Could reinstalling a radiator cause the thermostat to go bad?

What is your question?

After a minor front end crash, the body shop removed & reinstalled the radiator and replaced the radiator support. After we got the car back it overheated. The Subaru shop performed a system pressure check and no leaks were detected. No exhaust gas was found in the coolant. They determined the thermostat had melted and needed replacement. Could this have been related in any way to the body shop's work on the radiator?

What makes this problem better or worse?

Engine is not overheating since thermostat was replaced

How long has your 2015 Subaru Forester had this problem?
