No, it wouldn't do that. I would get this http://www.factorychryslerparts.com...rmostat--sensor-ad-se/11944599/5047861AC.html . Includes the t-stat, sensor, housing and gasket for pretty cheap. Your local dealer may give you a good price if you print it off showing how low others go http://www.partsinthed.com/oe-mopar/5047861ac. The throttle body cleaning you could do, save money. Pretty simple really. IF you are still under powertrain warranty, 50k miles I think. Take it to the dealer.
