With Bleeder Screw

1991 Oldsmobile Toronado V6-3800 3.8LSECTION With Bleeder Screw

SYSTEM BLEEDING
1. Clean dirt and grease from the cap to ensure no foreign substances enter the system.

2. Remove cap and diaphragm and fill reservoir to the top with hydraulic clutch fluid No. 12345347 or an equivalent fluid that meets DOT 3 specifications.

3. Loosen bleed screw which is located on the slave cylinder body next to the inlet connection.

4. Fluid will now begin to move from the master cylinder down the tube to the slave. For efficient gravity fill, the reservoir must be kept full at all times.

5. It will be noticeable at this point, that bubbles will appear at the bleed screw outlet. This means that air is being expelled from the system. When the slave is full, a steady stream of fluid will come from the slave outlet. At this point, tighten bleed screw.

6. Assemble diaphragm and cap to the reservoir. Fluid in reservoir should be level with step.

7. The hydraulic system should now be fully bled and should release the clutch. Check vehicle by starting the engine, pushing clutch pedal to the floor and selecting reverse gear. There should be no grating of gears. If there is, the hydraulic system still contains air. If this is the case, repeat bleed procedure.
