Fluid Level

1. If clutch slave cylinder travel does not meet the travel requirements, check the clutch master cylinder reservoir fluid level. The proper level is indicated by a step on the reservoir.

2.  CAUTION: Carefully clean the top and sides of the reservoir before opening to prevent contamination of the system with dirt, water and other foreign material. Remove the reservoir diaphragm when checking or adding fluid. Carefully replace the diaphragm, cover gasket and cover after filling.

   Fill to the specified level with High Performance DOT 3 Brake Fluid C6AZ-19542-AA or equivalent DOT 3 fluid meeting Ford specification ESA-M6C25-A. Do not overfill. The upper portion of the reservoir must accept fluid that is displaced from the clutch slave cylinder as the clutch wears.

3. If the clutch master cylinder reservoir requires any fluid, check the hydraulic system components for leakage.

4. Inspect the clutch master cylinder (7A543) from the driver's side of the dash.

5. Check all tube connections. A slight wetting of the surfaces is acceptable.

6. Replace the component if excessive leakage is evident. The clutch slave cylinder can be inspected for leakage by removing the inspection plug in the clutch housing portion of case.

7. If the proper amount of fluid is found in the clutch master cylinder reservoir and no leaks are found, air may be present in the clutch hydraulic system. The clutch hydraulic system must be bled. Refer to appropriate clutch hydraulic system bleeding procedure in the Adjustments portion of this section.

   The fluid level in the clutch master cylinder reservoir will slowly increase or rise as the clutch disc wears. As long as the fluid level is visible at or above the stop in the translucent reservoir body, top-off is not necessary and should not be done, to prevent overflow and possible contamination of the fluid while it is exposed.
