Depends on the situation (i.e. if it's out of the blue or if work has recently been done on the car). 1. If you just the fluids checked and the radiator flushed out, there could be an air bubble in the radiator. The best thing to do is keep the car running with the heat on high. Keep adding water. Heat rises, so hopefully after awhile, the heat being on will force any air bubbles to the top and out of the radiator. 1a. Also, if the radiator has recently been flushed and there was a significant amount of dirt and debris in it, that same dirt and debris could have been plugging a hole in one of the hoses. Somebody could also have previously used the worthless Stop Leak solution which could be messing with the radiator system as well. 2. It could be as simple as a bad seal on the radiator cap. The worst caps out there are the kind that have a small lever you can lift to bleed the air before taking off the cap. These often do not seal properly, which in turn could cause the car to overheat. 3. Of course there could be a leak in a hose or in the radiator itself. 4. The radiator could need flushing so badly that the dirt and debris could have caused rust, which could corrode the radiator cap and/or ruin the thermostat. I probably missed some major and obvious other reasons, but those are my personal experiences with my 98 Dodge Neon Sport.
