I have a 1000 Doge 3500 4x4 with a 5.9 cummins engine, the trouble is this: iI use it as my welding truck and everytime I am travelling at a low speed or logging thru mud in low gear (sometimes just driving up a hill) the temperature gauge starts to rise to the point where I have to stop a let the vehicle cool down a bit or open the hood. Can you please help me determine what might be causing this?
