Question about 2001 Ford Focus
OVER HEATS COOLANT FAN NOT CUTTING IN FITTED NEW ECM THAT DID NOT WORK TEMPERATURE GAUGE READS NORMAL BUT ON LIVE DATA TEMPERATURE READS 104 ?
On my 2001 Focus Zetec 2.0L, the radiator fan only worked with the air conditioning turned on (as in no low speed - engine would overheat while idling or in traffic, but was fine as long as the A/C was on). The fix was to replace the radiator fan resistor assembly located in the fan shroud between the fans.

The fan should not come on at 104 unless you have the a/c turned on. Before you go tearing the harness apart, hit the simple things. How many miles are on it? is the cooling system in good condition; coolant, thermostat, radiator flow? Is it possible the cooling system has an air pocket in it, it is very common and will cause am overheat every time.Is it actually overheating in the first place? Newer cars run at 220-245*f . Check it with a temp probe, (in the coolant) if its not that hot and its pushing out coolant its a flow problem or possibly cylinder pressure pushing the coolant out (head gasket).

Hi firstly check your fuses if ok check the cooling fan wire it direct to the battery see if it works if ok find the tempeture switch which operates the fan by connecting both wires together with ignition on see if fan works if not the relay is next after that you arse looking at wiring looms rubed through or bad grounds yates210456
