Haval Intake Camshaft Timing Gear - 1021110XEC01

⚙️ Part Name: Intake Camshaft Timing Sprocket / VVT Pulley

🔢 Original Part Number (OEM): 1021110XEC01

• 🔄 Interchange/Alternative Number: 1021110AEC01
• 📍 The entity: Intake — Mounts at the front of the intake camshaft.
• 🔁 Opposite side (exhaust): 1021210XEC01 / 1021210AEC01

🔧 Mechanical function and role:

• It transmits synchronous motion from the crankshaft via the timing chain to the intake camshaft.
• It acts as an intelligent operator for the Variable Valve Timing (VVT) system to advance or delay the opening of the air/mixture intake valves, to achieve maximum combustion efficiency and a fast throttle response at various engine speeds.

🚘 Compatibility and motors:

• ⚙️ Engine type: Great Wall/Haval 2.0L GW4C20 and GW4C20B turbo petrol engines
• 🚙 Compatible models (GWM / Haval / Tank):
  • Haval H9
  • Haval H6
  • Haval H8
  • Tank 300 (2.0T gasoline)
  • Great Wall Poer / P-Series (Gasoline)

⚠️ Key signs of damage or malfunction:

• 🔊 A metallic clicking or ringing sound from the front of the engine (engine front) when starting up or during deceleration.
• ⚠️ The Check Engine light is illuminated and intake timing codes (such as P0011 or P0016) are recorded.
• 📉 Engine misfiring and rough idle with weak torque and acceleration.
• 🛢️ Internal leakage of engine oil pressure within the VVT mechanism, causing it to lose response accuracy.

💡 Technical Tip: To maintain the efficiency of the VVT pulley and prevent the accumulation of deposits inside its fine oil passages, it is always recommended to use the approved oil viscosity and adhere to the oil change schedule, while checking the tensioner and timing chain when replacing the gear.
