Exhaust System
WARNING:
The normal operating temperature of the exhaust system is very high. Never attempt to repair any part of the system until it has cooled. Be especially careful when working around the 3-way catalytic converter. The temperature of the catalytic converter rises to a high level after only a few minutes of engine operation.
CAUTION:
When repairing exhaust system or removing exhaust components, disconnect all heated oxygen sensors (HO2S) at the wiring connectors to prevent damage to the heated oxygen sensors and wiring harness. For additional information, refer to ELECTRONIC ENGINE CONTROLS
for location of the heated oxygen sensors.
CAUTION:
Do not use oil or grease-based lubricants on the isolators. They may case deterioration of the rubber.
CAUTION:
Oil or grease-based lubricants on the isolators may cause the exhaust hanger isolator to separate from the exhaust hanger bracket during vehicle operation.
NOTE:
Exhaust fasteners are of a torque prevailing design. Use only new fasteners with the same part number as the original. Torque values must be used as specified during reassembly to make sure of correct retention of exhaust components.
The exhaust system:
- contains a one-piece catalytic converter assembly, has one muffler assembly.
- has muffler brackets with isolators bolted to the body.
- has 2 heated oxygen sensors (HO2S) mounted to the one-piece catalytic converter assembly.
- has 2 catalyst monitor sensors mounted to the one-piece catalytic converter assembly.
- production muffler and tailpipe assembly is a one-piece design exhaust system.
