The 1K0 122 291R coolant hose flange is a genuine-spec upper coolant hose coupling used on select Volkswagen applications equipped with the 2.5L engine. This dual-outlet connector serves as a sealed junction point in the engine cooling circuit, securing coolant hose connections and 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 can become brittle, warp at the sealing surface, or develop cracks at the hose connection points. This leads to coolant seepage, unexplained reservoir level drops, low-coolant warnings, and potential engine overheating. Replacing the worn unit with this OE-quality 1K0 122 291R restores a tight, dependable connection and reliable cooling system performance.
A failing coolant hose flange typically presents as visible coolant residue or active seepage at one of the hose connection points. The coolant reservoir may drop gradually without a clear external cause. Physical inspection often reveals surface cracking, brittleness, or deformation at the connector ports. Left unaddressed, a fully failed flange can result in rapid coolant loss and engine overheating. Proactive replacement avoids more costly repairs.

The 8W0 122 293A is a Genuine Audi OE upper coolant hose coupling for the Audi A4 (B9), A4 allroad, A5, and A5 Sportback equipped with the 2.0L 45 TFSI petrol engine (2017–2020). Positioned at the water pump housing, this flange connects the upper radiator coolant hose and includes a C-clip and seal in the box. Because this coupling is a single-use component, always install a new unit whenever the upper coolant hose is disturbed — no modifications required.
The 5N0 122 291C is an OE-style lower radiator coolant hose adapter by VIKA, engineered for the VW Tiguan Mk1 (5N-chassis) with the 2.0L four-cylinder engine. Positioned at the front lower radiator hose junction, this coupling piece connects the lower coolant hose to the radiator outlet port, completing the primary cooling circuit return path. It serves as a cost-effective alternative to the Genuine VW lower adapter. Always confirm fitment by VIN before ordering.
