Shaking is usually from the engine misfiring. Not necessarily related to the thermostat housing, but could be an indicator the engine needs general servicing. Start by getting the CEL/DTCs read (can be done for free at most parts stores), then address the misfire first. If the thermostat housing is cracked check you have proper coolant levels. Get it replaced soon along with the thermostat.
