Is the engine temp switch on the thermostat housing or somewhere in the cylinder head. I don't see any wires coming off the thermostat housing. I think mine may be bad. The light comes on after running it a while. I am not losing any coolant and the coolant was recently drained and replaced (about 10 hours ago). I would like to replace the temp switch but not too excited about the $87 switch from New Holland dealer. I was wondering about a universal switch that closes at 210 degrees or so. Also thinking about changing to a gauge cluster. Any ideas or help is appreciated. Thanks
