Can A mechanic cause any damage when replacing a serpentine belt

My power belt broke on my car. I took it to a mechanic called pepboys and they replaced the belt. My car broke down that same day. My car was overheating and the heat level was going on up after I put coolant in my car. I never had problems with my car overheating before. I was wondering could they have down something when replacing my car.
