of the radiator hose. There are 2 bolts that have to be removed in order to get to the thermostat. On a 1998 model, follow the top radiator hose to the engine. The hose attaches to an aluminum elbow with a brass slotted screw on top (the slotted screw is loosened to let air out of the cooling system). Remove the two bolts to take off the aluminum elbow and there will be your thermostat.
