I know a little that may be helpful.
The thermostat housing is located and connected on bottom left hand area of the radiator. It is a black plastic thing connected to the engine and connected to the radiator with a hose. Not sure how to take it of exactly but shouldnt be too difficult. Be careful cause you need to drain coolant first.
Hope it helps. gonna be changing mine soon , but need to put new fuel filter on mine as well.
