This is the BEMWQ Cooling Oil Cooler (Part Number: 2721880001 / A2721880001), a vital heat exchange component within the engine's lubrication and cooling system. It is designed for Mercedes-Benz vehicles equipped with the M272 engine (including W204, W211, X204, and W636 chassis), responsible for transferring excess heat away from the circulating engine oil to the coolant circuit. By maintaining the oil at an optimal operating temperature, it prevents viscosity breakdown, ensures consistent lubrication, and protects the engine under high-load or demanding driving conditions.

• Precision Fitment:​ Specifically engineered for Mercedes-Benz chassis models including C-Class (W204), E-Class (W211), GLK-Class (X204), and Citan (W636) with M272 engines, ensuring a direct OEM-standard fit without modification.

• High-Efficiency Thermal Design:​ Manufactured with high-quality, high-thermal-conductivity aluminum alloy and optimized internal flow channels to maximize heat dissipation efficiency and ensure rapid cooling of engine oil.

• OE Specifications & Durability:​ Built to match original equipment standards in terms of core dimensions, port threading, and sealing surfaces. It features corrosion-resistant materials and robust brazed construction to withstand high oil pressures and extreme engine bay temperatures without leaking.

• Protects Engine & Extends Longevity:​ Replacing a clogged, leaking, or inefficient oil cooler prevents engine oil from overheating and breaking down (losing viscosity), which is critical for preventing premature engine wear, sludge buildup, and costly internal engine damage.

• Maintains Optimal Performance:​ Ensures the engine oil stays within the ideal temperature range, allowing the lubrication system to function effectively. This helps maintain smooth engine operation, stable oil pressure, and overall engine efficiency.

• Secure & Direct Replacement:​ Matches the factory unit's exact mounting points and line connections, allowing for a straightforward, leak-free installation for both professional workshops and DIY enthusiasts performing cooling system maintenance.
