OE 21355-3C510 — Gasket Water Pump LH for Hyundai

Match three things: the code on the part you are removing, the build-year range in the Applications table, and the mounting points visible in the reference photo. If all three line up, 21355-3C510 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

Aftermarket gasket water pump lh comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Incoming batches pass a dimensional check, a material look-up against the cooling system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the cooling system family — always confirm dimensions and connector layout before you swap.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Bulk pricing is tiered: 10 pieces, 50 pieces and full-carton quantities each carry a different unit rate. Piece price also moves with packing format and whether your own brand is printed on the carton, so tell us the landed quantity you are planning.
