Is the Ford F150 radiator fan always on?
Is the Ford F150 radiator fan always on? @bhurry yes they are loud but for as long as your temp is good the fan is working properly. No, that is not related to the resistor. The fan does turn on with the AC it is designed like that. Just a heavy duty fan.... I have the same problem and I have never in my 29 years ever heard any truck fan as loud as mine and ac sucks Why are my coolant fans not running when AC is turned on? Coolant fans not running when ac is turned on. AC...
