Product Description
Mount holes, gear modulus and oil passage sizes fully match original parts. No cutting or modification is required during installation, and the unit delivers oil pressure output consistent with factory specifications. This design reduces installation time and avoids adjustments to engine structure.
Precision controlled rotor clearance maintains steady oil pressure at idle and high speeds within the 0-7000 RPM range. The unit continuously lubricates crankshaft, camshaft and timing chain components, reducing risks of dry-scuff and cylinder scoring during operation.
The pump housing is made of high-pressure die-cast aluminum alloy, with a lightweight structure and thermal conductivity to dissipate oil heat. Each unit undergoes pressure and leakage testing after casting to address sand-hole related risks and prevent oil pressure drop or leakage.
The drive gear is made of 40Cr quenched alloy steel with high-frequency hardened surface. This material and treatment support long-term high-speed operation without tooth wear or gear jumping, reducing the risk of pump failure warnings.
The one-piece double-layer stainless steel mesh filter traps metal debris and sludge, preventing rotor jamming. This structure extends the service life of both the oil pump and internal engine components by reducing contaminant intake.
Heat-treated rotor clearance supports stable oil supply under varied hot and cold conditions. Under regular driving conditions with scheduled oil changes, the service life of the pump ranges 150,000-200,000 km. Replacing a worn original pump with this unit can resolve low oil pressure warnings, abnormal idle noise, power loss and excessive engine wear, avoiding costly engine overhaul.

Yes, the two part numbers are fully interchangeable. 21310-2G011 is the upgraded replacement version, with identical mounting dimensions and interfaces for direct bolt-on installation.
Yes. It is compatible with 2009–2013 Hyundai and Kia 2.0L / 2.4L MPI models, including the ix35 and Tucson.
Common signs include an illuminated oil pressure warning light (more noticeable at idle), abnormal engine noise from the timing chain or hydraulic lifters, reduced engine power, and increased fuel consumption. Severe cases may lead to cylinder scuffing or crankshaft seizure.
Yes. The oil pump is driven by the timing chain, so the timing cover and chain need to be disassembled during replacement.
Replace the timing chain and tensioner with new parts, and clean the oil pump strainer and oil galleries thoroughly. Fasten bolts per factory torque specifications: 8–10 N·m for pump body bolts, and 12–15 N·m for the sprocket bolt. After installation, refill with 5W-30 / 5W-40 full synthetic oil and verify oil pressure.
