Radiator Water Flange – 3C0 122 291 (Hudson)

Description

Product Description

The 3C0122291 Radiator Water Flange by Hudson is an OE‑style replacement used on various Volkswagen and Audi models. This flange provides a secure, sealed junction where radiator and/or heater hoses connect to the engine or cooling module, ensuring correct coolant routing between the engine, radiator, and heater circuit.

Over time, the original plastic flange is exposed to high temperatures, pressure, and vibration, which can cause it to become brittle, warp, or crack. Hose barbs may break and sealing surfaces can deform, leading to coolant leaks, gradual coolant loss, and potential overheating. Replacing the damaged unit with this Hudson 3C0122291 flange restores a tight, leak‑free connection and helps maintain stable engine temperature.

Applications

Service Notes

• Replace any associated O‑rings and hose clamps during installation to ensure a long‑lasting seal.
