6. Disconnect the camshaft cover breather hose from the throttle body.
7. Disconnect the coolant hoses from the throttle body. Cap the open ends of the hoses to prevent further coolant loss.
8. Disconnect the wiring from the throttle position sensor.
9. Disconnect the vacuum line from the fuel pressure regulator.
10. Disconnect the wiring harness cover from the fuel injectors and move it to the side; be careful not to deform the wiring. Pull the housing, squeeze the fastening clips of the wiring connector to release the harness housing from the injectors.
11. Disconnect the fuel supply hoses from the fuel line. Plug the open ends of the hoses to prevent dirt from entering and causing further fuel leakage.
12. Unscrew and remove the upper nut and bolt securing the generator.
13. Make a final check to ensure all relevant hoses, pipes and wires are disconnected.
14. Unscrew the fastening nuts, remove the manifold from the cylinder head, remove the gasket (see illustrations).
15. It is possible that when unscrewing the fastening nuts from the cylinder head, the struts may come loose.
In this case, the struts must be screwed back into the head.
16. If required, the auxiliary components can be removed from the manifold in accordance with the relevant Section.
