Hi Sulthan, I've never heard of replacing only one fan on these cars as they come in a pair when you buy new ones. I'm assuming that you are having an over-heating problem. Sometimes it is not the fan but the fuse under the hood. If you open the hood and look towards the firewall on the driver's side you will notice a black box. Remove the cover and you will see several fuses. These aren't the traditional small fuses that you think of under the dash. These fuses are about an inch square. When standing at the fender, the big fuses futherest from you on the right side of the box towards the engine are the ones that you want to look at. First, try tapping on these 4 fuses lightly with a scew driver or something similiar. The car should be running and at operating temperuture or a little above. If this doesn't make the fan(s) come on then mark the fuses first and try swapping them around. Of course if this works then you will know that you've only got a fuse problem. If this doesn't work try tapping on the fan motor lightly. If it is still trying to run hot,let the engine cool down and remove the thermostat. It should be in the closed position. Boil some water on the stove and drop the thermostat in the boiling water for 3-4 minutes and see if it opens up. If it don't, then replace the thermostat. Take your old one to the parts store with you because there are at least 2 different kinds of thermostats in this car. If this doesn't solve your problem then you may have a cylinder head issue. If this is the case, have a compression check done to see if you have problems in this area. I hope this helps you. John

My SVT FOCUS temperature gage keeps going to the red. I changed the thermostat and it's still trying to overheat. I have a Haynes book on FOCUS 2002 to 2005 however; it does not explain how to change...

The radiator fan is most likely to blame. When the temp goes above the normal level the fan should kick on.. If it does not, you need to troubleshoot the rad fan. (Under hood etectrical box, fuse / relay/ etc.)
Also there are 2 of them (fans). The 2nd one is a booster for when the AC is on, to dissapate more heat. Try turning on the AC and see if 2nd fan kicks on. This can often help prevent serious overheating.
Good luck.

Need to know where the fan motor and resistor is located on the 2003 Ford Focus. Car overheats while idling, driving, in park, and it'll still overheat when the heater is on. Tell me what site I can find...

Cars usually overheat when the thermostat is faulty, coolant level is low, or the water pump fails. If your cooling fan on the radiator does not kick on shortly after the engine reaches operating temperature, you may have a bad cooling fan, cooling fan relay, or cooling fan fuse. If your engine is overheating, start by checking the fluid level, and installing a new thermostat.

A blower motor resistor is the device that controls a car's cabin heating and air conditioning unit's fan speeds. This usually won't cause the engine to overheat, your A/C fan may not function or only function at one speed. Here is a Blower Motor Resistor from Autozone:

Ford Focus LX 2.0L 2003: radiator fan not working

This can be caused by a few things. First, the fan motor may be burned out or the temperature switch may be malfunctioning so the fan doesn't engage. The thermostat may also have gone out which prohibits the coolant to circulate through the engine and radiator thus cooling your engine.
