Parts for your 2007 Holden Captiva 5-Cluth slave cylinder

2007 Holden Captiva 5 clutch slave cylinder

Based on factory documentation for the Holden Captiva (CG Series, 2006–2008), the Opel Antara/GM Global workshop manual for the same platform, and GM/ACDelco parts cataloguing, the 2007 Holden Captiva 5 fitted with a manual transmission uses a hydraulic clutch with a concentric slave cylinder (CSC) integrated with the release bearing inside the bellhousing. Automatic variants don’t have a clutch hydraulic system at all, so there’s no slave cylinder on those models.

On manual Captiva 5s, the clutch slave cylinder’s job is simple but vital: it converts pedal effort, via hydraulic pressure from the clutch master cylinder, into movement of the release bearing so the clutch can disengage cleanly. Being a concentric unit, it sits around the gearbox input shaft, which keeps the layout compact and pedal feel consistent—handy for everyday Aussie and Kiwi driving where stop–start traffic is common.

There’s no routine internal servicing for the CSC itself because it’s sealed, but the clutch circuit shares brake fluid with the reservoir, so regular checks matter. Keeping the fluid fresh (use the grade specified by Holden—commonly DOT 4) helps protect seals and maintains a firm pedal. If the pedal goes spongy, gears get hard to select, or fluid level drops without obvious brake leaks, it’s time to inspect the clutch hydraulics.

• Typical symptoms of a failing slave cylinder: low or contaminated fluid, a soft or sinking pedal, difficulty engaging reverse/first when stationary, and fluid weeping from the bellhousing.
• Bleeding: pressure or vacuum bleeding via the bleed point is preferred to clear air, avoid pumping the pedal rapidly, which can aerate the fluid.

Replacement is more involved because the CSC lives inside the bellhousing. The gearbox has to come out, so most technicians will recommend fitting a complete clutch kit (friction disc and pressure plate) at the same time, along with the CSC, to avoid paying for repeat labour down the track. While it’s apart, it’s smart to inspect the rear main seal, flywheel surface, and the clutch line for any damage. After refit, the system should be bled thoroughly, fluid renewed, and pedal operation checked for consistent engagement height and smooth release.

Look after the fluid, keep an eye out for early signs of leakage, and when it’s time to replace, do the lot in one hit—your Captiva 5 will reward you with a lighter pedal and cleaner shifts for many more kilometres.

FAQs

Does a 2007 Holden Captiva 5 have a clutch slave cylinder?
Yes—if it’s a manual. It uses a concentric slave cylinder integrated with the release bearing inside the bellhousing. Automatic models don’t use a clutch or slave cylinder.

What are the signs the clutch slave cylinder is failing?
A soft or sinking pedal, difficulty selecting gears (especially first and reverse), a steadily dropping fluid level, and signs of fluid around the bellhousing are common. Contaminated or dark clutch fluid can also point to internal seal wear.

Can the clutch slave cylinder be replaced without removing the gearbox?
No. On the Captiva 5 manual, the slave is internal, so the transmission has to come out. That’s why most workshops recommend replacing the slave, clutch disc, and pressure plate together to save on labour and keep the system reliable.
