    Hi guys
    Hope everyone had a great X-mass and new year. I'm looking for some assistance on an 03 2500HD that is overheating. I'm running an 8' Boss straight blade. The overheat only occures with the plow installed during regular driving. I have tried raising, lowering and angeling the plow with no success. As soon as the plow is removed (while driving normally), no overheating occures. Any help would be appreciated. Thanks Mike

    How fast you driving? My 01 gets warm if I forget to lower the blade a little at highway speeds but once I do it drops back down. Around town I dont have any problems.

    My 04 w/ 6.0L 8' Fisher HD w/snowfoil will occasionally get hot on the road. Same issue blade usually to high, also angling it a bit more helps.

    Have you cleaned your radiator fins. A good rinse with the hose might help.
