The BEMWQ Cooling Thermostat (Part No.: 2722000415) is a high-quality aftermarket replacement component designed specifically for Mercedes-Benz vehicles equipped with the M272 V6 engine. It is fully compatible with popular chassis models including the W204 (C-Class), V212 (E-Class), W211 (E-Class), and X204 (GLK-Class). This thermostat is engineered to match the original equipment (OE) specifications, featuring a standard 100°C (212°F) opening temperature to precisely regulate engine coolant flow and maintain optimal operating temperatures.

• Exact OEM Specification:​ Manufactured to the OE standard 2722000415, ensuring the valve opens at exactly 100°C to guarantee factory-accurate engine warmth-up times and temperature stability.

• Complete Installation Kit:​ Typically supplied inclusive of a factory-spec gasket/seal ring, allowing for a direct, leak-free installation without the need for sourcing separate sealing hardware.

• Durable Construction:​ Built with robust materials designed to withstand constant thermal cycling, coolant corrosion, and high under-hood temperatures for extended service life.

• Precision Fitment:​ Engineered for a seamless drop-in fit on M272 engines, aligning perfectly with the thermostat housing ports and mounting points on W204, W211, V212, and X204 models.

• Prevention of Overheating & Engine Damage:​ Effectively eliminates the risk of the thermostat sticking closed, which is a common failure mode that can lead to catastrophic engine overheating, cylinder head warping, or blown head gaskets.

• Restored Fuel Efficiency & Cabin Heat:​ Fixes issues caused by a thermostat stuck in the open position—such as the engine never reaching operating temperature, poor fuel economy, a rich-running condition, and weak cabin heater performance.

• Reliable Operation & Diagnostics:​ Helps clear common thermostat-related fault codes (e.g., open circuit codes for MAP-controlled thermostats) and silences constantly running high-speed cooling fans, restoring normal ECU-controlled operation.

• Cost-Effective Maintenance Solution:​ Offers a dependable and economical alternative to dealer parts for routine cooling system maintenance (often recommended around 50,000-mile intervals), backed by the quality focus of the BEMWQ brand.
