2. Cylinder Head Bolt Torqueing
Most diesels use a simple 3-step torque. The 4M42 uses a torque-to-yield procedure:
- Step 1: 49 Nm
- Step 2: 90°
- Step 3: 90°
- Step 4: 90° The manual states these bolts are one-time use. Reusing them risks snapping the bolt in the block.
The Pirated PDF (Risky)
Found on forums or eBay for $10. These often miss pages, have poor scan quality, or are for a 4M40 (older engine). Warning: Using a 4M40 manual on a 4M42 will lead to wrong torque specs and engine damage. Step 1: 49 Nm Step 2: 90° Step
1. General Information & Identification
Before turning a wrench, the manual helps you identify your specific engine variant. The 4M42 has different power ratings (110kW to 130kW) depending on the chassis. This section details engine serial number locations and specific tooling requirements.
The Genuine Factory Manual (Best)
Produced by Mitsubishi Fuso. It is expensive (often $150–$300) but includes every TSB (Technical Service Bulletin) and precise fluid capacities (e.g., 8.5 liters of oil with filter). Format: PDF or DVD. have poor scan quality
The Haynes/Clymer Manual (Good for basics)
These are general guides covering multiple engines. They lack 4M42-specific ECU pinouts and torque angle specs. They are fine for oil changes, not for head gasket replacement.
Regular maintenance tasks and intervals (what the manual emphasizes)
- Engine oil and filter: change at manufacturer intervals (check manual for km/time)
- Fuel filter replacement and bleeding procedure after filter change
- Air cleaner inspection and element replacement
- Valve clearance inspection/adjustment
- Timing gear/belt/chain inspection and replacement intervals (follow manual)
- Coolant change and system pressure check; thermostat inspection
- Turbocharger inspection (VGT actuator and vane movement)
- EGR system inspection and cleaning (carbon buildup)
- Diesel particulate filter (DPF) regeneration/inspection where fitted
- Electrical system checks (glow plug function, charging system)
