DESCRIPTION
The cylinder head is a crucial component of the engine. It sits on top of the cylinder block and forms the combustion chamber where fuel and air mix and ignite, creating power to move the vehicle. The 4987978NX cylinder head is a specific part number used in certain truck models. It is designed to fit perfectly with the corresponding engine, ensuring proper compression ratios and efficient combustion. The cylinder head must be made from durable materials such as aluminum or cast iron, as it undergoes extreme temperature changes during operation. It also contains various ports for fuel injection, coolant circulation, and exhaust gas recirculation (EGR) systems. Proper maintenance of the cylinder head includes regular inspections for cracks or warping, as well as replacing worn gaskets to prevent oil leaks or loss of compression.
