I've not noticed before but the radiator fan runs constantly at low speed. This seems to be irrespective of the engine temp. The car runs 'spot on' and shows no signs of overheating, and I haven't left the AC turned on. So, I plugged in my trusty Fordscan gadget which showed no faults. It also ran the a PCM test procedure, including fan test and was all good. I am quite new to my cmax but I guessing the fan should only run when it needs to?
