By the way mousy ran off, I think he must have been up to no good. I looked at the wiring and saw nothing conspicuous. The hitemp light comes on about the same time that I begin to smell hot fluid, so I think its probably correct. As for the thermostat I was very careful to replace it just as I found it and your correct, it only fits in its proper position. Though the tractor is running properly I am going to dismantle the air intake system next. At the rear of the breather body it splits two ways, left to the filter housing and right to what looks to be a muffler/heat exchanger deal. I expect to find a nest in one side or the other. I visited the dealer from whom I purchased the tractor and talked to their mechanic. He felt there had to be an exhaust or air intake restriction. There is a valve on the exit exhaust of thins heat exchanger. Going to check those wires as well.
