Check the thermostat first.
That sounds like the radiator is very efficient. I would suspect a bad thermostat not allowing the engine to actually warm up. This usually goes hand in hand with little or no heat inside the vehicle and poor mileage.
If you have tons of interior heat and the gas mileage hasn't started to get bad, then I would suspect a bad temperature sender.

Only thing is the temperature control can't select cool temps (it did for a minute)...only HOT air.
