Installation Guidelines for 080V90020-0383 Cylinder Head Bolt:
Liste de contrôle de pré-installation:
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.Lubrification: 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.
Étapes d'installation:
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.
Avertissements critiques:
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 d'opération.
Monitor for coolant/oil leaks indicating improper sealing.
Avoid high-load operation until retorquing is completed
