Check the 12v to the switch and see whats up. The ignition switch may be worn out. There should be an overflow bottle which should be filled with water regardless of the radiator level. When the cap pops, it sends the water into the bottle but as soon as things simmer down it sucks the water back up. What you can do is put your hand on the rubber hose from the thermostat to the radiator or the top of the radiator to see if it gets hot when the thermostat opens. If it doesn't get hot and the gauge is getting really high then replace the thermostat, its really easy, just undo those two bolts on the top of the thermostat housing and pop in a new one, and have a new gasket ready for it too. Other than that, make sure the gauge reads properly and stuff. If you're really wanting to dig in you can pull the radiator out and flush it with some sort of radiator cleaner or just use a water hose. Sometimes that bottom hose on the passenger side gets clogged with gunk and impedes the flow.
