I have a 2004 dodge ram 2500 diesel and I use it for snow plowing. The truck keeps overheating and I don’t know why. It only over heats when the plow is on. I know that there is limited air flow when the plow is on, but it shouldn't be overheating. Even when I ride the plow 2in from the ground it still over heats. The fan shroud had been removed. Does this impact the air flow?
