Exhaust System
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. 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 service any part of the system until it has cooled. Be especially careful when working around the three way catalytic converter. The temperature of the three way catalytic 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 (HO2S) (9F472) at the wiring connectors to prevent damage to the heated oxygen sensors and wiring harness. Refer to REMOVAL & INSTALLATION
for location of the heated oxygen sensors.
The exhaust system is comprised of the components shown in the following illustrations.
