erinle8, it is most easily seen from under the car. Look up just behind the radiator (between the fans and the engine block) near the center of the car (maybe just a little to the driver's side for you). You should see a rubber and metal tube working its way up there with a black "football" shaped piece in the middle of this line. That is the thermostat. If you go up another 4", you will see a large plastic tee that the thermostat mounts to. There are 3 bolts on it, 120 degrees from each other. The bolts should be pretty easy to see.

 

erinle8: This thread has two pictures of the X-Type thermostat housing off the car (bottom of page 1), and as viewed from below, under the front of the car (page 2):
