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.
