The hydraulic clutch system in your Acura RSX enables you to engage and disengage the clutch, which in turn allows you to drive the car. When your RSX clutch is giving you trouble, not disengaging all the way, or not shifting, you may need to bleed or change your RSX slave cylinder.
The slave cylinder in your Acura RSX is mounted to the transmission housing directly underneath your battery tray. Today I’ll be showing you how to change a Acura RSX slave cylinder to restore the hydraulic operation of your clutch system.

If you own a factory stereo in your Acura RSX, now’s a good time to find this code. Open your hood and you’ll begin with your battery.
Disconnect the negative terminal on your battery first and then remove. Then remove the positive terminal on the battery and begin removing the 12mm bolts that hold the battery tray to the front radiator support on your RSX.
Once you have your battery and battery tray removed from your engine bay, you can see your slave cylinder. Acura calls for you to remove the 10mm bolt above your shift linkage that holds the clutch line, but we’ll be skipping that part of our DIY Guide on how to change a Acura RSX slave cylinder.
Remove the two 12mm bolts that secure the slave cylinder to the outside of your transmission. Inspect the shift fork and fork grommet for damage and make sure the mechanism is free of any debris.
Depress the roll pins shown above, and pull on the clutch line to release it from the slave cylinder. Remove the rubber isolator (labeled E) and inspect for any tears or damage. Replace if needed.
Now that you have your slave cylinder removed, go ahead and assemble and install your new one by mounting the two 12mm bolts first. Tighten these 12mm bolts to 17 ft lbs of torque. Reconnect the clutch line but only if you are sure that the rubber isolator is in good shape, or you’ve replaced it.
Fill your RSX clutch master cylinder with DOT 3 fluid, and then reconnect the clutch line to your slave cylinder. Connect a hose to the bleeder screw of your Acura RSX clutch slave cylinder, and then submerge into a container filled with brake fluid. Open the bleed screw located on your RSX slave cylinder, and slowly depress your clutch pedal until no more bubbles come out from the bleeder.
Make sure to submerge the hose from the bleeder into a clear container, so you can see the bubbles and condition of the fluid escaping. Close or tighten the bleed fitting when your friend is holding down on the clutch pedal. Tighten the bleeder screw to 6 lb fts and do not exceed this torque, or you run the risk of ruining your brand new Acura RSX slave cylinder.
