To remove the clutch master cylinder, first disconnect the cable from the negative battery terminal, ensuring you have the correct activation code for the radio if it has an anti-theft system. Next, work under the dashboard to remove the cotter pin or spring clip from the master cylinder pushrod clevis and pull out the clevis pin to disconnect the pushrod from the pedal. Detach the clutch master cylinder reservoir, which is located in the left rear corner of the engine compartment, by removing the two bolts and lifting it out of the way. Use locking pliers to clamp the clutch fluid feed hose a couple of inches downstream of the reservoir to prevent fluid from leaking when disconnecting it from the clutch master cylinder. Disconnect the hydraulic lines at the cylinder by loosening the hose clamp on the feed line and using a flare-nut wrench to loosen the pressure line fitting, then remove the two mounting bolts from under the dash. Loosen the fluid feed hose clamp and detach the hose from the cylinder, having rags ready to catch any fluid that may spill. Cap or plug the ends of the lines to prevent leakage and contamination, taking care to avoid brake fluid contact with paint. Finally, unscrew the two retaining nuts for the clutch master cylinder, remove the cotter pin and clevis pin to detach it from the pedal, and take the cylinder out. For installation, position the master cylinder and install the mounting nuts finger tight. Connect the hydraulic lines to the master cylinder, adjusting the cylinder as needed to thread the fitting, and attach the fluid feed hose, tightening the hose clamp. Securely tighten the mounting nuts and the hydraulic line fitting, then connect the pushrod to the clutch pedal, using a new cotter pin if necessary. Remove the locking pliers from the feed hose, fill the clutch master cylinder reservoir with brake fluid that meets DOT 3 specifications, and bleed the clutch system.
