Before installing the Weichai cylinder head (1000873864), inspect the engine block surface for warpage or damage. Clean thoroughly and ensure no debris remains in coolant or oil passages. Use a new head gasket and follow the manufacturer’s tightening sequence and torque specification (typically 120 Nm in 3–4 stages). After installation, refill coolant, bleed air, and run the engine at idle first before loading.
