Exhaust System: Description and Operation

Exhaust System

Special tools, testers and auxiliary items required

• Ring wrench for oxygen sensor (3337)

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. for fuel, hydraulic, additive, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.

• To prevent damages to the lines, make sure there is sufficient clearance to all moving or hot components.

• After exhaust system repairs, make sure exhaust system is not under stress and that it has sufficient clearance from the bodywork. If necessary, loosen double clamps and clamp and align exhaust pipe so that sufficient clearance is maintained to the bodywork and support rings carry uniform loads.

• Replace self locking nuts.

• Do not use sealants containing silicone. Particles of silicone drawn into the engine, will not be burnt in the engine and damage the oxygen sensor.
