Haval Exhaust Camshaft Timing Gear - 1021210XEC01

⚙️ Part Name: Exhaust Camshaft Timing Sprocket / VVT Pulley

🔢 Original Part Number (OEM): 1021210XEC01

• 🔄 Interchange/Alternative Number: 1021210AEC01
• 📍 The entity: The exhaust system is mounted at the front of the exhaust camshaft.

🔧 Mechanical function and role:

• It transmits synchronous motion from the crankshaft via the timing chain to the exhaust camshaft.
• It acts as a gear driver for the Variable Valve Timing (VVT) system to precisely adjust the timing of the opening and closing of the exhaust outlet valves according to the engine speed and load, thereby improving fuel efficiency, reducing emissions, and increasing torque.

🚘 Compatibility and motors:

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

⚠️ Key signs of damage or corrosion:

• 🔊 Rattling or clicking sounds coming from the front of the engine, especially when starting from cold.
• ⚠️ The Check Engine light is illuminated and timing misalignment codes are recorded (such as P0014 or P0016/P0017).
• 📉 Weakness and fluctuation in torque and acceleration, and jerking at low speeds.
• ⚙️ The teeth of the gear may wear out, which may lead to the timing chain slipping or the timing going out of alignment.

💡 Technical Tip: When replacing the timing/VVT gear, it is always preferable to inspect and change the timing chain, tensioner and guides (complete timing set) to ensure that the teeth fit smoothly and to prevent rapid wear of the new part.
