I'm not familiar with your exact car but a friend of mine had a similar problem the solution was to replace the electrical relay for the cooling fan. Consult a wiring diagram to see if there is a relay (there should be) and replace it.
The other possibility off the top of my head is a short in the wiring somewhere. Power the fan directly and ensure it works fine. If the fan is OK then the problem is likely in the wiring or wire connectors somewhere. That should help narrow down the problem. Good luck!

replace coolant sensor connector?if so can u get a thermo lazer gun to check the block temp? this will tell u if the gauge is incorect,,,go ahead a bleed all the air out of cooling system and see if that does the trick

Was the car over heating before the water pump and head gaskets were replaced? Putting in a new Radiator will make it run even colder.and take even way longer than the one hour it is already taking to warm up.The computer in the car commands the engine cooling fan On/Of at a predetermined temperature.It receives this data from monitoring engine sensors such as the engine coolant temperature sensor.So if it is defective and the computer is not recognising the defect it thinks that the engine is running hot when it is realy running cold and will command that the cooling fan be on.Resulting in the fan running in 24-7 as you put it. If you want the engine to warm up faster and the cooling fan to operate normaly then I would replace the engine coolant temperature sensor and the relay for the fan circuit as well. If you need to talk to me further about this you can use the reply box below. Please let me know how this goes for you and I hope this is usefull for you. Good Luck and have a good XMASS.
