Hello everyone with the weather changing and the Esprit spending more time inside I've decided to change the radiator fluid and put in a new thermostat. I just ordered a new one from JAE so it should be here in a few days. The question I have is I see where the thermostat housing is near the fire wall in the Y joint for the the return fluid and see what appears to be 3 bolts holding it on. The 2 on the side seem easy to get to but the 3rd is slightly under the top cover and looks difficult to get to. Can you do it with out taking off the top of the engine? Any help here would be greatly appreciated. If anyone has pics or where I can find them that would be a great help as well. As always thanks in advance.
