It depends on the condition in which the vehicle overheats.
If it only overheats when you're in traffic or at a stoplight, the problem MAY be that the radiator fan isn't working properly.
If it overheats when you're on the highway or under normal driving conditions, it COULD be any of the following:
Thermostat. A sticking thermostat can either stick closed, in which case the engine will overheat immediately or it can stick open, preventing the engine from heating up to normal operating temperature. Sometimes a thermostat will sometimes stick open and sometimes stick closed.
Radiator. A blocked radiator will cause an engine to overheat rather quickly. A '97 is old enough that the radiator can be blocked internally, especially if the coolant has not been properly maintained.
Water pump. If the vanes of the water pump have worn out the pump may not be able to move enough coolant to keep the engine cool.
Head gasket. If the engine has EVER been significantly overheated it could have damaged the head gasket. A damaged head gasket usually causes the coolant to blow out the coolant overflow.
Cooling fan. A cooling fan problem can be caused by either an electrical problem (sensor, fuse, switch...) or a faulty fan motor.
If the problem is a bad thermostat, replace it with a new one.
If the problem is a blocked radiator, you CAN take it to a qualified radiator shop and they can often clean it for you.
If the problem is a worn water pump, the only solution is to replace the water pump.
If the problem is a faulty head gasket, you'll need to have the head removed, resurfaced and replace the head gasket.
If the problem is the cooling fan, you'll need someone to trace down the exact nature of the problem.
