check your radiator first, when it's hot feel for cold spots if there are then your rad may be bad. if it's a bad tstat, normally it will overheat very quick. make sure your coolant level is full as well as it may have dropped since the t-stat change.

Check the radiator cap and if bad, replace it and bleed the system and retest. If radiator still deplete, get a pressure test done. Most probably the head gasket is bad.
