Product Overview

The engine oil cooler, OEM number A2721880001, is fitted across a wide range of Mercedes-Benz models sharing the M272 V6 and M273 V8 engine family, including the C230, C280, C300, C350, E300, E350, S300, S320, S400, GLK280, GLK350, ML350, R350, and SLK280/350, covering the 2005-2013 production run. Since this oil cooler spans nearly every core Mercedes-Benz model line from this era, it's a high-turnover part number worth stocking in significant volume for distributors serving Mercedes-Benz cooling system parts demand.

A worn or leaking oil cooler typically shows up as visible oil leaks, low engine oil level, or engine overheating and reduced lubrication protection. GSK Auto manufactures this oil cooler to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is an Engine Oil Cooler?

Function: The engine oil cooler dissipates heat from engine oil as it circulates through the lubrication system, helping maintain a safe oil operating temperature.

Working Principle: Hot engine oil flows through the cooler, where heat is transferred away, typically using coolant from the engine's cooling system as the medium, before the cooled oil returns to circulate through the engine.

Importance: On a V6/V8-powered platform, a properly functioning oil cooler is essential for maintaining oil viscosity and preventing overheating, which can accelerate engine wear.

Common Failures & Signs: Visible oil leaks near the cooler housing. Low engine oil level from a slow leak. Engine overheating, especially under sustained load. Oil and coolant mixing internally if the cooler's seal fails.
