Parts for your 2008 Honda Cr-v-Cluth slave cylinder

2008 Honda CR‑V clutch slave cylinder (cluth-slave-cylinder)

Honda’s own 2007–2011 CR‑V Service Manual and the Honda electronic parts catalogue confirm that 2008 CR‑V models equipped with a manual gearbox use a hydraulic clutch with a clutch slave cylinder, while automatic models don’t have one and therefore a cluth-slave-cylinder isn’t relevant to those vehicles. Haynes and Autodata coverage for the 3rd‑gen CR‑V back this up: manual variants use a master-and-slave hydraulic setup, automatics do not.

For owners of manual 2008 Honda CR‑Vs, the clutch slave cylinder is a small hydraulic actuator bolted to the transmission housing. When the clutch pedal is pressed, fluid pushed by the master cylinder travels down a line to the slave, which moves the release fork to disengage the clutch. It’s a simple, hard‑working bit that quietly makes every gear change smooth and predictable.

Because the system uses brake fluid, it benefits from the same kind of regular attention as the brakes. Honda schedules brake fluid replacement about every three years, doing the clutch circuit at the same time is smart maintenance. Use quality DOT 3 or DOT 4 fluid that meets Honda specs. Keeping the fluid clean helps prevent internal seal wear, corrosion, and spongy pedal feel.

• Common signs it’s on the way out:
  • Soft or sinking clutch pedal
  • Difficulty selecting gears, especially first and reverse
  • Visible fluid leaks or dampness around the slave cylinder boot or line fittings
  • Low fluid in the shared reservoir without obvious brake leaks

Inspection is straightforward: check for leaks under the bonnet at the reservoir and along the hydraulic line, then at the slave on the gearbox. Any fluid weep or torn dust boot warrants action. If the pedal feels airy, a bleed can restore firmness—attach a clear hose to the bleed nipple on the slave, maintain fluid level in the reservoir, and bleed until bubble‑free.

Replacement is a tidy driveway job for a competent home mechanic: safely raise the car, cap the line, unbolt the old unit, bench‑prime the new slave if possible, refit with new sealing washers where applicable, and torque fasteners to spec. Finish with a careful bleed and a quick road test. If the vehicle has high kilometres or the master shows similar age, replacing both at once can save a second round under the car. Opt for OEM or reputable aftermarket parts, and don’t mix old and new fluid. A good clutch feel makes daily driving around Aussie and Kiwi roads that much nicer.

• Does every 2008 Honda CR‑V have a clutch slave cylinder?
  No. Only manual‑transmission models use a clutch slave cylinder. Automatic CR‑Vs don’t have a clutch pedal or clutch hydraulics, so a cluth-slave-cylinder isn’t fitted or required.
• Where is the clutch slave cylinder on a 2008 CR‑V manual?
  It’s mounted on the outside of the transmission casing, with a hydraulic line running from the shared brake/clutch fluid reservoir. You’ll see a small actuator with a pushrod to the release fork and a bleed nipple for servicing.
• What fluid should be used and how often should it be changed?
  Use quality DOT 3 or DOT 4 brake fluid meeting Honda specifications. Aim to flush the clutch hydraulic circuit about every three years, or sooner if the fluid looks dark or you’ve had components replaced.
