Does the fan behind the radiator spin at a high rate at all times? Mine does and it concerns me. I did a flush of the cooling system and change the thermostat. Is it possible there is a blockage in the water lines preventing the coolent free flow? Or is it an electrical problem with the fan?

The fan is programmed to cylcle on and off not all the time when a certain temperature is reach and controlled by the computer-check the coolant temperature sensor/engine temperature gauge switch and fan relay could be sticking
