Yep, absolutely. This is the right manual for the 2003 Ram 3500, and it's packed with the full, in-depth coverage for the 5.9L Cummins diesel engine.
It includes all the detailed procedures you'll need, from the complex diagnostics for the fuel system right down to a full teardown and reassembly of the engine.
For any work on that Cummins, this is the manual you want to have on hand.
