No need to post the pictures. Here it is. As mentioned before, the factory repair manual doesn't have much info, so I have imbellished it with my recent experience: 1. Drain enough coolant to be lower than the thermostat. Unless you intend to replace all of the coolant, you don't need to drain it all. Be sure to open the radiator cap and the bleed screw before you drain or it won't really lower the level evenly. 2. Remove the fan. Remember...left hand threads...clockwise to loosen. 3. Remove the little tray below the oil filler cap. It's not fastened, you just pull carefully toward the front, and it slides off. 4. Remove the hose that's attached to the thermostat housing. 5. Remove the four (4) housing bolts, and carefully pull off the thermostat housing. Make sure to notice which way the thermostat is facing before you pull it out of the water pump assembly. 6. When you buy the thermostat at the dealer, the rubber O-ring comes with it. Make sure that they give it to you. There is no paper gasket that goes between the housing and the water pump assembly. 7. Unlike some other engines, they say that you are only supposed to use the O-ring, and that you don't need any sort of sealer or gasket along the joint. I'm a little superstitious about that, so I spread a VERY thin film of gasket sealer on the face of the housing. 8. Put the new thermostat in, and be sure that you get the O-ring in correctly. 9. Put the housing back on. 10. Torque the bolts to 7 ft-lb. 11. While you have the fan off, check the movement of the water pump shaft. If there is any play, or if it doesn't turn smoothly, the pump is about to go. This is difficult to check for with the fan attached. 12. Put everything back together the same way you took it off. 13. Don't forget to bleed the system after you add the coolant back in.
