Notice: Do not reuse the fluid that has been bled from a system in order to fill the clutch master cylinder reservoir for the following reasons:

1. The fluid may be aerated
2. The fluid may be contaminated
3. The fluid may contain too much moisture

Important: Bleed the hydraulic system whenever any part of the system has been disconnected, or the level of fluid in the reservoir is so low that air has been drawn into the master cylinder.

1. Remove the PCM from the mounting bracket in order to access the clutch master cylinder for filling. Refer to Powertrain Control Module Replacement/Programming in Engine Controls.
2. Fill the master cylinder reservoir with clutch hydraulic fluid GM P/N 12345347, or equivalent.
3. In order to remove much of the air from the system prior to bleeding at the actuator, complete the following steps:

3.1.	Remove the clutch master cylinder cap and the moisture barrier.

3.2.	Reinstall the cap.

3.3.	Lightly stroke the clutch pedal in order to release air trapped in the system through the master cylinder.

3.4.	Remove the clutch master cylinder cap and reinstall the moisture barrier.

3.5.	Reinstall the cap.

4. Raise and support the vehicle. Refer to Section 0A.



5. Remove the actuator cylinder retaining nuts.



6. Remove the pushrod and the actuator cylinder from the clutch housing.
7. Remove the hydraulic line from the retaining clip.



8. Remove the bleed screw dust cap.
9. Hold the cylinder in a horizontal position with the bleeder screw vertical.
10. Fully depress the clutch pedal and open the bleed screw.
11. Close the bleed screw and release the clutch pedal.
12. Repeat steps 10 and 11 until all air is evacuated. Check and refill the clutch master cylinder reservoir as required in order to prevent air from being drawn through the clutch master cylinder.

1. Install the dust cap onto the bleed screw.



2. Install the hydraulic hose into the retaining clip.
3. Install the clutch actuator cylinder and the retaining nuts.

Tighten
Tighten the nuts to 25 N·m (18 lb ft).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Lower the vehicle.
5. Install the PCM. Refer to Powertrain Control Module Replacement/Programming in Engine Controls.
