Make sure the coolant level is full. Could be as simple as needing a thermostat. If you're not a do it yourselfer take it to a shop and have the cooling system serviced. They will flush and pressure test the system, install new coolant and maybe a new thermostat and pinpoint any other problems if there are any.
