Anti-lock Braking System (ABS)
PART 8: MAINTENANCE AND SERVICE
Service the air cleaner
fi
lter elements as speci
fi
ed in "PART
8: MAINTENANCE AND SERVICE". If your vehicle is
equipped with an optional air inlet restriction indicator, ser-
vice the
fi
lter elements when the air inlet restriction indicator
locks in the extreme Up position.
Paper elements require care and proper handling because
they are critical to engine service life.
Turbocharger
When servicing the air intake and exhaust systems on a
turbocharged engine, check the items that follow. If you
detect any de
fi
ciencies, take the vehicle to an authorized
dealer for servicing. Delay could lead to severe and ex-
pensive damage to your vehicle.
WARNING! Do not operate engine with tur-
bocharger intake piping disconnected. Work-
ing around a turbocharger with the intake
piping removed can be dangerous. 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 se-
riously injured. Always keep the intake piping
connected when you will be running the engine.
• 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
fl
ange gaskets.
• High Frequency Vibration: Vibration may indicate
turbo rotor imbalance. Have your dealer investigate
this immediately.
Exhaust System
Details of inspection and maintenance of your exhaust sys-
tem are covered under "Noise Control System".
