Ever since i got my truck back from the shop last tuesday, my truck has had a small antifreeze leak. As the time pasted i would just add coolant to make sure it was full. Here lately i would top it off and drive for about an hour and my low coolant light would come on. It looks like its coming out of the front drivers side of the motor. When i look under it is sprayed everywhere. Im new to the diesel world and would appreciate any advice or wisdom that yall may have. Thanks again.

They aren't terrible. There is a writeup here that gives good instructions on how to do the work. A search should find it pretty easily.

While you're in there do a compression test. Some times the coolant system gets over pressurized from a bad head gasket. Then the pump starts leaking through the safety port.
