My daughters car is overheating. She is unable to drive for a bit because of a broken leg, but my wife up there today and would like to take it to have it looked at.

It is a 2003 car, so a little older, but in pretty good shape. It overheated a few times, but now it is happening more often. Coolant might be low in the system (reservoir is full but that does not mean anything) or the thermostat, etc.

Need someone that will not take advantage of my wife and not be too expensive if possible. Any help appreciated.
