To remove the clutch master cylinder, firstly disconnect the cable from the negative battery terminal. In the passenger compartment, remove the driver's side under cover at the dashboard, remove the clip retaining the clutch master cylinder pushrod to the clutch pedal and slide the pushrod off the clutch pedal pin, checking the plastic retainer for damage and replacing it if necessary. Remove the mounting nut(s) for the clutch master cylinder from below the dash at the firewall. On 1998 and older models, note only one nut is accessible from here. In the engine compartment, disconnect the hydraulic line from the clutch master cylinder using a flare-nut wrench, if available. Next, unfasten the nut(s) that attach the clutch master cylinder and fluid reservoir to the firewall. Take care to remove the clutch master cylinder and reservoir from the engine bay without damaging the hydraulic line. For installation, install the pushrod of the clutch master cylinder through the firewall and finger-tight fasteners. Attach a new clip after joining the master cylinder pushrod with the clutch pedal pin inside the car, and also connect the master cylinder hydraulic line with the master cylinder. Reposition every component you removed and tighten the mounting fasteners. To finish, bleed the hydraulic clutch system and wash off any spills with water; do not let paint come into contact with brake fluid as it damages paint.
