Fiat Clutch Slave Cylinder for Grand Siena Palio Siena– 512007010

 OE Cross Reference

Technical Reference

Notes

Three Models, One Clutch Slave Cylinder
The Grand Siena, Palio and Siena were all developed under the same Fiat platform program, built around parts commonality as a deliberate engineering requirement. The same clutch slave cylinder — OE 512007010 / 55226158 — runs across the 1.4 8V and 1.6 16V variants of all three models. For a distributor, that means one SKU covers three separate Fiat model names across multiple engine configurations, sold across Brazil, Argentina, South Africa, India and several other markets where this vehicle family was produced and sold.

Two OE Numbers, Same Part
The CS052 cross-references to both 512007010 and 55226158. The first is the primary Fiat OE number. The second, 55226158, appears in Magneti Marelli catalog systems, which Fiat used as a parallel parts numbering structure for components sourced through their supplier network. Both numbers describe the same specification. Distributors sourcing through local Fiat dealer catalogs may encounter either number depending on the market and catalog edition — both confirm this is the correct part.

Where Demand Comes From
The Palio family was designed for markets where independent workshops handle the majority of vehicle maintenance. Fiat's engineering brief explicitly required that parts be serviceable without specialist dealer equipment. That design decision matters for the aftermarket: these vehicles are maintained through local distributor channels, not dealer service networks, which means clutch hydraulic parts move through independent parts importers and regional wholesalers rather than OEM dealer supply chains.
The Grand Siena remained one of the most actively traded used cars in Brazil well after production ended — discontinued models drive aftermarket demand up, not down, as dealer OEM parts supply contracts while the vehicle population stays on the road. Distributors in Brazil, Argentina and sub-Saharan Africa who supply workshops servicing this vehicle family see consistent repeat orders for clutch hydraulic components precisely because these are high-mileage daily-use vehicles maintained on cost.

Supply Position
The CS052 sits in the same catalog section as clutch master cylinders and brake components for the same Fiat platform. Because the Palio/Siena/Grand Siena share hydraulic specifications across the range, a distributor covering this vehicle family can often cover multiple applications with a small number of SKUs. The CS052 is one of those core line items — high-frequency replacement, broad model coverage, two active OE references that appear across multiple catalog systems in its key markets.

Why This Part Appears in Brazilian, Argentine and South African Catalogs Simultaneously
Parts distributors sourcing for Fiat markets often notice that 512007010 appears in local Brazilian aftermarket catalogs, while 55226158 turns up in South African and Argentine distributor systems. This happens because Fiat's regional subsidiaries sometimes adopted different numbering conventions for the same component, particularly for parts sourced from suppliers like Magneti Marelli under dual OE reference agreements. The practical result is that a distributor in Johannesburg and one in São Paulo may be looking at different numbers for the same clutch slave cylinder. The CS052 consolidates both references into a single verified specification, confirmed against both OE numbers. For importers building a multi-market Fiat catalog, this cross-reference coverage reduces the risk of stocking duplicate SKUs or creating catalog gaps between regional number systems.

Q1: 512007010 and 55226158 are both listed — which one do I search in my local catalog?
Use whichever number your local Fiat or aftermarket catalog system shows. Both reference the same part. Brazilian aftermarket catalogs typically show 512007010; South African and Argentine systems more commonly list 55226158.

Q2: Does the 1.6 16V Siena use the same slave cylinder as the 1.4 8V models?
Yes — the CS052 covers both the 1.4 8V and 1.6 16V applications across the Siena, Palio and Grand Siena range. The clutch hydraulic specification was shared across these engine variants on the same platform.

Q3: Does this cover Brazilian flex-fuel versions?
The CS052 covers the 1.4 8V and 1.6 16V engine specifications. Brazilian flex-fuel versions of these engines use the same clutch hydraulic components — the fuel system is independent of the clutch system.

Q4: Grand Siena production has ended. Is supply for this part going to remain available?
Production ending increases aftermarket demand for replacement parts, since dealer OEM supply decreases while vehicles remain in service. As long as these vehicles are on the road — and they remain actively traded in used car markets across Brazil and other regions — demand for the CS052 continues.

Q5: Can this be supplied under private label packaging for our own brand?Yes. Custom packaging, label printing and logo branding are available for OEM/ODM bulk orders targeting any market.
