WHAT IS THE PURPOSE OF A HEAD GASKET?
WHAT IS A CYLINDER HEAD GASKET?
The cylinder head gasket is one of the most important engine components but also one of the most fragile. This is a special seal because it plays a major role in the proper functioning of the engine . Before the law prohibiting asbestos in motor vehicles, the cylinder head gasket consisted of an asbestos sheet covered by two sheets of copper or aluminum and reinforced around the various holes of metal rings. Today, they are composed mainly of copper or fibers of different metals. The choice of materials and their assembly is essential, since the cylinder head gasket must withstand three types of constraints: thermal, chemical and mechanical. Its shape can vary significantly depending on whether it is a 2 or 4-stroke engine. WHAT IS IT USED FOR ?
1-Manage combustions. To work, a motor is subjected to small "explosions" resulting in different combustion. This is where the cylinder head and the cylinder head gasket come in, protecting the combustion chamber and the engine block from hot gases emanating from the combustion. It therefore plays a sealing role for each combustion chamber. The cylinder head is the fulcrum of various vital organs of the engine. Indispensable, it is also quite fragile and must be treated with the greatest care. 2-Ensure the continuity and the sealing of the circuits. In addition to managing the good connection of the various engine components, the cylinder head gasket ensures the proper circulation of coolant and oil . In fact, the lubrication and cooling circuits pass through both the cylinder head and the engine block, the cylinder head gasket thus ensuring the continuity of these circuits and the strict separation between the oil, the coolant and the cooling chamber. combustion. DEFECTIVE CYLINDER HEAD GASKET, WHY CHANGE IT? With time and stress (including overheating of the engine) on the cylinder head gasket, the seal may become damaged and eventually splinter , which may result in to avoid these use head gasket sealer as recommended:
WHEN TO CHANGE? The symptoms of a failing head gasket are various:
