The hydraulic clutch on a Jeep Wrangler must be bled any time any part of the system has been removed or adjusted or when the fluid level has fallen low enough for air to have been drawn into the master cylinder. Bleeding the hydraulic clutch removes all air from the system to enable safe and proper clutch operation.
Fill the master cylinder with new brake fluid. Fill a small, clear plastic container with about two inches of brake fluid and place aside.
Raise the front of the Jeep on jack stands high enough to access the bleeder screw. The screw is located on the passenger side of the vehicle's transmission housing on four-cylinder Jeep Wrangler models. The screw is located on the left side of the transmission housing, immediately above the fitting for the clutch hydraulic line on six-cylinder Jeep Wrangler models.
Remove the dust cap covering the bleeder screw by unscrewing with a wrench. Place a section of plastic hosing over the screw. Place the other end into the container with brake fluid so that the hose is fully submerged in the fluid at the bottom.
Have a helper press down and hold the clutch pedal. Open the bleeder screw on the transmission and allow the fluid to flow through the hose.
Once the flow of bubbles and old master cylinder fluid has stopped, close the bleeder screw. Once the screw is closed, have the assistant release the clutch pedal.
Repeat steps 4 and 5 until all air is bled from the system as indicated by a solid stream of fluid from the bleeder screw and no air bubbles in the hose or container. Lower the vehicle and top off the fluid level.
