Simple Installation Notes:
Important: Cylinder head bolt installation is critical and often requires a specific torque-to-yield procedure and sequence. The following are general guidelines. Always refer to the official Sinotruk service manual for the exact procedure, torque sequence, and specifications.
Safety First: Ensure the engine is cool and the vehicle is securely parked. Disconnect the battery.
Cleanliness: Clean the bolt holes in the engine block thoroughly. Any debris or oil can affect torque readings and clamping force.
Lubrication: Apply the manufacturer-recommended engine oil or specific lubricant to the bolt threads and washers.
Initial Torque: Hand-start all bolts to avoid cross-threading. Using a calibrated torque wrench, tighten the bolts in the correct sequence (typically from center outwards) to the initial torque value specified in the manual.
Final Torque/Angle: Many modern head bolts, especially torque-to-yield types, require a final angle tightening (e.g., additional 90 or 180 degrees). Use an angle gauge for accuracy.
Re-check: Some procedures require a re-check of torque after the engine has been run and cooled. Consult the service manual.
