OE 021121050C — Coolant Flange for Volkswagen

Aftermarket coolant flange 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.

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.

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.

OE 021121050C is the factory reference for this coolant flange on selected Volkswagen models. The Applications table on this page lists the confirmed rows — check trim level and build year against your own fleet before ordering, because one reference can cover several body variants.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a coolant flange the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Wholesale pricing for 021121050C depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.
