WARNING
DO NOT operate engine with turbo-
charger intake piping disconnected. A
suction is created when the engine is
running. This suction could draw your
hand or anything else near it into the
impeller fan. You could be injured. Al-
ways keep the intake piping connected
when you will be running the engine.
When servicing the air intake and exhaust
systems on a turbocharged engine, check
the items listed below:
Lubricating System
Check the oil lines, housing, and
connections. Look for leaks, damage, or
deterioration. Leaks could mean you have
damaged oil lines or oil seals.
Manifold
With the engine operating, check for
leaking manifold or flange gaskets.
High Frequency Vibration
Vibration may indicate turbo rotor
imbalance. Have your dealer investigate
this immediately. If you detect any
deficiencies, take the vehicle to an
authorized dealer for servicing. Delay could
lead to severe and expensive damage to
your vehicle.
Exhaust System
The exhaust system is part of the noise
and emission control system. Periodically
check the exhaust system for wear,
exhaust leaks, and loose or missing parts.
For details on how to maintain the
emissions components in the exhaust
system, see "Noise and Emission Control"
in your vehicle operator's manual. Please
refer to the engine operator's manual for
more details on how to maintain the
emissions components in the exhaust
system.
