Hi
I'm Just Wondering how to test my radiator fan on my ford mondeo mk2
thanx Dave

 

start ur engine up and let it run and if it does not turn on at the certain temputer then it will be broke mate

 

you can also wire it to a battery to make sure the fan actually works

 

Take off the wiring plug on the fan switch and bridge the terminals together with a paperclip or something. Turn ignition on and it should come on.

 

Don't need to do any of the above, just unplug the wire from the CTS sensor, the ECU one, fan will come on and run all the time this is disconnected, also shows you cts signal is being received then as well.
