very easy job to do.

ill give you the most common location first. follow the upper radiator hose, where it meets the engine, if you see two or three bolts on the thing the radiator hose connects to it is the thermostat housing, simply unbolt them and remove the housing and the thermostat. if you dont see that then follow the upper radiator hose to where it meets the engine near the tranny, it will be located in a housing there.
