The Mercedes-Benz M272 engine family is a versatile and widely produced V6 powerplant. It found its way into almost every major Mercedes model from 2004 through 2013, including the C-Class, E-Class, ML-Class, and S-Class. Houses a dual overhead cam (DOHC) setup with
Understanding the layout of the Mercedes-Benz M272 V6 engine is crucial for both routine maintenance and addressing its well-known mechanical vulnerabilities. Introduced in 2004 as a successor to the M112, this engine featured advanced technologies like continuous variable valve timing (VVT) and a dual-stage intake manifold. 1. The Core Architecture: 90-Degree V6
While the M272 can reliably reach up to 300,000 kilometers with proper care, its diagram reveals several parts prone to premature wear: Desert Oasis European Auto Service & Repair Balance Shaft Gear:
When using an engine parts diagram to reassemble an M272 engine, keeping precise torque parameters is vital to avoid cracking the aluminum or magnesium parts. Thread Size Recommended Torque 130 Nm + 90° Turn Always use a new bolt (Stretch Bolt) Timing Chain Tensioner Replace the aluminum sealing ring Intake Manifold to Cylinder Head Tighten in a cross pattern from inside out Camshaft Position Sensor Bolt Do not overtighten the plastic housing Spark Plugs Do not use anti-seize compound 5. Summary Checklist for Parts Ordering A: Refer to your owner's manual or consult
The engine has an oil separator mounted to the cylinder block/valves that controls crankcase pressure and directs oil vapor back into the intake. Over time, the internal plastic diaphragms tear, leading to vacuum leaks, rough idling, high oil consumption, and unmetered air entering the engine. 3. Coolant Thermostat
These mechanisms advance or retard valve timing. They are a frequent point of inspection. Valves and Lifters: 24 hydraulic bucket lifters and valves.
