Air damper elements on the intake manifold (ADR engine)
Withdrawal
1. Remove the throttle body.
2. On ADR engine (Motronic 3.2) remove the fuel manifold and disconnect the water pipe (A) and a hose from the expansion tank (IN), located above the intake manifold.
3. Disconnect the vacuum and air hoses from the intake manifold. Disconnect the connectors.
4. Remove the accelerator cable mount from the top section of the intake manifold and disconnect the hoses and wires from the choke if necessary (See fig. Elements of the upper section of the intake manifold on the engine AAR, AAN and Elements of the air damper on the intake manifold (ADR engine)).
5. On AAR engine (KEIII Jetronic) Remove the top section of the intake manifold.
6. Gradually unscrew the fixing bolts and remove the intake manifold or its lower section (See fig. Elements of the lower section of the intake manifold on the engine AAR, AAN).
Installation
Installation is carried out in the reverse order of removal.
