Haval engine head gasket - 1003200XEC05

⚙️ Part Name: Cylinder Head Gasket

🔢 Original Part Number (OEM): 1003200XEC05

• 🔄 Interchange/alternative numbers: 1003200AEC01 / 1003200XEC01

• 📍 Location: It is installed between the lower engine block and the upper engine cylinder head.

🔧 Mechanical function and role:

• 🛡️ Combustion chamber compression: Sealing the gap between the head and the block completely to prevent the escape of air pressure, fuel, and combustion gases under the high pressure of turbo engines.
• 💧 Insulating the cooling and lubrication passages: Preventing the coolant (radiator water) from mixing with the engine oil as they circulate between the head and the block.
• 🌡️ Superior heat resistance: Manufactured with Multi-Layer Steel (MLS) technology to withstand thermal expansion and extreme pressures without deformation or burning.

🚘 Compatibility and motors:

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

⚠️ The most prominent signs of head gasket damage (hair/face burn):

• 🌡️ Frequent and unjustified rise in engine temperature and boil-over radiator water, which comes out of the reservoir.
• 🥛 The engine oil turned a milky color similar to (tahini/Nescafe) as a result of water mixing with the oil.
• 💨 Thick, continuous white smoke coming out of the exhaust with a coolant smell (radiator water burning inside the cylinder).
• 🎈 There is excessive air pressure and bubbles inside the radiator reservoir immediately after starting the car.
• 📉 A gradual and continuous decrease in cooling water without any visible external leakage.

💡 Technical tip when making changes:

• The flatness of the cylinder head surface and engine block must be checked with a precise hour and level ruler to ensure there is no warping caused by heat, and a lathe scan should be performed if necessary.
• It is always recommended to replace the cylinder head bolts with new ones and tighten them with a torque wrench according to the sequence and tightening angles specified by the manufacturer.
