not available separately. Bleeding the system should not be attempted and is not recommended.
REMOVAL

2. Remove the two bolts attaching the master cylinder to the firewall.

4. Remove the master cylinder from the opening in the firewall and remove the hydraulic system assembly upward from the engine compartment.
5. Remove the clutch housing.
INSTALLATION

below the steering column shaft.

3. Insert the master cylinder push rod through the opening in the firewall, position the master cylinder on the firewall, and install the attaching bolts.
Tighten to 21-27 Nm (15-20 ft lbs).
4. Clean and apply a light film of SAE 30 oil to the master cylinder push rod bushing. Install the bushing and push rod to the clutch pedal. Retain

5. Check the clutch reservoir and add fluid, if required. Depress the clutch pedal at least 10 times to verify smooth operation and proper clutch
release.

that is displaced from the slave cylinder as the clutch wears.
