Product Description
Coolant Hose Flange 06H121132H for Audi A4 A5 A6 Q5 1.8T/2.0T — OEM Cooling System Connector
The Coolant Hose Flange with OEM reference number 06H121132H is a verified direct-fit replacement for a wide range of Audi and Volkswagen vehicles equipped with 1.8 TFSI and 2.0 TFSI/TSI engines from the EA888 Gen 2 engine family. This component, also known as an engine coolant outlet or inlet flange, is a critical part of the engine's cooling system, directing coolant flow between the engine and radiator.
The flange routes coolant to the thermostat housing, where the coolant temperature is assessed to ensure an efficient cooling process. These plastic components are subjected to high heat and pressure, leading to cracks and leaks over time. A failing flange can result in coolant leaks, loose connections, and engine overheating.
This OE-spec replacement flange is manufactured to precise OEM dimensions for easy bolt-on installation and reliable hose connections. It is constructed from high-quality materials (PA66 + GF30) and is heat- and corrosion-resistant, ensuring a tight seal and preventing dangerous coolant loss.

Installation & Maintenance Recommendations
⚠️ IMPORTANT: Coolant flange replacement requires mechanical competence and proper coolant handling. Professional installation recommended.
Installation Guidelines (Reference VW/Audi workshop manual for complete steps):
- Safety first — allow engine to cool completely before starting work
- Drain the cooling system — capture coolant for proper disposal
- Disconnect the coolant hoses from the old flange
- Disconnect the thermal switch electrical connector
- Remove the mounting bolts securing the flange
- Remove the old flange — note the position of the seal
- Clean the mounting surface thoroughly — remove all old sealant/gasket material
- Compare the new flange with the old unit — verify part number (06H121132H) matches
- Install the new seal (included with the flange)
- Install the new flange into position
- Torque mounting bolts to manufacturer specification
- Reconnect coolant hoses and thermal switch connector
- Refill cooling system with the correct VW/Audi-approved coolant
- Bleed the cooling system to remove air pockets
- Start engine, bring to operating temperature, and check for leaks
Maintenance Schedule:
- Inspect the coolant flange and hoses for leaks during every service
- Replace coolant every 5 years or 100,000 km (or per manufacturer recommendation)
- If the flange has failed, inspect the thermostat and cooling system for contamination
