CONVERTER-CATALYTIC
DESCRIPTION
WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY HIGH. THERE-
FORE, NEVER WORK AROUND OR ATTEMPT TO SERVICE ANY PART OF THE EXHAUST SYSTEMUNTIL IT
IS COOLED. SPECIAL CARE SHOULD BE TAKEN WHEN WORKING NEAR THE CATALYTIC CONVERTER.
THE TEMPERATURE OF THE CONVERTER RISES TO A HIGH LEVEL AFTER A SHORT PERIOD OFENGINE
OPERATION TIME.
CAUTION: DO NOT remove spark plug wires from plugs or by any other means short out cylinders. Failure
of the catalytic converter can occur due to a temperature increase caused by unburned fuel passing
through the converter.
The stainless steel catalytic converter body is designed to last the life of the vehicle. Excessive heat can result in
bulging or other distortion, but excessive heat will not be the fault of theconverter. If unburned fuel enters the con-
verter, overheating may occur. If a converter is heat-damaged, correct the cause of the damage at the same time
the converter is replaced. Also, inspect all other components of the exhaust system for heat damage.
Unleaded gasoline must be used to avoid contaminating the catalyst core.
50 State emission vehicles incorporate two mini catalytic converters located after the exhaust manifolds and before
the inline catalytic converter.
OPERATION
The catalytic converter captures and burns any unburned fuel mixture exiting the combustion chambers during the
exhaust stroke of the engine. This process aids in reducing emissions output.
REMOVAL
3.7L/4.7L ENGINE
1. Raise and support vehicle.
2. Saturate the bolts and nuts with heat valve lubri-
cant. Allow 5 minutes for penetration.
3. Disconnect oxygen sensor electrical connectors.
4. Remove clamp (4).
5. Remove bolts exhaust to manifold (2).
6. Remove catalytic converter (3).

8.3L ENGINE
1. Raise and support vehicle.
2. Saturate the bolts and nuts with heat valve lubri-
cant. Allow 5 minutes for penetration.
3. Disconnect oxygen sensor electrical connectors.
4. Remove LH exhaust pipe to manifold bolts (2),
retainers and nuts (1).
5. Remove LH catalytic converter to muffler clamp
nuts (4).
6. Rotate LH catalytic converters (6) from the muffler
(5).
7. Remove RH exhaust pipe to manifold bolts (2),
retainers and nuts (1).
8. Remove RH catalytic converter to muffler clamp
nuts (4).
9. Rotate RH catalytic converter (3) from the muffler
(5).
10. Remove clamps and nuts (4).
INSPECTION
Look at the stainless steel body of the converter, inspect for bulging or other distortion that could be a result of
overheating. If the converter has a heat shield attached make sure it is notbent or loose.
If you suspect internal damage to the catalyst, tapping the bottom of the catalyst with a rubber mallet may indicate
a damaged core.
INSTALLATION
3.7L/4.7L ENGINE
1. Install RH catalytic converter to exhaust clamp (4)
on RH catalytic converter (3) and position into
exhaust pipe (5).
2. Install and hand tighten RH catalytic converter to
exhaust manifold bolts (2).

5. Tighten all clamp nuts (4) to 52.2 Nꞏm (40 ft. lbs.)
torque.
6. Check the exhaust system for contact with the
body panels. A minimum of 25 mm (1.0 in.) is
required between the exhaust system components
and body/frame parts. Make the necessary adjust-
ments, if needed.
7. Check to ensure you have at least 25 mm clear-
ance to oil pan.
8. Plug in O2 sensor wiring.
9. Lower the vehicle.
10. Start the engine and inspect for exhaust leaks. Repair exhaust leaks asnecessary.

DIAGNOSIS AND TESTING
CHARGE AIR COOLER SYSTEM - LEAKS
Low turbocharger boost pressure and low engine per-
formance can be caused by leaks in the charge air
cooler or plumbing. Fuel staining on the exhaust man-
ifold can also be an indication that there are leaks in
the air system. The followingprocedure outlines how
to check for leaks in the charge air cooler system.
This procedure can also be used to check for leaks in
the wastegate signal line or the wastegate canister.
1. Loosen clamp and remove air inlet hose from tur-
bocharger.
2. Insert Special Tool 9022 Adapter into the turbo-
charger inlet. Tighten tool clamp to 8 Nꞏm (72 in.
lbs.).
CAUTION: Do not apply more than 138 kPa (20
psi) air pressure to the charge air cooler system,
severe damage to the charge air cooler system
may occur.
3. Connect a regulated air supply to air fitting on Tool
9022 Adapter. Set air pressure to a Maximum of
138 kPa (20 psi).
4. Using soapy water check the rubber sleeves, charge air cooler and intakemanifold for leaks.
5. Using soapy water check for leaks at the wastegate signal line, wastegate canister and wastegate command
valve.

REAR FRAME H-SECTION REPLACEMENT
CAUTION: This procedure is designed to replace the H-section/spare tire support located at the rear of the
frame assembly. Prior to any cutting, the vehicle must be mounted on the appropriate frame repair equip-
ment (“frame rack”), checked with three dimensional measuring equipment, and the necessary pull correc-
tions made. If damage remains in the frame beyond the area covered by this service part after the pull, the
frame must be replaced in its entirety.
1. Before proceeding with this repair procedure review the required service warnings and precautions. (Refer to 13
- FRAME & BUMPERS/FRAME - WARNING)

HEATER - INTAKE AIR
DESCRIPTION
The intake manifold air heater element assembly is located in the top of theintake manifold.
OPERATION
The air heater element is used to heat incoming air to the intake manifold. This is done to help engine starting and
improve driveability with cool or cold outside temperatures.
Electrical supply for the air heater element is controlled by the Engine Control Module (ECM) through the air heater
relay. Refer to Intake Manifold Air Heater Relay for more information.
One heavy-duty cable connects the air heater element to the air heater relay. This cable will supply 12 volts to an
individual heating element within the heater block assembly.
CAUTION: The heater elements are no longer grounded using an external ground strap. Grounding is now
accomplished using two electrically conductive gaskets. Failure to use these gaskets will result in faulty
heater element operation.
Refer to the Powertrain Diagnostic Procedures manual for electrical operation and complete description of the intake
heaters, including pre-heat and post-heat cycles.
REMOVAL
If servicing the heater element, the entire block/ele-
ment assembly must be replaced.
1. Disconnect both negative battery cables at both
batteries. Cover and isolate ends of both cables.
2. Remove both the intake manifold air intake tube
(above injection pump), and its rubber connector
hose (2).
