It is located on the passenger side, towards the top and front of the engine. It is an assembly that includes the pipe that the upper radiator hose attaches to. The top bolt is very easy to get to with a socket. The bottom bolt is where I got stuck. I could not find a way to get a socket on it even using a universal joint. There is no way to get a wrench on the bottom bolt. It looks like you may have to take the Power Steering pump and it's mounting bracket off in order to get the bottom bolt out and back in. I am taking my TB to the shop as I don't want to tear it down that far just to replace the thermostat. If someone finds a way to deal with the troublesome bottom bolt, please update this answer.
....HERE IS THE CORRECT ANSWER...
