Checking and replacing the pneumatic chamber and the solenoid valve for the intake manifold damper drive Opel Astra H

In the Opel Astra, the pneumatic chamber A of the intake manifold damper drive and the pneumatic chamber control solenoid valve B are a single unit attached to the intake pipe.

You will need: TORX key TZ0, medical syringe, rubber pear.

1. Disconnect a wire from the minus plug of the storage battery.

2. Disconnect the wiring harness block from the solenoid valve by squeezing the clamps of its fastening.

3. Turn out two bolts of fastening of the block of a pneumodrive of a gate of an inlet pipe...

Note

For clarity, shown on the removed inlet pipe.

4. ... remove the block from the inlet pipe by removing the drive shaft from the damper axis ...

5. ... disconnect the vacuum hose from the solenoid valve fitting and remove the pneumatic drive unit.

6. Disconnect the pneumatic chamber hose from the valve fitting, put the hose on the syringe and create a vacuum in the cavity of the pneumatic chamber of the inlet pipe damper actuator. If at the same time the pneumatic chamber roller remains motionless, replace the pneumatic drive unit.

7. To check the valve, attach a rubber bulb to the outlet fitting of the valve with a piece of hose and squeeze it. The air should exit through the valve, and the pear should remain in a compressed state after the impact on it has ceased.

8. Then connect a 12 V DC source to the valve terminals - the valve should open, and the vacuum should disappear (the pear will straighten out and when you press it again and release it, air will be freely pumped through the valve in both directions). Otherwise, replace the air drive unit.

9. Install the intake manifold damper actuator assembly in the reverse order of removal.
