Genuine Sinotruk HOWO 080V90020-0383 Cylinder Head Bolt (M14X2X152)
This authentic Sinotruk HOWO cylinder head bolt (Phần không: 080V90020-0383) is engineered to exact OEM specifications, providing critical clamping force for cylinder head sealing under extreme engine conditions. Designed for heavy-duty applications in HOWO truck engines, this high-tensile bolt ensures uniform pressure distribution across the cylinder head gasket, preventing compression loss and coolant/oil mixing. The precision-threaded design (M14X2) and optimized length (152mm) guarantee perfect engagement with the engine block, maintaining structural integrity under high-temperature and high-pressure operations.

Installation Guidelines for 080V90020-0383 Cylinder Head Bolt:
Pre-Installation Checklist:
1.Inspection: Verify bolt length (152 mm) and thread condition (M14×2). Replace if threads are damaged or stretched.
2.Cleaning: Ensure engine block threads are clean and free of oil/debris. Use thread chaser if necessary
3.Lubrication: Lightly coat threads and underside of bolt head with engine oil unless specified otherwise.
4.Tool Preparation: Use calibrated torque wrench and angle meter for accurate tightening.
Installation Steps:
1.Hand-Tightening: Start all bolts by hand to avoid cross-threading.
2.Initial Torque: Tighten bolts in manufacturer’s specified sequence to 50 Nm.
3.Angle Tightening: Apply additional 90° rotation in the same sequence.
4.Final Pass: Repeat another 90° rotation (total 180° angular turn) for proper stretch.
5.Verification: Re-check torque values after 10 minutes of operation.
Critical Warnings:
Never reuse old head bolts – always replace with new ones during engine reassembly.
Avoid over-torquing – stretching beyond yield point causes permanent damage.
Follow exact tightening sequence to prevent cylinder head warpage.
Use only calibrated tools – inaccurate torque wrenches risk engine damage.
Post-Installation:
Retorque after first 500 km of operation.
Monitor for coolant/oil leaks indicating improper sealing.
Avoid high-load operation until retorquing is completed
