Mercedes Benz M272 Engine Parts Diagram Jun 2026

An electronically controlled unit that allows the engine to reach operating temperature faster.

A heavy-duty roller chain looping around the crankshaft gear, balance shaft gear, and the four camshaft adjusters.

Heavy-duty roller chain linking the crankshaft to the camshafts.

Small cylindrical components that sit between the camshaft lobes and the valves to automatically maintain zero valve clearance.

The foundation of the M272 is a cast-aluminum cylinder block with cast-iron cylinder liners. The parts diagram shows a , which is narrower than many V6s, allowing for a compact engine bay fit. Mercedes Benz M272 Engine Parts Diagram
