Exhaust System: Description and Operation
Exhaust System Components
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
• Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.
• Ensure sufficient clearance to all moving or hot components.
• After exhaust system repairs, make sure the exhaust system is not under stress and that it has sufficient clearance from the bodywork. If necessary, loosen the clamp(s) and align the exhaust pipe so that sufficient clearance is maintained to the bodywork and the support rings carry uniform loads.
• Gaskets and self-locking nuts must be replaced.
