there is a write up here about replacing the clutch/removing the transmission and they wrote about bleeding the ACD. if i remember correctly you place your foot on the gas pedal and turn it ket to the "on" position the ACD pump will turn on and you will be able to bleed it. it might be beneficial to have a second person there to open the valve to release the fluid. i have done this in the past and it seemed to work but next time i think i will open it up and let gravity do its thing and it drain slowly.

gravity does not "bleed" the ACD system it actually lets air in the system. The proper way to do it is to fill the reservoir, turn the key to the on position but don't start the car, have some one climb under the car and pull the dirt cap off the bleeder port, put your 10mm brake line wrench on the fitting, with someone else pressing the gas pedal all the way to the floor crack the bleeder port open until the fluid flows without bubbles or interruption or "spurting" tighten the bleeder port before the person lifts there foot off the floor or the reservior runs out of fluid. Replace the dust cap, refill the reservior, install cap and enjoy!
Edit: I have actually done it by myself by attaching a string or bungee cord to hold the throttle wide open. Not recommended but it can be done by yourself.

Tools:
10mm wrench or socket
vacum hose
ACD fluid
how to:
this is a 2 man job, someone to turn the key to the on position and step on the gas pedal until the pump comes on and anther to loosen the 10mm bleed bolt on the TCase(bottom).
1. have a guy under the car ready on the bleed bolt with vacum hose on it diverting to a cup or bottle for excess acd fluid.
2. turn the key to on position, without starting, as soon as you turn the key, press on the gas peddle to the ground and notify your buddy under the car that its on.
3. the acd pump will come on and open the bleeder right away to let out air or fluid. Close bleeder when pump stops pumping usually after 3-5 seconds.
4. repeat 5-6 times.
good luck

thanks for the back up Josh. i wouldnt have thought about the gravity letting air in. now i know not to do it. i have in the past put a 20lb dumbell on the gas pedal as i was underneath the car opening the valve lol. sometimes you have to do what you have to do to get it done lol

can i use a vacuum brake bleeder tool to bleed the ACD, i have one that's hocked up to the air compressor.
