VACUUM DAMPER, INSTALLING

- Disconnect ignition coil connectors -1-, -2- and -3-




- Remove mounting screws for ignition coils (arrows)




- Snap vacuum damper -7- into vacuum damper mounting bracket -8- and attach to bracket via self-tapping screw

- Attach fabric hose -1- onto vacuum damper

Note
Before installing this assembly, the vacuum hose below the intake manifold must be routed towards the rear.




- install vacuum damper assembly with vacuum hose attached

- Reconnect the ignition coils

Note
The vacuum supply line for the EVAP canister purge solenoid valve is connected to the power brake servo check valve.

- Connect the vacuum supply lines in the direction of the solenoid valve

VEHICLES WITH EGR:




- Remove the vacuum line to the change-over valve solenoid -B- behind branch -A-

VEHICLES WITHOUT EGR:

- Disconnect the vacuum line from the manifold change-over valve solenoid

- First, connect the vacuum lines to items -10-, -11-, -12-, -13- and -15-

Note
Ensure that the check valve is correctly installed; the blue connection faces the Y connector which the vacuum line to the vacuum damper is attached to.




- Attach the previously assembled vacuum hose to. branch -A-, note that branch -A-is not installed on vehicles without EGR




- Attach vacuum hose -14- to EVAP canister hose using tie wrap

VEHICLES WITH MANUAL TRANSMISSION ONLY:

- Install air guide hose between Mass Air Flow sensor and intake manifold

- Compare installation with vacuum diagram to ensure that the routing is correct
