    Fan Clutch?

    Hey guys.

    I don't think my fan clutch is working correctly.

    Watching the RPMs on the MM3, it never gets above 346 RPMs.

    Before, I could hear it change speeds when the AC clutch engaged, but now it stays the same.

    Any thoughts?

    2014 2500 on Fuel rims, custom aluminum grill emblem, mm3 DRD tuned, 4” jamo tbe exhaust, led fog lights, steering box brace, took Vinyl off doors.

    Is your truck over heating?
    If it’s getting cooler where you live, it may not kick on every time the AC clutch engages.
