Removal and installation air intake tract components (Opel Corsa C)

Removal

1. The general connection diagram of the air supply system intake tract components is shown in the accompanying illustrations. Basically, the fastening of pipelines and hoses is carried out using clamps of various types. In some cases, bolted connections are used for this purpose.

6.1a. Air intake tract (using the Z12XE engine as an example): 1. Air purifier; 2. Air mass measurement sensor; 3. Air intake duct; 4. Inlet unit; 5. Crankcase ventilation hose; 6. Air intake of the air supply system with a resonator; 7. Connecting sleeve

6.1b. Components of the air intake tract of a turbocharged diesel engine (using the Z17DT engine as an example): 1. Air cleaner housing; 2. Air mass measurement sensor; 3. Air intake duct; 4. Inlet pipe; 5. Throttle valve inlet pipe; 6, 7, 9. Boost hoses; 8. Intercooler (intercooler); 10, 11. Boost pipes; 12. Air intake with resonator; 13. Connecting hose

2. The most important element of the air supply system is the air cleaner. When performing maintenance work, it is sufficient to remove only the top cover (see Chapter 1), but when performing many repairs and replacing other elements of the engine compartment, it is necessary to dismantle the entire air cleaner assembly.

3. This Section provides a detailed description of the procedure for removing the air cleaner on the Z13DT engine. On other engines, this operation is performed similarly.

4. Press the lock in the direction indicated by the arrow (see accompanying illustration), disconnect the air mass sensor wiring connector. Release the wiring harness by cutting the holders, if necessary, mark their position for subsequent installation of new ones.

6.4. Air purifier (5) (using the Z13DT engine as an example): 1. Air mass sensor wiring connector; 2. Retainer; 3. Fastening clamp; 4. Fastening screw Torg; 6. Air cleaner support; 7. Connecting hose

5. Using a socket wrench (for example, Hazet 426-7) loosen the mounting clamp (see illustration 6.4) and disconnect the air intake duct from the intake manifold.

6. Using a screwdriver (for example, Hazet 837-T30), unscrew the screw Torgx securing the air cleaner holder to the top of the shock absorber strut (see illustration 6.4)

7. Lift the air cleaner from the holder side and detach it from the support (see illustration 6.4) on the opposite side. Separate the connecting hose from the air cleaner and remove the cleaner assembly from the engine compartment.

Installation

8. Installation is performed in the reverse order of dismantling the components. When installing the connecting hose, make sure that the protrusion on the air cleaner housing pipe matches the groove on the hose.
