Manual Bleeding Clutch Hydraulic Circuit

WARNING: This page is about a different variant/trim than selected.
NOTE:

An assistant is required to perform this procedure.

  1. Verify fluid level in clutch/brake cylinder. Top off with DOT 3 brake fluid as necessary. Leave cap off.
    NOTE:

    The container must be positioned at a lower level than the bleeder valve on the clutch slave cylinder

  2. Install suitable size and length of clear hose to the bleeder port (1) in order to monitor and divert fluid into a suitable container.
  3. Have the assistant press down and hold the clutch pedal until it reaches the floor.
    NOTE:

    Do not allow clutch/brake fluid reservoir to run dry while fluid exits bleed port. If the reservoir runs dry during this procedure, it must be refilled. and this step must be repeated.

    NOTE:

    Ensure the assistant does not release the clutch pedal from the floor while the bleed port on the clutch slave cylinder is open. Otherwise, air will enter the clutch hydraulic circuit.

  4. Open the bleed port on the clutch slave cylinder enough to allow hydraulic fluid to drain. Any air in the system will escape at this time.
  5. Close the bleed port on the clutch slave cylinder, and have the assistant release the clutch pedal to the full up position.
  6. Repeat steps 3 through 5 at least 15 times or until air bubbles are no longer present in the clutch hydraulic fluid.
  7. Slowly actuate the clutch pedal 10 times between the full up and pedal stop position.
  8. Apply parking brake  . 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.
  9. Disconnect the hose from the bleed port on the clutch slave cylinder.
  10. Top off brake master cylinder fluid level with DOT 3 brake fluid as necessary.
