Remove the interior panels as needed to access the clutch master cylinder.
Disconnect the hydraulic lines from the clutch master cylinder.
Unbolt and remove the clutch master cylinder from the firewall.
Install the new clutch master cylinder and reconnect hydraulic lines.
Repeat the process for the slave cylinder located on the transmission.
