M272 Engine Technical Data

The M272 engine is a V6 family of motors based on its predecessor the M112 V6 motor and consists of an aluminum engine block with a 90° V-angle including silicon aluminum lined cylinders, aluminum DOHC cylinder heads that have 4 valves per cylinder, forged steel connecting rods, one-piece cast crankshaft, iron-coated aluminum pistons and a magnesium intake manifold.

Direct injection is used in a limited fashion on the 3.5 L V6, whereas others use conventional port fuel injection. The M112 balance shaft is installed in the engine block between the cylinder banks to deal with vibrations in the 90 degree V6 design. A dual-length, variable Length intake manifold is fitted to optimize engine flexibility.

Continuous VVT (variable valve timing) was adopted for the first time, and is featured on both the intake and exhaust camshafts, each can be varied through a range of 40 degrees. Electronic coolant flow control has replaced the mechanical thermostat for improved engine warm-up and optimum control of engine temperature. The M272 was replace by its successor the M276.

Known M272 Engine Issues

M272 engines sold between 2004 and 2008 with engine serial numbers below 2729..30 468993 often show early wear of the balance shaft gears causing the check engine light to illuminate and the vehicle to misfire and/or stop working, requiring extensive repairs.

These engines also have a common issue with the plastic lever breaking that operates opening and closing of the variable length intake manifold, aftermarket replacement levers made of metal are available.
