You are worried over a none issue.
Disconnect and plug the EGR vacuum circuit, it is useless + sludge's the intake ports/manifold.
The device in the thermostat housing is a temperature sensor, look for the wire, but if all the gauges work = someone may have swapped out a corroded thermostat housing for one from another engine.
