  4. Remove the cap from the nipple (1) on top of the clutch slave cylinder union (4).
    NOTE:

    Do not allow clutch/brake fluid reservoir to run dry while bleeding the clutch. If the reservoir runs dry during this procedure, It must be refilled and the process must be repeated  .

  5. Have a helper depress and hold the clutch pedal to the floor.
    NOTE:

    Verify the helper understands not release the clutch pedal from the floor until the technician closes the bleed port and signals the helper to cycle the clutch pedal to avoid inadvertently drawing air back into the system.

  6. Connect a length of transparent tubing (1) to the bleeder nipple on the slave cylinder union. Insert the lower end of the transparent tube (1) into a clean container to catch the flow (4).
  7. 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.
  8. Push the line (3) inward until the clip (2) snaps in place to stop the bleeder flow.
  9. Repeat steps 5 through 8 at least fifteen times or until air bubbles are no longer visible in the transparent tube (1).
  10. Slowly actuate the clutch pedal ten up/down cycles.
  11. Apply the 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 within the system, most likely at the master cylinder.

  12. Remove the transparent tube (1) from the nipple on the slave cylinder union.
  13. Install the belly pan, if removed.
  14. Lower the vehicle.
  15. Top off brake master cylinder fluid level with DOT 3 brake fluid as necessary.
