    Yep, and a good radiator cleaning might help too.

    drive with the plow as low to the ground as possible. This will allow more air to hit the radiator. Some plow brands, such as Blizzard, offer an air foil to direct air to the radiator.

    i can drive it low to the ground and the heat on high, but i wanted to not have to do that, im hoping the fan clutch will eliminate that...

    What speed are you driving at when it overheats? If your at or close to highway speeds you must do as Sven suggests and drive with the plow low.

    Could they tell if your clutch was bad?

    I'd say clean the radiator first. My 3500HD will spike a bit and turn my fan on when running down the highway in the winter with my plow on, but it's never over-heated.

    Sometimes just a bit of an angle will help with air-flow too.

    Angling and dropping should cover it. Upgrading the clutch or adding an aux. fan, is probably just treating the symptoms, instead of curing the problem, try having the dealer do a power flush on the cooling system, and of course check your thermostat.
