Working in a garage years ago, one of the most common causes of overheating that I found was that someone put the thermostat in backwards. The temp sensing pellet goes toward the engine. If it is going past 240 after shutdown and the pressure cap isn't raising, then I would also check the temperature gauge (and the cap) as well.
