i.e. Make sure the thermostat is not stuck closed or the water pump is not malfunctioning.

Over heating as in the sense of the radiator cap blowing off pressure or just a high reading on your gauge?

The cooling system is not properly dissipating the heat produced by the engine, WBMG ;)

If you overheated the engine, the thermostat needs replacing. The wax pellet mechanism that operates the thermostat is usually ruined after only one overheat. Make certain that when you replace it you orientate the thermostat exactly the way it was, (right side up and sometimes forward as well). Check the cap operating pressure and fluid level of coolant overflow container and radiator as well. You may have a blocked hose from the coolant container to the radiator neck. Check water pump operation and belt tension.
