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 (for example: 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.

• The flex joint in the front exhaust pipe must not be bent more than 10 degrees, otherwise it may be damaged.

• Replace gaskets and self locking nuts.

• After exhaust system repairs, make sure the exhaust system is not under stress and is far enough from the body. If necessary, loosen the clamp and align the muffler and exhaust pipe as such that there is adequate distance to the body and the weight is evenly distributed among the suspended mounts.

• Exhaust manifold and turbocharger are one component, removing and installing. Refer to => [ Turbocharger ] Turbocharger.
