Note: It is not necessary to remove the engine to remove the cylinder head.
Attention.
- To prevent damage to the paintwork of the body wings, it is necessary to use a special coating.
- To prevent damage to the cylinder head, wait until the engine has cooled down before removing it.
- When removing the metal cylinder head gasket, be careful not to drop it or damage the contact surface of the block to the head.
- When disconnecting wiring, apply force directly to the connector, not to the wire.
Note: To avoid incorrect connections, it is necessary to label all wires and hoses.
