Removing
1. Remove the ground wire from the battery. Unscrew screws and remove a plastic casing from the top part of a head of the block of cylinders.
2. On low pressure turbo engines, remove the metal and elastic pipe connecting the exhaust manifold to the turbocharger, and on high pressure turbo engines, remove the pipe connecting the manifold to the heat exchanger.
3. unscrew the screws (indicated by arrows) attaching the wiring harness bracket to the top of the intake manifold.
4. Disconnect the electrical connectors from the coolant sensors, high pressure fuel pump, crankshaft sensor, and manifold overpressure sensor, and move the harness bracket away from the manifold.
5. Remove the vacuum pipe from the EGR valve located on top of the manifold.
6. Unscrew the connecting nut that secures the fuel supply pipe to the injector.
7. Unscrew the union nut securing the fuel supply pipe to the fuel pump.
8. Remove the fuel supply pipes from the engine.
9. Evenly and gradually unscrew the bolts and remove the upper part of the manifold.
10. To remove the lower section of the intake manifold, disconnect the vacuum pipe from the diaphragm valve.
11. Remove the electrical connector bracket bolt.
12. Evenly and gradually unscrew the fastening nuts and remove the lower section of the manifold with the gasket from the cylinder head.
Installation
1. Install the lower section of the intake manifold along with the gasket on the cylinder head and secure with nuts by tightening them in a diagonal sequence.
2. Connect the diaphragm valve vacuum hose and install the electrical connector bracket.
3. Install the upper section of the intake manifold with the gasket and secure with bolts.
4. Install the fuel supply pipes from the fuel pump to the injectors.
5. Install the wiring harness bracket to the top of the manifold and secure with bolts.
6. Connect the electrical connectors and connect the vacuum pipe to the EGR valve.
7. Install the air intake duct and install the plastic shroud to the cylinder head.
8. Connect the battery, start the engine and check the fuel system for leaks.
