What about the hoses? If the hoses are bad they may suck shut or collapse while the engine is running and you will never know it. Also the water pump may be bad and not circulating water. Replace it too and make sure you have a proper mix of water and coolant.

Make sure the system is free of air. Sometimes it takes a little time to bleed the system thoroughly. Also, you are probably relying on the dash guage for your reading, and it may not be correct. Use an automotive thermometer to get an accurate reading. It may be the temp sending unit mot giving a prpoer reading. Also maybe the rad fan sw (in some cars its the coolant temp sensor) is not functioning properly and puts the fans on late or not at all.

One other important thing to check is the radiator cap. Is the water boiling in your car? Usually if there is a lack of pressure the water will begin to boil, and usually if this happens you will visably lose coolant. If this isn't the condtion I would do what the others said. Make sure all air bubbles are out of system (check for a bleeder around the upper radiator hose, or top it off from the highest point on the cooling system) and check your hoses.
