This product is a cylinder head gasket designed for Hisun 700 engines, part number 12250-007-0000. The cylinder head gasket is installed between the cylinder block and cylinder head to seal the combustion chamber, preventing leakage of high-temperature and high-pressure gases, while also preventing coolant and oil from entering the cylinders. Manufactured from high-quality multi-layer metal or composite gasket material, offering excellent high-temperature resistance, high-pressure resistance, and sealing performance. It is an essential replacement part during engine overhaul or cylinder head removal.

This cylinder head gasket fits the following Hisun and related brand models:

• OEM Matching: Part number 12250-007-0000 corresponds exactly to the Hisun original parts system, ensuring direct replacement.
• Quality Material: Made from high-temperature and high-pressure resistant gasket material, maintaining stable sealing performance under harsh engine operating conditions.
• Precise Dimensions: All oil passages, coolant passages, and bolt holes are precisely positioned for perfect fit with cylinder block and cylinder head.
• Leak Prevention: Effectively seals the combustion chamber, preventing gas leakage to maintain engine compression pressure; also prevents coolant and oil from entering cylinders.
• Maintenance Essential: A new cylinder head gasket must be installed whenever the cylinder head is removed to ensure reliable engine operation.

✅ Typical Symptoms of Cylinder Head Gasket Failure: Engine overheating, excessive coolant consumption, oil emulsification (white foam under oil cap), white smoke from exhaust, loss of engine power, low cylinder compression pressure. If you experience these symptoms, the cylinder head gasket may be damaged and needs replacement.

⚠️ Installation Note: Replacing the cylinder head gasket requires removal of the cylinder head. Thoroughly clean the mating surfaces of both cylinder block and cylinder head before installation, ensuring no old gasket residue remains. Place the new gasket correctly, paying attention to orientation and alignment. Tighten cylinder head bolts in stages following the torque sequence and specifications in your service manual. Start the engine after installation and check for leaks.
