The 06H121132H Aluminum Coolant Flange is an , OE‑style replacement for select Volkswagen and Audi applications. This coolant outlet mounts to the engine and provides a secure connection point for the main coolant hose along with an auxiliary hose/bleeder port (application‑dependent), helping maintain proper coolant routing, system pressure, and stable operating temperature.
Factory plastic coolant flanges are a common failure point due to constant heat cycling and cooling system pressure. Over time they can warp, crack, or leak at the sealing surface—causing coolant loss, low‑coolant warnings, and overheating risk. Upgrading to this aluminum 06H121132H flange improves durability and helps reduce repeat leaks compared to plastic housings.
Used on select VW/Audi models that specify coolant flange/water outlet part number 06H121132H.
(Fitment varies by engine code and model year—confirm by VIN/parts catalog and match the hose/port layout.)
