Before checking the turbocharger,
make sure that the engine has cooled
down to normal temperature. Before
checking, make sure that the
compressor wheel is not rotating.
* Otherwise, you could get burned.
* If you are caught in a rotating compressor
wheel, you will suffer laceration.
Make sure that there is no intake air
leak in the piping to the compressor of
the turbocharger.
* If there is intake air leak, insufficient boost
pressure could occur, which could cause
deterioration in the exhaust gas properties.
Check that the compressor or turbine
of the turbocharger is not dirty.
* If the compressor or turbine of the turbocharger
is dirty, performance degradation of the
turbocharger may occur, which could cause
power reduction.
Do not touch the exhaust muffler
immediately after the engine is
stopped.
• Make sure that the engine is cooled down
to the normal temperature.
* Otherwise, you could get burned.
