2741880101 BEMWQ Oil Cooler for Mercedes Benz W205 V212 V213 X253 X204 M274

The BEMWQ Oil Cooler (Part No.: 2741880101) is a high-efficiency thermal management component designed for Mercedes-Benz vehicles equipped with the M274 2.0L turbocharged inline-4 engine. It is fully compatible with chassis models including the W205 (C-Class), V212 (E-Class), V213 (E-Class), X253 (GLC-Class), and X204 (GLK-Class). This unit functions as a liquid-to-liquid heat exchanger, typically mounted at the engine block or filter housing, where it transfers excess heat from the circulating engine oil to the coolant, ensuring the lubricant stays within the optimal temperature range for consistent performance .

• Precision OEM Fitment:​ Manufactured to match the original equipment specification 2741880101, ensuring exact port alignment, thread engagement, and seamless integration with the M274 engine’s oil and coolant circuits without modification .

• High-Efficiency Heat Exchange:​ Constructed with a high-density aluminum core and precision-engineered internal turbulators or plates to maximize the surface area for heat transfer, effectively dissipating high thermal loads generated by the turbocharged M274 engine .

• Durable & Leak-Resistant Build:​ Built using robust materials and equipped with high-quality nitrile or Viton O-rings/seals that resist degradation from prolonged exposure to hot oil, coolant, and thermal cycling, preventing internal cross-leaks .

• Direct Bolt-On Design:​ Engineered as a complete assembly with integrated oil and coolant channels, allowing for a straightforward removal and replacement process using standard tools and existing mounting points .

• Preservation of Oil Quality & Viscosity:​ Prevents engine oil from overheating (which causes thinning, oxidation, and additive breakdown), ensuring the lubricant maintains its optimal viscosity to protect critical engine components like turbocharger bearings and camshafts .

• Reduction of Engine Wear & Overheating Risk:​ Maintains stable oil temperatures even under severe driving conditions (e.g., stop-and-go traffic, high-speed cruising, or towing), reducing friction-related wear and preventing heat-induced engine shutdowns or damage .

• Prevention of Fluid Contamination:​ Eliminates the common failure mode of internal seal rupture, which can lead to coolant mixing into the oil (causing a milky "mayonnaise" sludge) or oil leaking into the coolant, both of which are highly detrimental to the engine and cooling system .

• Cost-Effective Thermal Protection:​ Provides a dependable and economical alternative to dealership original parts for both corrective repairs (when dealing with leaks or clogs) and preventative maintenance, securing the long-term reliability and performance of the M274 engine .
