Clutch hydraulic system — bleeding

1. The hydraulic system should be bled of all air whenever any part of the system has been removed or if the fluid level has been allowed to fall so low that air has been drawn into the master cylinder. The procedure is very similar to bleeding a brake system.

2. Fill the master cylinder with new brake fluid conforming to DOT 3 specifications.

Cau tion: Do not re-use any of the fluid coming from the system during the bleeding operation or use fluid which has been inside an open container for an extended period of time.

3. Remove the air filter housing and fresh air inlet duct (see Fuel and exhaust systems).

4. Remove the dust cap that fits over the bleeder valve and push a length of plastic hose over the valve.

Note: On 2009 and earlier models, the bleeder valve is located on the clutch release cylinder. On 2010 and later models, the bleeder valve is located on the junction block between the tube leading from the clutch orifice assembly and the tube that goes into the bell-housing (to the clutch release cylinder). Place the other end of the hose into a clear container with about two inches of brake fluid in it. The hose end must be submerged in the fluid.

5. Have an assistant depress the clutch pedal and hold it. Open the bleeder valve, allowing fluid to flow through the hose. Close the bleeder valve when fluid stops flowing from the hose. Once closed, have your assistant release the pedal.

6. Continue this process until all air is evacuated from the system, indicated by a full, solid stream of fluid being ejected from the bleeder valve each time and no air bubbles in the hose or container. Keep a close watch on the fluid level inside the clutch master cylinder reservoir; if the level drops too low, air will be sucked back into the system and the process will have to be started all over again.

7. Check carefully for proper operation before placing the vehicle in normal service.
