Question type: Maintenance & Repair

07 Mur Mountaineer 4.0 V6 RWD
I have replaced the radiator a while back and now more times then not the
fan sound like a plane taking off . i idles fine and as the rpms increase so
does the whooshing sound of the fan, This comes and goes . at times i see
the temp needle increase as the sound is happening but doesnt get to high
and then settles back to normal within a minute .

I swear it is electrical the way it comes and goes , is there sensors or
controllers /i need to be looking at . everytime i bring it to the shop it never
acts up

Your radiator fan has an electrically controlled clutch. First make sure that you plugged the clutch back in after replacing the radiator. If it still makes noise, get a shop manual and check the electric clutch operation

the radiator install was a few months back and everything was fine after . this a new problem and been looking into the Coolant Temp Sensor - Ford (3L8Z-12A648-A) which i believe controls the fan
