A used OEM Audi Coolant Flange / Adapter, part number 06M121137AH, also replaces 06M121137AC and 06M121137M. This plastic manifold routes engine coolant through the block and to the heater core. A common failure on supercharged and turbocharged 3.0L V6 engines is a brittle plastic seam that cracks, causing a sudden coolant leak and potential overheating.
