Functions and Effects
1. Cylinder Block and Cylinder Head Sealing: Seals the joint surface between the cylinder block and cylinder head to lock the internal explosion pressure of the cylinder, ensuring the cylinder compression pressure, and preventing cylinder leakage, power loss, and exhaust pipe leakage.
2. Water Passage Sealing: Isolates the engine cooling liquid passage to prevent the cooling liquid from entering the cylinder interior.
3. Oil Passage Sealing: Isolates the oil passage to prevent engine oil from flowing into the combustion chamber or mixing with the cooling liquid.
4. Medium Isolation: Separates the three media of gas, cooling liquid, and engine oil, preventing them from intermixing; also withstands engine high temperature and explosion impact loads.
Main features:
1. MLS Multi-Layer Steel structure (Multi-Layer Stainless Steel Plate), multiple layers of stainless steel plates stacked together, with a special temperature-resistant coating on the surface, not ordinary asbestos gaskets, suitable for ISG high-pressure heavy-duty truck engines.
2. Strengthened steel guard ring for combustion chamber holes, reinforced around the combustion holes of the cylinder to resist explosion impact and prevent cylinder liner damage.
3. Precisely positioned water and oil passage holes, with sealed reinforcement at the edge of the holes, resistant to high temperatures, high pressure, and corrosion by coolant.
4. Working temperature: -40℃ ~ +350℃, can withstand cylinder explosion pressure of over 160 bar.
5. Net weight is approximately 1.0 - 1.2 kg.


Cylinder Head Gasket, OE No.5558113, interchangeable 3693228, for Foton Cummins ISG11 / ISG12 engine, Auman GTL / EST heavy‑duty truck.
FAQ
Q: Which engine & truck fit this gasket?
A: Specially for 6‑cylinder Foton Cummins ISG11, ISG12 diesel engine, widely used on Auman GTL / EST heavy‑duty tractor, dump truck. NOT fit for ISF series, WP12, MC series engines. One engine uses 1 piece.
Q: Main functions
A:
1. Combustion chamber sealing: Maintain cylinder compression pressure, prevent gas leakage and power loss.
2. Coolant water‑passage sealing: Avoid coolant entering cylinder.
3. Oil‑passage sealing: Prevent engine oil mixing with coolant or burning in cylinder.
4. Separate combustion gas, coolant and engine oil, resist high temperature and explosion impact.
Q: Typical failure symptoms of broken head gasket
A: Engine overheating, bubbling in radiator, engine oil emulsification (milky white oil), white smoke from exhaust, insufficient power, low cylinder compression pressure.
Q:What is your warranty term?
A: 3‑month warranty for non‑artificial damage. Warranty void for distorted engine surface, wrong bolt torque, bending deformation during shipment.
