Pump assembly
State whether the request is for the complete oil pump, an internal rotor set or a housing/timing-cover assembly.
Corolla lubrication system · B2B sourcing
Request Corolla engine oil pump assemblies, pump housings, pickup strainers and related drive components with engine-specific evidence.

Part and kit scope
Similar buyer terminology can describe different component counts or technical specifications. Use a line-by-line scope so quotations remain comparable.
State whether the request is for the complete oil pump, an internal rotor set or a housing/timing-cover assembly.
Confirm whether the pickup tube, screen, gasket and mounting hardware are separate or included lines.
List an oil-pump chain, sprocket, guide or tensioner only when the engine design and repair scope require them.
Relief-valve specification and housing passages must match the intended engine; visual similarity is insufficient.
Public identification evidence
Replacement oil pump
Melling manufacturer literature lists M538 for 2009–2017 Toyota Corolla 1.8L DOHC applications with 2ZR-FE.
M538 is a public aftermarket catalog reference, not a Toyota OE number or a universal 2ZR-family claim.
Toyota names and component references are used for identification. CorollaParts.com makes no Toyota authorization or genuine-parts supply claim.
Selection record
| Decision point | Buyer evidence | Risk controlled |
|---|---|---|
| Engine and revision | Complete engine code, production date and available OE/cross number | Separates pump revisions and timing-cover designs |
| Housing configuration | Front and rear photos, mounting face and passage layout | Controls bolt pattern, seal and oil-gallery alignment |
| Drive method | Crank-driven, chain-driven or engine-specific arrangement | Defines whether sprocket, chain or guide components apply |
| Pickup scope | Pickup tube/strainer shape and oil-pan configuration | Prevents an incompatible pickup or sump connection |
| Order basis | Complete pump, rotor kit, housing, strainer and quantity per line | Prevents unlike quotations from being compared as the same assembly |
Part-specific risk
On some engines the oil-pump housing and timing/front-cover design are closely related. Do not order from pump diameter or engine displacement alone. Confirm the full casting, mounting surface, oil passages, drive arrangement and whether the old housing is reusable.

Not necessarily. The pickup tube and screen may be separate. List them explicitly and provide photos of the sump-side arrangement.
No. The complete engine code, production point, housing and drive design are required. Displacement is only a broad starting point.
No. It is an aftermarket manufacturer catalog reference publicly associated with selected 2009–2017 Corolla 2ZR-FE applications.
