1. Clean crankshaft conical surface of oil, align locating key
2. Tighten bolts diagonally in stages, torque 180–200N·m, apply anti-loosening compound
3. Belt Tension: 6PK belt tension 800–1000N, avoid excessive tightness causing belt tearing or excessive looseness causing slippage
- Fault Association: Prior check this pulley for engine front-end noise, frequent belt breakage, unstable generator charging, intermittent air conditioning cooling, and large idle vibration
