To carry out the work, you will need an inspection pit or overpass.
Removal
1. Remove the throttle assembly (see "Throttle assembly - removal, gasket replacement and installation") and release the fuel pressure (see "Fuel Line - Pressure Relief").
Tip: The throttle body can be removed without disconnecting the hoses. It is enough to disconnect it from the intake module flange.
2. Disconnect the throttle actuator cable from the intake module (see "Throttle Cable Replacement").
3. Disconnect the wiring harness connectors from the ignition coils (see "Ignition Coil - Checking and Replacing") and move the tourniquet to the side.
4. Disconnect the wiring harness connector from the camshaft position sensor (see "Camshaft Position Sensor - Removal, Checking and Installation") and move the tourniquet to the side.
5. After loosening the clamp, remove the brake booster hose from the intake module pipe.
6. Remove the air filter air intake (see "Air filter - removal and installation").
7. Using an 8 mm wrench, loosen the clamp securing the engine crankcase ventilation hose and remove the hose from the cylinder head cover pipe.
8. Using a short Phillips screwdriver, unscrew screw 1 securing the oil level indicator guide tube.
9. Remove the guide tube together with the oil level indicator from the engine cylinder block and remove it.
10. Using a 10 mm wrench, unscrew the two nuts 1 securing the intake module to the cylinder head cover and the three bolts 2 securing the ignition coils of the first, second and third cylinders.
11. Remove the ignition coils of the first, second and third cylinders (see "Ignition Coil - Checking and Replacing").
12. Remove the engine splash guard or crankcase protection (if installed).
13. Using a 13 mm socket wrench, unscrew the three nuts 2 and two bolts 1 securing the intake module to the side surface of the engine cylinder head.
14. Having moved the intake module forward, remove the fuel rail (see "Fuel rail - removal and installation").
15. Remove the intake module from the engine.
Installation
We install the intake module in the reverse order. We replace damaged sealing rings of the intake module.
