Parts for your 2007 Toyota Hilux-Cluth slave cylinder

2007 Toyota HiLux clutch slave cylinder (cluth-slave-cylinder): what it does and how to look after it

For the 2007 Toyota HiLux with a manual gearbox, a clutch slave cylinder is indeed fitted and relevant. Toyota refers to it as the “Clutch Release Cylinder”. Technical sources confirming this include: the Toyota Repair Manual for the 2005–2011 HiLux (AN10/AN20) which details the release cylinder and bleed procedure in the CL section, the Toyota Electronic Parts Catalogue listing “Cylinder Assy, Clutch Release” (commonly 31470-0K020 or 31470-0K030) for 2007 KUN/GGN models, and major clutch catalogues from Aisin and Exedy that supply an external slave cylinder for 2005–2015 HiLux models.

On a 2007 HiLux, the clutch slave cylinder’s job is pretty simple: convert pedal effort into hydraulic pressure so it can push the clutch fork and disengage the clutch. It’s mounted externally on the gearbox bellhousing, which makes checks and replacement a straightforward bit of spanner work compared with concentric (internal) units found on some other vehicles.

As part of regular servicing of a 2007-toyota-hilux cluth-slave-cylinder, it’s smart to:

• Check the shared brake/clutch fluid reservoir under the bonnet and keep it topped with fresh DOT 3 (or DOT 4) brake fluid.
• Inspect around the slave’s dust boot and line fittings for any dampness or weeping.
• Look for a spongy pedal, clutch drag when selecting gears, or fluid loss between services.
• Bleed the system if the pedal feels airy, using the bleed nipple on the slave. Keep the reservoir above MIN during bleeding.

Replacement is service-on-condition rather than at a fixed kilometre interval. If the boot is torn, the piston is corroded, or it’s leaking, replace the cylinder. Use quality parts (Toyota/Aisin/Exedy) and don’t forget to check the master cylinder and flexible hose at the same time—ageing hydraulics often fail in pairs. When fitting the new slave, avoid getting fluid on the clutch, snug the line fitting properly, tighten the two mounting bolts to the Toyota spec, then bleed until the pedal is firm and returns crisply. A short road test should confirm clean shifts and full disengagement. For best pedal feel and long life, refresh the clutch fluid every couple of years—cheap insurance on a hard‑working Aussie/Kiwi ute.

Where is the 2007 Toyota HiLux cluth-slave-cylinder located?

It’s bolted externally to the gearbox bellhousing, acting on the clutch fork via a short pushrod. Access is from underneath, a jack and stands make the job safer and easier.

What fluid should be used for the HiLux clutch hydraulics?

Use DOT 3 brake fluid (DOT 4 is acceptable). It shares the brake/clutch reservoir. Keep fluid off paintwork and always use a fresh, sealed bottle.

How do you bleed a 2007 HiLux cluth-slave-cylinder?

Top the reservoir, fit a clear hose to the slave’s bleed nipple, and have a helper pump and hold the pedal. Crack the nipple to release air/fluid, close it, and repeat until no bubbles appear. Keep the fluid level up throughout.
