Check the following:
Thermostat
Water Pump
Coolant level IN THE RADIATOR, not the Overflow tank
Verify that there's coolant in the overflow
Check for leaks under vehicle, or a sweet smell coming from motor.
Look for white smoke coming from tailpipe when engine is warm and idling(Bad Head Gasket)
If all is good, take it to a shop and have them check for a bad head gasket. A sniff test is an easy indicator, it basically "sniffs" the air coming out of the radiator cap and tests for the presence of exhaust gases. Keep in mind, if they do a sniff test and it comes up negative, you still might have a bad head gasket.
Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat and let me know if you have questions.
