    6.7 CUMMINS
    Hey everybody, long time lurker, first time poster. I wanted to get ya'lls opinion on an issue I'm having. Recently the fan has been staying on for the whole drive in my cummins. I guess the fan clutch never disengages. It sometimes does it intermittently, but this week it has been on permanently for 3 days straight. I'm about to lose my mind it is so dang loud and obnoxious. Also, the MPG is suffering. Anybody ever had this happen? I have an appt at the dealer on Monday, but I'm worried they are going to blow me off and say "it's supposed to be on when its hot out" etc.

    They do fail and the design is supposed to lock up in failsafe mode to prevent overheating.

    Possibly has failed, stuck, or functioning correctly. You didn't say what the ambient temp was for these 3 days. Assume it's under warranty, see what the dealer says.
