Power Bleeding Clutch Hydraulic Circuit

WARNING: This page is about a different variant/trim than selected.
  1. Remove reservoir cap and connect bleeder cap to clutch/brake fluid reservoir.
    NOTE:

    Use Bleeder Cap/Modified reservoir cap adapter Snap-on #901-059 or equivalent.

  2. Connect power bleeding machine to bleeder cap.
    NOTE:

    Use Service Filling Machine/Brake power bleeder or equivalent.

  3. Service filling machine should be pressurized between 2.0 and 2.5 bar (29 - 36 PSI).
  4. Raise vehicle on a suitable hoist.
  5. Remove the belly pan, if equipped.

  7. Connect a length of transparent tubing (1) to the bleeder nipple. Insert the open end of the transparent tube (1) into a clean container to catch the fluid flow (4) during bleeding procedure.
  8. Turn ON the power bleeding machine.
    NOTE:

    While bleeding the system, do not allow the clutch fluid reservoir to completely to run dry. If this happens, refill the clutch fluid reservoir, and repeat the procedure.

  9. Press downward on the retainer clip (2) holding the hydraulic line to the slave cylinder union while pulling outward on the hydraulic hose (3) to open the bleeder flow (4). This allows the line to pop out about 1/8 in (3 mm) which opens the bleeder. Any air in the system will escape at this time.
  10. Allow fluid to flow (4) out of bleed port until no air bubbles are visible in the transparent tube (1).
  11. Push the line (3) inward until the clip (2) snaps in place to stop the bleeder flow.
  12. If necessary, lower the vehicle.
  13. Slowly actuate the clutch pedal fifteen up/down cycles.
  14. If necessary, hoist the vehicle.
  15. Repeat steps 9 through 11 to verify air is NOT trapped in the system.
  16. Turn OFF power bleeder machine.
  17. If necessary, lower the vehicle.
  18. Apply brakes 

    Start engine and verify clutch operation and pedal feel. If the clutch pedal feels fine and the transaxle can be easily shifted from neutral to any gear, the clutch is operating correctly. If pedal still feels spongy or clutch does not fully disengage, excessive air is still trapped in the system.

  19. If clutch function is normal, disconnect bleeder machine and install reservoir cap.
  20. If necessary, hoist the vehicle.
  21. Remove the transparent tube (1) from the nipple on the slave cylinder union and install the dust cover.
  22. Install the belly pan, if removed.
  23. Lower the vehicle.
