E46 Radiator fan is not working

[BMWsociety]

Hi all UDM sifus....seeking for your advise.My brother his E46 got overheat last week. The mech managed to find out that 1 of the termostat already failed. He replaced all the hoses (included the one at the back of the engine) , expansion tank and the termostat and now the radiator fan is not working. But if he turn onn the air cond the fan running per nomal. From my undertanding if the fan is really kong of coz if u turn onn the air cond it will not working as well right ( correct me if i am wrong :7: ). Even fan is not working but if he start the car and let it idle for 20 minutes the tempreture still at 1/2.How to check if the radiator fan is already KONG or not.......TQ

There are 2 fans. One is the clutch fan and the other is the aux. fan.

Aux fan is motor driven and it should either be STOP or slow spinning, medium spinning or fast spinning. The speed is depend on the temperature sensor.

However, when the aircon is ON, the aux fan will cut-in regardless of the water temperature.

If the water temperature gauge is showing half mark, you dont have to worry. Panic when it starts to go above 3/4 mark.

So check the temperature sensor. It should be located on the bottom rubber hose (left side of the radiator)

You are looking at something like this.

Kedai potong option is still the best option if new fan is not affordable. However, there are some people who buy other fan motor and retrofit it back with the original fan blade. However, pls check on the type of motor used. I heard that some motors have 3 wires (really for DC motor???) and some have 2 wires.
