Replace the thermostat. It will be fine after that. I know thats what everyone says anytime there is an overheating problem but in this case with the way the system works and it has been working fine up to this point, it's gonna be the thermostat.

Your thermostat is located under the thermostat housing, which is what the upper radiator hose clamps to on the top of your engine. Basically, you need to start with a cold engine, drain your radiator, then unclamp the upper radiator hose from the engine. Remove the bolts from the thermostat housing, and gently tap on it to remove it. clean up the mounting surfaces on both the engine and the housing, and install a new thermostat, and new gasket. tighten to proper torque, reconnect the radiator hose, then refill up the radiator and cooling system.
