Parts for your 2017 Nissan Pulsar-Cluth slave cylinder

2017 Nissan Pulsar cluth-slave-cylinder: what it does and when to sort it

Across the 2017 Nissan Pulsar range, the presence of a cluth-slave-cylinder depends on the transmission. Technical sources including the Nissan Electronic Service Manual (ESM) for Pulsar/Sentra B17 (section CL – Clutch), the Pulsar C12 ESM (CL), and the Exedy Australia & NZ catalogue confirm that manual-transmission Pulsars use a concentric cluth-slave-cylinder (CSC) integrated with the release bearing inside the bellhousing. Xtronic CVT models don’t have a clutch at all, so a cluth-slave-cylinder isn’t fitted on those variants.

On manual models, the cluth-slave-cylinder converts pedal effort into smooth clutch release. The clutch master cylinder builds hydraulic pressure, the CSC then pushes directly on the pressure plate via the integrated release bearing. Being concentric and internal keeps pedal feel tidy and reduces linkage complexity, but it does mean gearbox removal is required to replace the unit.

• What drivers notice when a cluth-slave-cylinder is tired: spongy or low pedal, difficulty selecting gears (especially first/reverse), clutch drag at the lights, fluid loss or dampness at the bellhousing weep point, and occasional slip if the bearing binds.
• Fluid and bleeding: the Pulsar’s clutch shares the brake fluid reservoir on most trims. Use the Nissan-specified DOT 3 (or DOT 4 if permitted by the cap/manual) and keep the level between marks. Don’t let it run low during bleeding.

1. Servicing tip: check clutch fluid condition at every service. Dark or contaminated fluid? Flush it. A 24–36 month or 40,000–60,000 km interval suits Aussie and Kiwi conditions.
2. When replacing the clutch, it’s smart practice to renew the CSC at the same time—labour overlaps and a fresh unit helps avoid pulling the box again.
3. After any hydraulic work, bleed the system thoroughly. A pressure or vacuum bleed works well, finish with a pedal bleed to firm it up.
4. Use quality parts that match the VIN, Pulsar manual variants (B17 sedan and applicable C12 hatch/SSS) list a CSC in OEM and reputable aftermarket catalogues.

Because the CSC lives inside the transmission, replacement involves removing the gearbox, inspecting the clutch disc and pressure plate, checking the spigot/pilot area, and refilling/bleeding with correct fluid. A workshop following the Nissan ESM torque specs and procedures will keep the pedal feel consistent and gear changes crisp. For CVT Pulsars, none of this applies—there’s no cluth-slave-cylinder to service.

Popular questions about the 2017 Nissan Pulsar cluth-slave-cylinder

Does every 2017 Pulsar have a cluth-slave-cylinder?
No. Manual models do (it’s a concentric unit inside the bellhousing), but Xtronic CVT versions don’t use a clutch or cluth-slave-cylinder at all.

Should the cluth-slave-cylinder be replaced with the clutch?
Yes, that’s best practice. The CSC is internal, so the extra part cost is minor compared to the labour of removing the gearbox twice if it fails later.

What fluid is used and how often should it be changed?
Use Nissan-approved DOT 3 (or DOT 4 if specified). Check level every service and flush every 24–36 months or 40,000–60,000 km, especially in hot or hilly Aussie and Kiwi driving.
