642-090-13-86-80 | Genuine Garrett® Turbocharger GB2060 For Mercedes ML/GL/GLK/S350

More power: It forces extra air into the engine, allowing more fuel to be burned efficiently.

More torque: Very useful for trucks carrying heavy loads or climbing hills.

Better efficiency: A turbo uses energy from the engine's exhaust that would otherwise be wasted.

Smaller engine, similar power: A smaller turbocharged engine can produce power comparable to a larger naturally aspirated engine.

Better performance at altitude: It helps compensate for thinner air at higher elevations.

Loss of power — The truck feels weak, especially when accelerating or going uphill.

Slow acceleration — The engine doesn't build boost normally.

Black smoke — Too much fuel and not enough air can cause excessive black exhaust smoke.

Blue or gray smoke — Can indicate engine oil getting into the intake/exhaust through a damaged turbo.

Whining or siren-like noise — A loud high-pitched whine can indicate worn turbo bearings or a damaged compressor/turbine.

Oil consumption — The engine may start using more oil than normal.

Check-engine light — The engine computer may detect low or excessive boost.

Poor fuel economy — A turbo problem can affect how efficiently the engine burns fuel.

Boost pressure problems — A boost gauge may show lower-than-normal boost or unstable boost.

Oil around turbo piping — A small amount of oil mist can be normal on some systems, but significant oil accumulation can indicate a problem.
