(6) Start the engine and inspect for exhaust leaks
and exhaust system contact with the body panels.
Adjust the alignment, if needed.

RESONATOR

REMOVAL
(1) Disconnect the battery negative cables.
(2) Raise vehicle on hoist.
(3) Remove the exhaust clamps from the resonator
to extension pipes (Fig. 17).
(4) Separate the resonator from the front and rear
extension pipes (Fig. 17) and remove the resonator
from the vehicle.
INSTALLATION
(1) Assemble the resonator to the front and rear
extension pipes (Fig. 17).
(2) Install new exhaust clamps, align the exhaust
system, and tighten the exhaust clamps to 48 N·m
(35 ft. lbs.) torque.
(3) Lower the vehicle.
(4) Connect the battery negative cables.
(5) Start the engine and inspect for exhaust leaks.

TURBOCHARGER

DESCRIPTION
The turbocharger is an exhaust-driven super-
charger which increases the pressure and density of
the air entering the engine. With the increase of air
entering the engine, more fuel can be injected into
the cylinders, which creates more power during com-
bustion.
The turbocharger assembly consists of four (4)
major component systems (Fig. 18) (Fig. 19):
• Turbine section
• Compressor section
• Bearing housing
• Wastegate
OPERATION
Exhaust gas pressure and energy drive the tur-
bine, which in turn drives a centrifugal compressor
that compresses the inlet air, and forces the air into
the engine through the charge air cooler and plumb-
ing. Since heat is a by-product of this compression,
the air must pass through a charge air cooler to cool
the incoming air and maintain power and efficiency.
Increasing air flow to the engine provides:
• Improved engine performance
• Lower exhaust smoke density
• Improved operating economy
• Altitude compensation
• Noise reduction.
