Coolant Hose Flange – 06A 121 132 (URO)

Description

Product Description

The 06A121132 Coolant Hose Flange  by URO Parts is an OE‑style replacement coolant outlet used on select Volkswagen and Audi 4‑cylinder engines (commonly associated with 1.8T applications, depending on engine code and model year). This multi‑port flange mounts to the engine and provides properly aligned connection points for coolant hoses, helping route coolant between the cylinder head, radiator circuit, and heater system to maintain stable operating temperature.

Plastic coolant flanges are a common leak point due to constant heat cycling and cooling system pressure. Over time, the housing can become brittle, warp, or crack—leading to coolant seepage, low coolant warnings, and overheating risk. Replacing the worn unit with this URO 06A121132 flange restores leak‑free sealing and dependable coolant circulation.
