Remove the clutch slave cylinder from the transmission, leaving it connected to the fluid line.

Perform these steps at the clutch master cylinder.

1) Loosen the nuts holding the clutch master cylinder to the firewall
2) Remove the clutch master cylinder reservoir cap and rubber diaphragm
3) Clean dirt and grease from the cap
4) Press in the clutch master cylinder pushrod approximately ¾” and HOLD IN PLACE.
5) While holding the clutch master cylinder pushrod in place, reinstall the reservoir cap and diaphragm.
6) Hold the slave cylinder vertically with its pushrod end facing down (air moving to the top of the slave cylinder). Keep the entire slave cylinder below the level of the clutch master cylinder.
7) Release the master cylinder pushrod
8) Press the SLAVE cylinder pushrod in slightly less than ½” using short strokes.
9) Look for air bubbles in the clutch master cylinder
10) Repeat steps 8 & 9 until you no longer see air bubbles.
11) Reinstall the slave cylinder on the transmission.
12) Tighten the master cylinder nuts to 15-ft/lbs

Push clutch to the floor and hold while starting engine. Wait 10-seconds. Select reverse gear with clutch still on floor. Gears should not grate. If they do, repeat the bleeding procedure.
