Master Cylinder

The Clutch Master Cylinder service process begins by disconnecting the vehicle's negative Battery Cable. Begin the Clutch Master Cylinder service by first removing the three components: lh i/p lower insulator panel, Clutch Master Cylinder rod retainer and Clutch Master Cylinder rod. These components are located on the clutch pedal. Proceed by removing the windshield washer solvent container afterward raise and properly support the vehicle. Remove the clutch actuator cylinder hose by pulling it from the hose retaining clip located at the engine's back end. The hydraulic clutch line separator (J 36221) enables users to disconnect the master cylinder hose by depressing its white circular release ring while pulling gently on the line while maintenance personnel take care to shield both hose ends from contaminants and scraping. Lower the vehicle off its hoist while it remains in place before taking out the Clutch Master Cylinder reservoir push-in fasteners. First rotate the Clutch Master Cylinder a 45-degree anti-clockwise turn to dislodge it from the dash panel before extracting it out of the vehicle. Position the Clutch Master Cylinder and reservoir before orientating the master cylinder at a 45-degree angle when you should insert it into the dash panel while rotating clockwise to secure it without exceeding the proper rotation angle. Start by reinstalling the Clutch Master Cylinder reservoir followed by reattaching its push-in fasteners followed by reinstalling the windshield washer solvent container. Reposition the vehicle keeping the clutch actuator cylinder hose next to the master cylinder hose before carefully joining both components using their quick connect fittings. First inspect the clutch hydraulic hoses for kinks and twists and afterward route the clutch actuator cylinder hose to the hose retaining clip near the engine's back end. After placing the vehicle in its proper position, fasten the Clutch Master Cylinder rod to the clutch pedal by using the rod retainer. The lh i/p lower insulator panel returns to its place before you attach the negative Battery Cable with a bolt tightness set to 15 nm (11 ft. Lbs.). The last steps involve transmitter programming then hydraulic clutch bleeding.

Raise the vehicle again and connect the clutch actuator cylinder hose to the clutch master cylinder hose, ensuring the quick connect fittings are securely engaged.

Position the clutch master cylinder and reservoir, orientate the master cylinder at a 45-degree angle, and insert it into the dash panel, rotating it clockwise to secure without over-rotating.
