Fastener Tightening Tolerances & Torque Sequence
Always lubricate fastener threads with clean engine oil prior to torquing unless dry assembly is specified. Tighten all fasteners in alternating spiral sequences starting from center bolts outward.
| Component / Fastener Location | Torque Tolerance Specification |
|---|---|
| Cylinder Head Stretch Bolts (M12x1.75) | Pre-torque 30 N·m -> +45° -> +45° -> +45° -> +30° |
| Connecting Rod Bearing Cap Bolts | Pre-torque 30 N·m -> +60° -> +30° angle |
| Main Bearing Cap Fasteners | Pre-torque 50 N·m -> +60° -> +45° angle |
| Rocker Arm Bracket Retaining Nut | 55 N·m (41 lb-ft) |
| Fuel Injector Hold-Down Claw Bolt | 25–30 N·m (18–22 lb-ft) |
| Flywheel Mounting Bolts (M12x1.5) | Pre-torque 30 N·m -> +60° -> +60° angle |
