2722000415 BEMWQ Auto Cooling Thermostat for Mercedes Benz W204 V212 W211 M272

This is the BEMWQ Auto Cooling Thermostat (Part Number: 2722000415 / A2722000415), a critical temperature-regulating component within the engine's cooling system. Designed for Mercedes-Benz vehicles equipped with the M272 engine, it controls the flow of coolant between the engine and the radiator. By opening and closing at a specified temperature (commonly 100°C / 212°F), it ensures the engine reaches and maintains its optimal operating temperature swiftly, preventing both overheating and over-cooling for efficient performance .

• Precision Fitment:​ Specifically engineered for Mercedes-Benz chassis models including C-Class (W204), E-Class (V212/W211), and other M272-equipped vehicles, ensuring a direct OEM-standard fit without modification .

• Integrated Housing Assembly:​ Typically supplied as a complete unit with the housing, sealing gasket/O-ring, and sometimes the coolant temperature sensor, made from durable, heat-resistant materials to withstand harsh engine bay conditions and prevent leaks .

• OE Specifications:​ Manufactured to match original equipment standards in terms of opening temperature, flow rate, electrical connectors (if applicable for map-controlled versions), and mounting points for seamless integration .

• Prevents Overheating & Engine Damage:​ Replacing a thermostat that is stuck closed avoids dangerous engine overheating, which can lead to warped cylinder heads, blown head gaskets, and extremely costly repairs .

• Restores Fuel Efficiency & Performance:​ Fixing a thermostat stuck open (which causes the engine to run too cold) helps restore proper fuel mixture, reduces unnecessary fuel consumption, prevents carbon buildup, and ensures optimal heater output .

• Complete & Direct Replacement:​ Often includes necessary seals and housings, allowing for a straightforward, hassle-free installation process for both professional mechanics and DIY enthusiasts, eliminating the need to source small gaskets separately .
