First off you Cannot take the thermostat out in a late model car without it overheating, first thing I would do is get the proper one back in place and retest it ... you also must use the vents on the top of the engine to release the trapped air in the system if you dont do that it will overheat ..
there is one by the top hose and one by the heater hose on the left side of the engine compartment they look like little 7mm nuts on top of another nut ..
they must be loosened to allow the trapped air out of the system with the engine running ..If you have any reservations about how to do this I would suggest taking it to a dealer or a mechanic before you do any damage with further overheating..
