Typica l e xample
Hot engine components can cause injury from
burns. Before performing maintenance on the
engine, allow the engine and t he components to
cool.
The engine is equipped with a high-pressure
turbocharger (1) and a low-pressure turbocharger (4).
A regular visual inspection of both turbochargers is
recommended. If the turbocharger fails during engine
operation, damage to the turbocharger compressor
wheel and/or to the engine may occur. Damage to the
turbocharger compressor wheel can cause additional
damage to the pistons, the valves, and the cylinder
head.
