No, the sheared off bolt is holding the t-stat housing into the intake </div></div>

So the short bolt is removed or still in the housing? If you can get the short bolt out I would try to rock the housing clockwise and ccw just to get some movement (using a ton of penetrating oil and a wooden or rubber mallet)
