Cylinder head for Hyundai D4BA

The cylinder head, part number 221004A025, mounts to the top of the engine block in Hyundai machinery equipped with D4BA, D4CB LEVAS, and D4EA engines. This component seals the cylinders to form the combustion chambers where air and fuel ignite to produce power. It houses the intake and exhaust valves, provides passages for gas flow, and includes ports for injectors and glow plugs. The casting also features internal channels for coolant circulation to manage thermal loads and oil galleries to lubricate the valve train assembly.

This component is compatible with Hyundai D4BA, D4CB LEVAS, and D4EA engine models. It is engineered to maintain the structural integrity required for the pressures and temperatures of the combustion cycle. A properly functioning cylinder head is necessary to maintain compression, engine output, and emission control. Regular inspection of the head surface and valve seats helps prevent loss of compression or overheating issues within the engine system.
