where is the DIY for the clutch fluid bleeding?

do i need 2 tighten valve after pressing clutch down or after bringing it back up?:mchase:

You pretty much need 2 people, Or go buy a speedbleeder, I bled my own clutch line after I installed my AP SS Clutch line...

here's one easy procedure:

Put the wrench on the end of the bleeder valve, put a hose over the nipple, put the other end of the hose in a cup of brake fluid, open the valve, press and release the pedal 20 times or so. Close the valve, get back in press and release the pedal...it will get stiff.

open the valve, press and release the pedal 20 times or so....

Releasing the pedal before closing the bleed screw will introduce air into the line.
Do not do this...

This only works when you have a speed bleeder....

This is of course the benefit of speedbleeders which have integral one-way check valves (therefore being able to bleed solo).

As cited, best to have two people when bleeding with the stock nipples.

Releasing the pedal before closing the bleed screw will introduce air into the line.
Do not do this...

just gravity bleed. takes more time, but you can do it by yourself with no headaches about getting air in the system.

Follow these steps, you'll be successful in doing so :

1.
Step 1

Open your hood and locate the clutch slave cylinder. It is usually toward the front of the car, near the bumper.
2.
Step 2

Place a container underneath the slave cylinder.
3.
Step 3

Open the bleeder valve by unscrewing it slightly. The bleeder valve should be under the slave cylinder and distinguishable because of the rubber cap on its end. You will have to remove this cap when opening the valve.
4.
Step 4

Let the fluid drip out until it eventually pours out in a steady stream. Keep an eye on the clutch fluid level; do not let it dip below the minimum line. If it is gets low use new fluid to top it off.
5.
Step 5

Close the bleeder valve as soon as the fluid begins to pour out continuously and replace the rubber cap.
6.
Step 6

Slowly pump the clutch a few times. If after a few pumps the clutch feels normal, then you are finished. If the clutch still feels too soft, you will have to repeat the process.
7.
Step 7

Top off the clutch fluid in the reservoir.

Good Luck ;)

:icon_no2: Obviously... you've never done this...
This thread is full of too much misinformation.

The steps for bleeding the clutch is the same as the brakes.
1) Open the hood and locate the slave cylinder. Its in the back of the engine bay, basically behind the oil filter, on the transmission. Depending on your height you may need to lay on top of the engine instead of standing on the driver's side.
2) Have someone pump the clutch pedal a few times and have them hold the pedal down.
3) Insert a hose over the bleed screw and run the hose into a container
4) Open the bleed screw and allow the fluid to flow into the container.
5) The person in the car holding the pedal will notice the pedal dropping to the floor. Once the pedal hits the floor DO NOT lift up on the pedal until the bleed screw is closed.
6) The guy in the car should yell out once it hits the floor, you close the bleed screw, THEN he can lift up on the pedal.
7) Pump the clutch pedal a few more times and repeat until you no longer see air bubbles coming out of the line.
8) Watch the fluid level in the brake reservoir and fill when needed.

+1 on the gravity bleed

though I'd add a step before everything:
siphon out most of the fluid from the clutch reservoir. then fill with fresh fluid.
Use a different color fluid if you can so you can make sure you've bled the whole system.
ATE super blue/gold is a good choice.

This thread is full of too much misinformation.

I'll take your word for it. I don't remember what an rx8 engine bay looks like actually. I didn't even realize he said find the slave in the engine bay.

though I still think there's no need to pump the pedal. Gravity bleeding (especially for such short line) is fine for the clutch.

My procedure for gravity bleed:
1. open clutch reservoir, siphon out most of the fluid
2. fill with fresh fluid.
3. find bleeder on clutch slave and attach clear tubing that leads to a container to catch the liquid. (i usually just use whatever bottle is laying around with a hole drilled on top)
4. open bleeder. watch fluid drip out
5. keep an eye on the reservoir. Fill when it gets low
6. have a beer
7. when fluid changes to fresh, close valve.
8. remove tubing, top off reservoir.
Presto magic!

EDIT
k, after writing this, I think I remember the rx8 shares the clutch and brake reservoirs.
Same procedure should work though. Someone correct me if I'm wrong so I don't give wrong info out.
It's how I do it on my s2k though.

Gravity method will of course work (eventually), but again you're really better off with two people so you can be assured you achieve the proper pedal pressure (air removed)... or install a speedbleeder nipple.

going to go with two person method, thanks:rock:

You only need to bleed the clutch if you are having problems with it.

Even then it may not help.

The clutch and the brakes are in the same system so when you bleed the brakes you are also refreshing the hydraulic pressure on the clutch and the fluid.

If you get air in that clutch line you will regret it.
