Parts for your 2006 Toyota Hilux-Cluth slave cylinder

2006 Toyota Hilux clutch slave cylinder: what it does and when to service it

Technical sources confirm the 2006 Toyota Hilux (N70 series) with a manual gearbox uses a hydraulic clutch system with a clutch slave cylinder. Toyota’s Electronic Parts Catalogue lists the “Clutch Release Cylinder Sub-Assembly” (commonly called the slave cylinder) for 2005–2015 Hilux variants, including KUN and GGN models, with typical part numbers such as 31470-0K010/0K011. The Toyota Repair Manual for the N70 Hilux includes procedures for clutch hydraulic bleeding and slave cylinder removal/installation, further verifying fitment. Automatic-transmission Hilux models do not use a clutch slave cylinder.

On a manual 2006 Hilux, the clutch slave cylinder (cluth-slave-cylinder) converts hydraulic pressure from the clutch master into mechanical movement at the fork, disengaging the clutch so gears slip in smoothly. It’s bolted to the bellhousing, easy to spot from under the ute, and is a straightforward bit of kit that cops a lot of heat and road grime.

As part of routine servicing, it’s smart to check the clutch hydraulic fluid level and condition. The system typically uses DOT 3 or DOT 4 brake fluid—check the cap and handbook—and prefers fresh, clean fluid. Cloudy, dark or contaminated fluid is a sign it’s time for a flush and bleed. Most workshops in AU/NZ treat clutch fluid like brake fluid and refresh it about every 2 years or 40,000 km. A quick bleed can sharpen pedal feel and help the clutch release cleanly.

If the cluth-slave-cylinder starts weeping, you’ll often notice a soft or sinking pedal, difficulty selecting first or reverse, or fluid drips near the bellhousing. At that point, replacement is usually the go-to. The job is typically:

• Crack the line with a flare-nut spanner, unbolt the slave, swap in the new unit with the pushrod seated on the fork, reconnect the line.
• Bleed the system (gravity, pedal, or vacuum) until pedal feel is firm and free of air.
• Top the reservoir and check for dry joins. Always torque fasteners and line fittings to spec from the Toyota repair manual.

Given the age of a 2006 Hilux, many owners replace the master and slave as a pair for long-term reliability, especially if the clutch is being done. Using quality parts matching the Toyota EPC listing keeps the pedal light, the shifts tidy, and the ute working hard without complaints.

FAQs

Does a 2006 Toyota Hilux have a cluth-slave-cylinder?

Yes—if it’s a manual. The 2006 Hilux uses a hydraulic clutch with a slave cylinder mounted on the bellhousing to move the release fork. Automatic models don’t have one because they use a torque converter instead of a manual clutch.

What are the signs the clutch slave cylinder is failing on a 2006 Hilux?

Common giveaways include a spongy or sinking clutch pedal, trouble selecting gears (especially first and reverse), fluid loss from the reservoir, and dampness or drips around the bellhousing. If ignored, air enters the system and shifting gets progressively worse.

How often should the clutch hydraulic fluid be changed in a 2006 Hilux?

Most workshops in Australia and New Zealand recommend refreshing clutch fluid about every 2 years or 40,000 km, similar to brake fluid intervals. Harsh use—towing, off-road, or lots of stop-start—can justify more frequent checks and bleeding.
