Mitsubishi Triton, L200 Workshop Manual (2006–2013)

If you’ve ever pulled a head bolt on a 4D56 and trusted some third-party torque chart that turned out to be for a different year, you know the feeling. That sinking moment when the bolt strips or the head gasket leaks because the spec was off by 10 ft-lbs. This Mitsubishi Triton, L200 Workshop Manual for 2006-2013 eliminates that guesswork. It’s the exact same binder Mitsubishi service departments used – 558 pages of factory procedures, not some aftermarket rewrite. I’ve torqued more head bolts than most people have had hot meals, and I don’t trust anything that didn’t come from the OEM printer.

Engine Mechanical: Torque Specs and Overhaul Procedures

Section 11A covers the 4D5-SOHC engine mechanicals. You get service specifications, sealants, special tools, and on-vehicle services like drive belt tension adjustment, valve clearance check, and injection timing adjustment. The cylinder head gasket removal and installation procedures list the torque sequence and angle tightening values. Page 00-37 shows the standard part/tightening-torque table – that’s your go-to for every bolt on the truck. Don’t bother with generic internet tables; this is the factory data.

How to Navigate the 558-Page Workshop Manual

The manual is structured into groups. Group 00 (GENERAL) is where you start – it explains how to use the manual, defines terms, and gives the scope of maintenance. Turn to page 00-2 for the ‘How to Use This Manual’ section. It tells you exactly what each symbol and tightening torque indicator means. If you skip this, you’ll misread the instructions. I’ve seen it happen.

Diagnosis Function: Reading Codes Without a Fancy Scanner

The troubleshooting section (page 00-5) is not just a list of codes. It walks you through system operation verification, diagnosis functions, code charts, symptom procedures, and actuator testing. There’s even a ‘Check at ECU Terminals’ section and oscilloscope inspection procedure. For the common rail engines, the manual covers the learning procedures – injector identification code registration, small injection quantity learning, and supply pump correction learning. These are critical after replacing an ECU or injector. Without these steps, the engine runs rough or throws codes.

What Torque Values Are Listed in This Manual?

Every major fastener in the vehicle has a torque spec in the standard tightening-torque table on page 00-37. But the individual procedures also call out specific values. For example, the timing belt tension adjustment gives both the static and dynamic torque. The cylinder head gasket installation includes tightening steps with torque angles. You won’t find ‘tighten until snug’ in this manual – it’s all ft-lbs and degrees.

Common Rail Engine Learning Procedures

This manual is essential for anyone working on the later model diesels. The ‘What the Common Rail Engine Learns’ section explains the registration and learning procedures. If you replace an injector, you must enter the injector identification code via a scan tool. The manual gives the purpose and procedure. Then there’s the supply pump correction learning and idling learning. Mess this up and the engine might idle rough or fail emissions. The manual also covers how to handle past trouble codes and intermittent malfunctions – something most aftermarket manuals gloss over.

SRS Safety: Why You Follow Every Step

Group 00 includes the Supplemental Restraint System (SRS) service precautions. Page 00-30 lists the specific safety steps: disconnect the battery, wait 60 seconds, don’t use a multimeter on live circuits. Ignoring these can deploy the airbag in your face. The manual also tells you where to jack and lift the 2WD and 4WD models – support locations are vehicle-specific. Use the wrong lift point and you’ll bend the frame rail.

Frequently Asked Questions

Does this manual cover the 4D56 engine?

Yes. Section 11A covers the 4D5-SOHC engine mechanicals, including the 4D56.

What if I need the injector identification code registration procedure?

The manual includes that in the ‘What the Common Rail Engine Learns’ section. It explains the purpose (to match each injector’s flow rate to the ECU), the registration steps using a scanner, and the subsequent learning procedures for small injection quantity and supply pump correction. Without this, the engine may run rough or set a DTC. The manual also covers how to treat past trouble codes after ECU replacement – you erase them and then learn the idle. It’s a sequential process that must be followed exactly. Many DIYers miss the ‘LEARNING PROCEDURE FOR IDLING’ step and end up with a high idle.
