Mercedes Benz M272 Engine Parts Diagram Access

The M272 engine assembly consists of several distinct mechanical systems: Motor Mechanicals

: A prominent feature is the Magnesium Intake Manifold , which includes variable-length intake runners and integrated swirl/tumble flaps to optimize air mixture at different RPMs. The Throttle Valve Actuator and Mass Air Flow (MAF) Sensor are typically shown positioned behind this assembly.

The M272 engine is a 3.5-liter V6 engine with a 90-degree V configuration. It features a single overhead camshaft (SOHC) design with two valves per cylinder. The engine produces 268 horsepower and 258 lb-ft of torque, making it suitable for a wide range of Mercedes-Benz models. The M272 engine is also equipped with a number of advanced technologies, including a variable intake manifold and a exhaust gas recirculation (EGR) system. The M272 engine is a 3

: One of its most distinctive features is the Magnesium Variable Intake Manifold . It uses internal "swirl flaps" to improve air-fuel mixing at low RPMs and switches to shorter runners for high-RPM power.

Before buying any parts for an M272, cross-reference the diagram with your engine serial number (stamped on the block near the starter). The difference between a pre-revision and post-revision balance shaft can mean the difference between a running engine and a pile of scrap metal.

Before diving into the nuts and bolts, it is critical to understand that the M272 exists in two distinct displacements: 2.5L (M272E25) and 3.5L (M272E35). While the block architecture is identical, internal components like the crankshaft, pistons, and connecting rods differ. Additionally, the M272 underwent a significant revision in 2007 (often called the "Facelift" version) to fix the infamous balance shaft sprocket issue.
