URO Parts 1112000915 Engine Coolant Thermostat Assembly 87°C with Housing and Seal

The URO Parts 1112000915 is a complete engine coolant thermostat assembly designed as a direct OE-style replacement for Mercedes-Benz vehicles equipped with the M111 four-cylinder engine family. This assembly includes the thermostat element, housing, and sealing components, providing everything needed for a clean, complete cooling system repair.

The thermostat is calibrated to open at 87°C (189°F), which is the factory specification for these engines. It functions by remaining closed during warm-up to help the engine reach operating temperature quickly, then opening to route coolant through the radiator once the optimal threshold is reached — protecting the engine from both overheating and running too cold.

Key Features:

• Factory-spec 87°C opening temperature for precise engine temperature regulation
• Complete assembly includes thermostat, housing, and seal for a straightforward replacement
• High-flow OE-style design for optimal engine cooling performance
• Manufactured to factory housing dimensions for easy bolt-on installation
• High-quality, temperature-stable materials to resist warping or cracking
• Meets or exceeds OEM specifications
