Clutch Hydraulic System: Service and Repair

Hydraulic Clutch System Bleeding

Special Tools

* J-35555 - Metal Mityvac

* J 43485 - Power Steering Bleeder Adapter

Caution:
DO NOT use fluid which has been bled from a hydraulic clutch system, in order to fill the clutch master cylinder reservoir, due to the possibility that the fluid may be aerated, have too much moisture content, or be contaminated and may cause system or vehicle damage.

1. Clutch pedal must be in the full up position to properly bleed the system.

2. Verify that all the lines and fittings are dry and secure.

3. Clean the dirt and grease from the reservoir cap in order to ensure that no foreign substances enter the system.

4. Remove the reservoir cap.

5. Fill the reservoir to the proper level with the required fluid.
Some manual transmission equipped vehicles have a combined brake and clutch fluid reservoir.

6. Attach the J 43485 - power steering bleeder adapter to the J-35555 - Metal Mityvac, or equivalent.

Note: Brake fluid will deteriorate the rubber on the J 43485 - power steering bleeder adapter. Use a clean shop cloth to wipe away the fluid after each use.

7. Place and hold the adapter on the reservoir filler neck to ensure a tight fit. In some cases, the adapter will fit into the reservoir opening.

8. Apply a vacuum of 51-68 kPa (15-20 Hg) and remove the adapter.

9. Refill the reservoir to the proper level.

10. Repeat steps 6 and 7.

11. If needed, refill the reservoir and continue to pull a vacuum until no more bubbles can be seen in the reservoir or until the fluid level no longer drops.

Warning

The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear.

12. Pump the clutch pedal until firm (to refill actuator cylinder).

13. Add additional fluid if needed.

14. Test drive the vehicle to ensure proper operation.
