A 6D14 on the stand with the head off raises one question first: what goes back, and to what figure. The Mitsubishi 6D14 shop manual PDF (OEM 97821-02030) answers it across 490 pages, covering six variants of the 6D14, 6D15 and 6D16 diesel engine family, naturally aspirated and turbocharged. Electrical work fills nearly a third of the book, with wiring diagrams tracing the alternator, starter and automatic stop circuits, while the engine chapter walks you through cylinder head and valve mechanism, pistons, connecting rods, liners and camshaft. Injection pump and nozzle service, turbocharger, lubrication, cooling, clutch and air compressor each get their own chapters, and troubleshooting charts link a symptom to its cause. Check each glow plug for 3.8 Ω at normal temperature, and bring the M14 head bolts to 78 N·m before the final 180° turn. Angle-torque head bolts forgive nothing. Print the bookmarked, searchable file and let your reassembly pages take the oil stains on the bench.
