PART 8: MAINTENANCE AND SERVICE EXHAUST SYSTEM
(R05/10) Y53-6032 – 213 –
WARNING! If your vehicle becomes disabled,
the hot exhaust system could ignite dry
grass, brush, spilled fuel, or other material
that can cause fires which can lead to death,
personal injury and property damage. Do not
park or operate your vehicle in areas where
the hot exhaust system could cause a fire.
CAUTION: This truck is equipped with a diesel
particulate filter in order to meet both noise
and exhaust emissions requirements.
Removal or tampering with the unit will not
improve engine performance. Also tampering
is against the rules that are established by the
U.S. Code of Federal Regulations. The unit
may only be replaced with an approved part.
WARNING!
Do not operate engine with the tur-
bocharger intake piping disconnected. A suc-
tion 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 killed
or seriously injured. Always keep the intake pip-
ing connected when you will be running the
engine.
CAUTION: Operating the engine with the tur-
bocharger intake piping disconnected will
allow abrasive dust to enter the engine which
can cause equipment damage.
• 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.
