Excellent. So far so good. I have drive the car a few times in about 20-30 minute intervals and the coolant levels have remained the same in both the radiator and the reserve tank. I still have not heard or seen the radiator fan kick on, so I will definitely get that checked out asap. I will continue to monitor the coolant levels diligently. Thanks again for all your help SIRacer, your input into this problem is very much appreciated.
