The 1K0122291C Coolant Hose Flange by VAICO is an OE‑quality replacement designed for select Volkswagen and Audi applications. This connector is part of the engine cooling system and serves as a sealed junction point for coolant hoses, ensuring proper coolant routing between the engine, radiator, and heater circuit to maintain stable operating temperature and correct system pressure.
With age and repeated heat cycles, plastic coolant flanges/connectors can become brittle, warp at the sealing surface, or crack—often leading to coolant seepage, low‑coolant warnings, and potential overheating. Replacing the worn connector with VAICO 1K0122291C helps restore a tight, leak‑free connection and dependable cooling system performance.
Used on select VW/Audi models that specify coolant hose flange/connector part number 1K0122291C.
(Fitment varies by engine code and model year—confirm via VIN or parts catalog.)
