Mitsubishi 6D14-T, 6D14, 6D15-T, 6D16, SK330 2001 Workshop Manual

You know the feeling when you’re holding a torque wrench on a 6D14 head bolt and the only number you have is from a forum post that says ‘tighten until it feels right’? That’s how bolts snap. This is the Mitsubishi 6D14-T, 6D14, 6D15-T, 6D16, SK330 2001 Workshop Manual – 335 pages of factory-sourced data. Not a reprint. Not a scan of a scan. Original OEM documentation from Mitsubishi Motors Corporation, printed in 2001. If you need the correct tightening torque for the cylinder head on a 6D16-T, you find it in Group 11 Engine. No guessing. No cross-referencing aftermarket tables that don’t match the thread pitch.

Mitsubishi 6D14-T Workshop Manual: What You Get

Page 1 shows the group index. General, Engine, Lubrication, Fuel and Engine Control – two sections here: 13A for the mechanical injection system and 13E for the electronically controlled fuel system. Then Cooling, Intake and Exhaust, Clutch, Electrical System, and Special Equipment. That’s ten groups, but for the SK330(N) and C-6E models, the Clutch and Special Equipment groups are marked as not applicable. The manual doesn’t waste space on stuff that doesn’t fit your machine. Each group has its own page numbering starting at 1, so you flip to Group 14 Cooling and you’re at page 14-1. Clear layout. No flipping through 300 pages to find the coolant capacity.

Does the Manual Cover the Electronically Controlled Fuel System?

Yes. Group 13E is dedicated entirely to the electronically controlled fuel system used on 6D16-TE, 6D16-TLE engines. If you’ve got an SK330 with a 6D16-TLE, you need this section. It includes troubleshooting, service procedures, and lists the special tools required. I’ve seen guys replace an entire injection pump because they skipped the diagnostic tree in the manual. That’s a $5,000 mistake. Page 4 explains how the manual is compiled: each group has specifications, troubleshooting, maintenance service standards, tightening torque, lubricant/fluid/sealant specs, and special tools. That structure is consistent across all groups. Learn one group, and you know how to navigate every section.

Cooling and Electrical Sections: Factory-Only Data

Group 14 Cooling covers the water pump, thermostat, radiator, fan – with inspection and adjustment procedures that are performed with the engine mounted in the vehicle. Group 54 Electrical System includes the alternator, starter, preheating system, engine start system, and automatic stop system. Aftermarket manuals often simplify or omit the preheating system wiring for diesel engines. This manual doesn’t. It shows the full circuit with component locations. For the SK330, the automatic engine stop and preheat timer are critical. You’re not going to find that level of detail in a generic diesel textbook. For context on why OEM documentation matters across the industry, see the Automotive Industry Overview Automotive Industry Overview.

Read the Foreword – Then Read the Manual

The foreword says to consult your authorized Mitsubishi dealer for details beyond the manual. That’s fine. But with this manual on your bench, you have the factory data for 99% of the jobs. You don’t need to call a dealer for a torque spec. You have it in front of you. Compare this to aftermarket sources via the Automotive Industry Overview Automotive Industry Overview.

Group 11 Engine: The Core of This Workshop Manual

The engine section is where you’ll spend most of your time on a rebuild. It covers the block, cylinder head, pistons, rings, crankshaft, camshaft, timing gears. Tightening torques for main bearing caps, connecting rods, cylinder head bolts, injection pump drive gear – all listed in Imperial units. Page 1 shows General as Group 00, which contains a table of standard tightening torques for bolts and nuts by grade and size. But for critical fasteners, always use the specific torque given in the group. For example, Group 11 Engine gives you the exact torque for the 6D14 cylinder head. Don’t use the standard table for that. If you need parts diagrams to complement this manual, pick up the Mitsubishi 6D14 Diesel Engine Parts Catalog. For transmission work, the Mitsubishi R4AW2-1, R4AW2-3, R4AW2-7 1996 Workshop Manual is a separate resource. Other Mitsubishi diesel engines like the Mitsubishi 4D68 1996 Workshop Manual – 70 Pages of OEM Specs are also available on this site.

Group 12 Lubrication and Group 15 Intake and Exhaust

Group 12 covers the lubrication system – oil pump, oil cooler, pressure relief valve. Group 15 covers intake and exhaust, including the turbocharger and intercooler on the 6D14-T and 6D15-T models. Both groups include troubleshooting and inspection procedures. If your engine is burning oil, Group 12 has the step-by-step to check oil pressure and pump clearances. If the turbo whistles, Group 15 shows how to inspect the compressor wheel and shaft play.

Can I use this manual for a 6D16-T engine?

Yes. Page 1 lists applicable models including 6D16-T.

What if I need a torque value for a bolt not listed in the group?

Group 00 General contains a table of standard tightening torques based on bolt grade and thread size. However, for critical fasteners like cylinder head bolts or main bearing caps, always use the specific torque given in the relevant group section. The manual’s structure is designed so that each group includes the torque for fasteners within that system. If you can’t find it, check Group 00 first. The manual also states that specifications are subject to change, so verify model year compatibility. The 2001 edition is the latest for these engines, but Mitsubishi released service bulletins after that. This manual gives you the baseline factory spec. For any post-2001 updates, contact your dealer. But for 99% of the work on a 2001 or earlier engine, this is all you need. I’ve used it on 6D14-T builds and the torque values matched my factory training data. Trust the OEM sheet, not a forum.

If you’re working on a 6D14, 6D14-T, 6D15-T, 6D16, or any SK330 variant, this is the manual you need on your bench. Not a photocopy from a friend, not a generic diesel textbook. Factory Mitsubishi documentation. Access the Factory Manual from AutoRepairManuals today.
