Disconnect the negative battery cable.
Remove lower filler panel from under the dash.
If necessary, remove the lower left A/C duct.

To expedite the hydraulic clutch bleeding, lose as little fluid as possible when disconnecting hydraulic lines. All openings should be immediately capped or plugged to prevent system contamination or excessive fluid loss.

Detach the hydraulic clutch quick-connect from the concentric slave cylinder following 1 of the 2 steps: A. Use 2 small prytools at 180 degrees from each other to depress the white plastic sleeve on the quick connect to separate the clutch line from the concentric slave cylinder quick connect.

B. Use special tool J-36221 to depress the white plastic sleeve on the quick connect to separate the clutch line end from the concentric slave cylinder quick connect.

Disconnect the tubes clips from the wiring harness bracket and sheet metal.
Remove the master cylinder from the cowl panel by grasping the cylinder body and rotating it about 45 degrees clockwise, then withdrawing it from the opening.

To install: Hold the master cylinder assembly at a 45 degree angle (as during removal), then install the master cylinder to the cowl by inserting and twisting counterclockwise 45 degrees. Be sure not to over rotate the cylinder assembly or damage will occur.
Connect the clutch line to the slave cylinder. On some 4.3L models, a special band tie is used to attach the tubing to the body.
Connect the tubes clips to the wiring harness bracket and sheet metal.
Connect the pushrod to the pedal and secure using the retainer.
If removed, install the lower left A/C duct.
Install the lower filler panel.
Connect the negative battery cable.
Properly refill the master cylinder reservoir, then bleed the system of air and check for fluid leaks.
