Exhaust System: Description and Operation

General Repair Information

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route lines of all types (e.g. fuel, hydraulic, Evaporative Emission (EVAP) , coolant, refrigerant, brake or vacuum) and electrical wires so that the original path is followed.

• To prevent damage to the lines, make sure there is 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 support rings carry uniform loads.

• Gaskets and self locking nuts must be replaced.
