CATALYTIC CONVERTER

DESCRIPTION

The close coupled, three-way catalytic converter inlets
are connected to the exhaust manifolds by the use of
ball flange (1). The 2.7L and 3.5L RWD vehicles incor-
porate a flex joint downstream of the LH catalytic con-
verter to improve NVH. The 5.7L equipped RWD
vehicles incorprate a flex joint downstream of the LH
and RH catalytic converters. The 6.1L equipped RWD
vehicles do use a flex joint downstream of the LH and
RH catalytic converters.The left (4) and right (2) side
converter outlet pipe connects to the exhaust system.

REMOVAL

RIGHT HAND CATALYTIC CONVERTER

WARNING: The normal operating temperature of
the exhaust system is very high. therefore, never
work around or attempt to service any part of the
exhaust system until 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 of engine oper-
ation time.

1. Disconnect negative battery cable.

2. Raise vehicle on hoist.

3. Disconnect downstream oxygen sensor (2) connec-

tors.

4. Remove muffler and resonator (Refer to 11 -

EXHAUST SYSTEM/MUFFLER - REMOVAL).
