My Ford 06 F250 fan clutch seems to be locked up when engine is running. How do you tell if the wires are on it correctly? Anyone know? All answers appreciated.
Not sure on an 06 but the ones I have worked on have a coil wound spring that when it gets hot allows it to lock up. the fan will always turn even when cold but you can usually hear a different pitch in the sound when they unlock and lock like going up a steep hill when its hot! I have seen the springs get weak where they stay locked up.
