URO 06C121111E Engine Coolant Thermostat Housing Assembly

The URO Parts 06C121111E is a complete engine coolant thermostat and water inlet assembly designed as a direct-fit replacement for Audi 3.0L V6 applications. This assembly regulates coolant flow through the engine based on temperature, keeping the engine at its optimal operating temperature for peak efficiency and longevity.

The thermostat remains closed on cold starts to accelerate warm-up, then opens once the engine reaches operating temperature to allow coolant to circulate. A failed thermostat — whether stuck open or stuck closed — can result in engine overheating, poor fuel economy, or failure to reach proper operating temperature.

Key Features:

• Manufactured to factory housing dimensions for a reliable, bolt-on installation
• High-quality alloy or composite material that is temperature-stable, resisting warping or cracking that can lead to coolant leaks
• Includes thermostat, housing, and sealing gasket — everything needed for a complete replacement
• High-flow OE-style design for optimal engine cooling performance
• Manufactured in ISO/IATF 16949 certified facilities to ensure consistent quality standards
