Exhaust System: Description and Operation
Exhaust System, Emission Controls
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
• Route all lines and wires in their original locations.
• Ensure sufficient clearance to all moving or hot components.
• After exhaust system repairs, make sure exhaust system is not under stress and is far enough from the body. If necessary, loosen the clamping sleeve and align the muffler and front exhaust pipe so that there is enough clearance all the way around. The suspended mounts must be loaded evenly.
• Gaskets and self-locking nuts must be replaced.
