Overheating Problem in Mark V Fiesta
 

Hey, how's it going? Anyways the car is a 2002 1.3 duratec, the car is badly overheating after about 10 minutes, the mechanic has found that there is no coolant leaks, the thermostat is fine, the head gasket is fine, the rad seems to be fine... anyone have any ideas? Any help would be much appreciated!
