Recommendation. The work is laborious. In addition, some operations are hindered by the tight arrangement in the engine compartment. Access to the front mounting of the intake module can be improved by installing a rolling jack under the engine and removing the left and rear power unit supports. When performing work, you can move the engine to a more convenient position, opening up more convenient access to the fasteners.
To perform the work, an inspection ditch or overpass is required.
Removing
1. We prepare the car for work and install it on a viewing ditch or overpass (see «Preparing the car for maintenance and repair»).
2. Disconnect the wire terminal from the negative terminal of the battery (see «Battery - removal and installation»).
3. Relieve fuel pressure (see «Fuel Line - Pressure Relief»), remove the fuel tube holder from the intake module and move the tube to the side.
4. Disconnect the wiring harness pads from the ignition coils (see «Ignition coil - check and replacement») and take the harness to the side.
5. Disconnect the wiring harness block from the camshaft position sensor (see «Camshaft Position Sensor - Check and Replace») and take the harness to the side.
6. Disconnect the pads of the wiring harnesses from the solenoid valve of the system for changing the length of the inlet pipeline, as well as the connecting pads (see «The solenoid valve for the intake manifold length change system - check and replace» And «Fuel rail - removal and installation»).
7. After loosening the clamp, remove the hose of the vacuum brake booster from the branch pipe of the inlet module.
8. Remove the air filter intake (see «Air filter - removal and installation») and remove the air supply hose from the nozzle of the throttle assembly (see «Throttle assembly - removal, gasket replacement and installation»).
9. Remove the engine mudguard.
10. Loosen the clamp that secures the hose of the crankcase ventilation system and remove the hose from the pipe of the cylinder head.
11. Using a short Phillips screwdriver, unscrew the self-tapping screw 1 for fastening the guide tube of the oil level indicator.
12. We take out the guide tube together with the oil level indicator from the engine block and remove it.
13. Using a 10 mm wrench, unscrew the two nuts securing the intake module to the cylinder head cover and three bolts securing the ignition coils of the first, second and third cylinders.
14. Remove the ignition coils of the first, second and third cylinders (see «Ignition coil - check and replacement»).
15. Using a 13 mm socket wrench, unscrew the three nuts and two bolts securing the intake module to the side surface of the engine cylinder head.
16. Disconnect the additional muffler from the exhaust pipe (see «Additional muffler - replacement»).
17. We substitute a support under the engine and disconnect the rear support of the power unit from the body (see «Power unit mounts - replacement»).
18. We reject the engine back.
19. Remove the intake module from the engine.
20. We remove the rubber sealing rings from the grooves of the inlet module flange.
Installation
Install the intake module in reverse order. We replace damaged sealing rings of the inlet module.
