Wanted to know if there are any torque specifications for the thermostat housing bolts. And is there a sensor connected to the thermostat housing?

It does not appear there is a sensor attached to the housing, but the harness may be clipped to it.
Please see the info below and let us know what questions you have.
Thanks
