Anybody know where this is? Keep getting a code.

in the fan clutch.

 

should the fan be fairly easy to spin when cold? I thought they were pretty stiff. Mine doesnt seem like it moves as much air at a idle. If I remember right then it would make my hair blow around when I would put my head where I could see the blades(that post is just asking for a joke). Also when should it kick on. Mine used to kick on at 218 but now I cant even tell you with any consistancy when it does.

So if the sensor is in the fan then chances are with the other issues I am having then replacing the fan clutch should eliminate the fan sensor code. THANKS
