Catalytic Converter
Description
The catalytic converter is attached to the exhaust manifold using fasteners and a gasket for sealing.
The catalytic converter plays a major role in the emission control system. The catalytic converter operates as a gas
reactor. Its catalytic function is to speed the heat-producing chemical reaction of components in the exhaust gases in
order to reduce air pollutants.
Operation
Catalyst operation is dependent on its ability to store and release the oxygen needed to complete the emissions-
reducing chemical reactions. As a catalyst deteriorates, its ability to store oxygen is reduced. Since the catalyst’s
ability to store oxygen is somewhat related to proper operation, oxygen storage can be used as an indicator of cat-
alyst performance.
CAUTION:
Unleaded gasoline must be used in order to avoid damaging the catalyst core.
Removal & Installation
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 has 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-
ating time.
1. Disconnect the negative battery cable.
2. Remove the heat shield retaining bolt (1).
3. Remove the exhaust manifold (See Exhaust Manifold Removal & Installation in Section 02 Engine).
