Yep, this manual is compatible with the 6.6L Duramax V8 diesel on the ’05 2500HD. You’ll get the real-deal engine stuff: fuel system (injectors, rails, pump), turbo basics, glow plug/relay checks, compression and leak-down, cooling system service, torque specs, and the usual diagnostics. If you’re chasing a no-start, smoke, or low-power issue, the flowcharts and specs are in there 👍🏻
