There should be Hot and Cold markings on the side of the tank. It could be that your engine is not over heating - it could be a bad sending unit.

what is a bad sending unit???

It's the actual sensor that tells your gauge how hot the engine is. These things rarely go bad, so when they do, it can be puzzling.
