EBCV Procedure

Begin With This Procedure If Original Campaign 88C30 Was Not Previously Performed.

1. Remove air cleaner housing:





a. Remove bolt and nut (Figure 2, 1).

b. Disconnect the following hoses:

- AS (Air Suction) hose (Figure 2, 5)
- HAI (Hot Air Intake) hose ((Figure 2, 3)
- PCV (Positive Crankcase Ventilation) hose (Figure 2, 4)
- HIC (Hot Idle Compensator) hose (Figure 2, 2)

c. Remove air cleaner housing.





2. Loosen and remove vacuum hose tie strap (Figure 3, 2). Be certain to note which hoses are retained by tie strap so proper hoses can be regathered when tie strap is reinstalled in step 20.

3. Disconnect, at 6-way vacuum tee, the two (2) vacuum hoses running from EBCV to 6-way vacuum tee.

4. Disconnect and remove 2 vacuum hoses (Figure 3, 3) which run from 6-way connector to carburetor. These hoses will not be reused.

5. Remove 6-way connector. This connector will be replaced with two 3-way connectors supplied in kit.





6. Disconnect EBCV electrical connector (Figure 4, 3) and vacuum switch electrical connector (Figure 4, 2).





7. Remove two (2) bolts attaching EBCV bracket to strut tower and fender (Figure 5).

8. Remove EBCV--Wire harness from EBCV bracket clamp (Figure 4, 1).

9. Remove EBCV from EBCV bracket by removing securing bolt and nut (EBCV should still have two (2) vacuum hoses attached). See Figure 5.

10. Remove two (2) vacuum hoses still attached to EBCV and install hoses on new EBCV from kit.

11. Install new EBCV into EBCV bracket with securing bolt and nut (Figure 5).





NOTICE:
Seat EBCV into claw on EBCV bracket (Figure 6).

12. Reinstall EBCV bracket to strut tower with 2 bolts (Figure 5).





13. For Manual Transmission equipped vehicles, connect new red 3-way connector to end of vacuum hose from EBCV port M. Connect new blue 3-way connector to end of vacuum hose from EBCV port S (Figure 7).

For Automatic Transmission equipped vehicles, connect new brown 3-way connector to end of vacuum hose from EBCV port M. Connect new white 3-way connector to end of vacuum hose from EBCV port S (Figure 7).





14. Connect vacuum hose from EBCV port M to vacuum hose from A port of HAC (High Altitude Compensation) valve. Be certain to connect vacuum hose from HAC to center outlet of 3-way connector (Figures 7 and 8).

15. Connect vacuum hose from S port of EBCV to vacuum hose from B port of HAC. Be certain to connect vacuum hose from HAC to center outlet of 3-way connector (Figure 7 and 8).

16. Install one end of new 480 mm vacuum hose to remaining outlet of 3-way connector from EBCV M port (Figure 7).





17. Connect remaining end of 480 mm vacuum hose to Primary main Air Bleed Port of carburetor (Figure 7, 8 and 9).

18. Connect one end of new 510 mm vacuum hose to remaining outlet of 3-way connector from EBCV S port (Figure 7).





19. Connect remaining end of 510 mm vacuum hose to Slow Air Bleed Port of carburetor (Figure 7 and 10).

20. Reinstall vacuum hose tie strap being certain to gather all hoses previously retained by tie strap.





21. Reconnect EBCV wiring harness to EBCV bracket clamp (Figure 4, 1).

22. Reconnect EBCV electrical connector (Figure 4, 3) and vacuum switch electrical connector (Figure 4, 2).





23. Check hose connections in locations shown in Figure 11.

24. Reinstall air cleaner housing.





a. Connecting the following hoses:
- HIC hose (Figure 2, 2) - PCV hose (Figure 2, 4)
- HAI hose (Figure 2, 3) - AS hose (Figure 2, 5)

b. Reinstall air cleaner housing with bolt and nut (Figure 2, 1).
