Exhaust System
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
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 3-way catalytic converter rises to a high level after only a few minutes of engine operation. Failure to follow these instructions may result in personal injury.
CAUTION:
When repairing the exhaust system or removing exhaust components, disconnect all heated oxygen sensors (HO2S) at the wiring connectors to prevent damage to the HO2S and wiring harness. For additional information, refer to ELECTRONIC ENGINE CONTROLS
for the location of the HO2S.
The exhaust system:
- contains dual 3-way catalytic converters.
- has a crossover pipe downstream of the 3-way catalytic converters.
- has two upstream HO2S mounted before the 3-way catalytic converters.
- has a production muffler and tailpipe assembly which is a one-piece design.
