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 operation time.
Avoid application of rust prevention compounds or undercoating materials to exhaust system floor pan heat shields. Light overspray near the edges is permitted. Application of coating will result in excessive floor pan temperatures and objectionable fumes.
The exhaust system consists of a catalytic converter, exhaust pipe, muffler, exhaust isolators, clamps, and heat shield. The system is separated into sections for service, the catalytic converter, the exhaust pipe, and the muffler. There are upstream and downstream oxygen sensors located in the catalytic converter.
The catalytic converter is bolted to the turbo charger and supported by an transmission mounting bracket. The catalytic converter outlet tube is also supported by an isolator.
- The exhaust system must be properly aligned to prevent stress, leakage and body contact. If the system contacts any body panel, it may amplify objectionable noises originating from the engine or body.
- When inspecting an exhaust system, critically inspect for cracked or loose joints, stripped screw or bolt threads, corrosion damage and worn, cracked or broken hangers. Replace all components that are badly corroded or damaged. DO NOT attempt to repair.
- When replacement is required, use original equipment parts (or their equivalent). This will assure proper alignment and provide acceptable exhaust noise levels.
