11 - 10 EXHAUST SYSTEM
EXHAUST PIPE - 4.7L (Continued)
INSPECTION
Discard rusted clamps, broken or worn supports
and attaching parts. Replace a component with orig-
inal equipment parts, or equivalent. This will assure
proper alignment with other parts in the system and
provide acceptable exhaust noise levels.
INSTALLATION
(1) Connect the exhaust pipe(s) to the exhaust
manifold. Tighten the nuts to 26 N·m (19 ft. lbs.)
torque.
(2) Align and connect the exhaust pipe to the cat-
alytic converter flange (Fig. 13). Install exhaust
clamp and tighten clamp nuts to 41 N·m (33 ft. lbs.)
torque.
(3) Connect oxygen sensor connector(s).
(4) Lower the vehicle.
(5) Start the engine and inspect for exhaust leaks
and exhaust system contact with the body panels.
Adjust the alignment, if needed.

HEAT SHIELDS
DESCRIPTION
There are two types of heat shields used. One is
stamped steel the other is molded foil sheets. The
shields attach to the vehicle around the exhaust sys-
tem to prevent heat from the exhaust system from
entering the passenger area and other areas where
the heat can cause damage to other components (Fig.
14, 15, 16, 17, 18, 19, 20, 21, 22).
REMOVAL
(1) Raise and support the vehicle.
(2) Remove the screws and/or nuts holding the
heat shields to the frame and/or floor pan.
(3) When removing muffler heat shield, the muf-
fler front support bracket must be removed first.
(4) Slide the shields out around the exhaust sys-
tem.
