Section B

Section B: The procedure below outlines the installation of a VANOS accumulator shutoff valve (mechanical components only) on M5 and Z8 vehicles produced from 9/1/00 up to 11/30/00.





Parts kit part number 11 36 7 832 858 includes as shown.

1. If not already removed (repairs performed in Section A), remove the air intake duct (intake air silencer upper section, air mass meter, bellows) for cylinder bank 2.

2. Remove the radiator fan/clutch assembly. See repair manual group 11, section 11 52 020.

3. Remove the main fan belt. See repair manual group 11, section 11 28 010.

4. Remove the front engine lifting eye bracket.





5. Disconnect plug (1) and remove the wire harness plug housing from the bracket.

6. Disconnect plug (2) and unclip the corrugated tubing for this wire at the VANOS accumulator bracket.

7. Remove the VANOS accumulator with connecting hose (to the oil distributor) and bracket.

Important
The hollow bolt (PN 11 36 1 407 716) used to secure the hose to the oil distributor and both M6 x 25 hex bolts with washers (PN 07 11 9 900 249) used to secure the accumulator bracket to the timing case cover are still needed. Do not discard.





8. Pre-fit the hex bolt with washer (7) to bracket (6). Only hand tighten the bolt so that the new VANOS accumulator (1) can be easily pushed into the bracket (6). Install clip (8) on bracket (6).

9. Attach the bracket (6) to the timing case cover using the two M6 x 25 hex bolts. Hand tighten bolts only.

10. Pre-fit connecting hose (4) to the VANOS accumulator (1) using hollow bolt (3) and two seal washers (2). Hand tighten bolt only.

11. Slide the new VANOS accumulator (1) into bracket (3). Slide accumulator in up to stop on bracket.





12. Pre-fit the connecting hose to the oil distributor (5) using hollow bolt (4) and two seal washers. Hand tighten bolt only.

13. Position all installed components and tighten all bolts.

Torque specifications:

Hollow bolt M12 for connecting hose to oil distributor = 20 Nm (14.7 lb.ft.)

Hollow bolt M10 for connecting hose to VANOS accumulator = 13 Nm (9.6 lb.ft.)

M6 hex bolts for bracket to timing case cover = 10 Nm (7.4 lb.ft.)





14. Plug connector (2) onto VANOS accumulator shutoff valve.

15. Plug in connector (6). Clip corrugated tubing for this wire onto the VANOS accumulator bracket clip.

16. Lock connector housing into support and plug in connector (7).

17. Reinstall the front engine lifting eye bracket.

18. Reinstall the main fan belt.

19. Reinstall the radiator fan/clutch assembly.

20. Reinstall the air intake duct (intake air silencer upper section, air mass meter, bellows) for cylinder bank 2.
