Catalytic Converter: Service and Repair

WARNING: The normal operating temperature of the exhaust system is very high. Never attempt to service any part of the system until it has cooled. Be especially careful when working around the catalytic converter. The temperature of the converter rises to a high level after only a few minutes of engine operation.

CAUTION: When servicing exhaust system or removing exhaust components, disconnect all heated oxygen sensors at the wiring connectors to prevent damage to the heated oxygen sensors and wiring harness.
