To change the thermostat on a 1987 Toyota Supra, begin by draining the coolant from the radiator. Next, remove the thermostat housing by unbolting it and disconnecting any hoses attached to it. Take out the old thermostat, clean the mounting surface, and install the new thermostat with the correct orientation (usually with the spring side facing the engine). Finally, reassemble the housing, reconnect the hoses, refill the coolant, and check for leaks.
