== == Next, you have to remove the radiator hose. It's the same one that you might have drained out earlier. You'll be able to see the thermostat housing pretty well from here. Once you've got the rad hose out of the way, you need to remove the black plastic on the side of the housing. With that gone, move on to the nastiest part of the job. The three bolts on the thermostat housing. The first one is easy, it's the one closest to you. but the one on the back is a pain. You'll need to push some cable out of the way, and get at it with your socket wrench. After this one, move on the the worst of the three. You'll have to do this pretty much by touch alone. Last time I did this it was in my driveway in about -18`C weather. Brrr. Don't let it frustrate you, it'll just fall out of your hands and down into the engine components, or worse, into that pan full of coolant you probably left under the engine compartment, ha ha ha.
Alright, if you've gotten this far, you're at the easy part. Take off the housing, and remove the old thermostat. You might need to pull it out with a pair of pliers or something, if it was cold when you did this (as it should have been, don't need to get coolant burns), then it'll be held by suction. Change the thermostat's gasket, put the new one in place and reverse the process. It'll go back together 100x faster than it came apart.
Hope this helps!
