: It contains passages for coolant to flow through, absorbing heat to prevent the metal from warping or melting. Key Components Inside : It provides a mounting point for fuel

Because the cylinder head deals with high heat and pressure, it is susceptible to several problems: Cylinder Head Failure Analysis: Warped or Pitted Heads cylinder head

: The internal tunnels through which air and exhaust travel.
