OE 032121065D — Coolant Flange for Audi

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

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.

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.

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.

Wholesale pricing for 032121065D 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.

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.
