Exhaust system — general information (Opel Corsa B)

The exhaust system of all the models under consideration consists of three sections: intake, middle (intermediate) and rear. The main elements of the system are: the inlet pipe, the catalytic converter, the mufflers (intermediate and main), connecting tubular sections, mounting clamps, as well as support brackets and rubber loops by means of which the exhaust assembly is suspended from the underbody of the vehicle. The sections of the system are connected to each other by means of a single clamp connection (front section with intermediate) and one flange (intermediate section with rear). The joint of the middle and rear sections of the system is spring-loaded, which allows to compensate for the play that occurs during the movement of the car; in order to reduce the level of vibrations, a flexible insert is usually included in the receiving section of the system. Incorrect installation of the components and sections of the system leads to an increase in the level of noise and vibration transmitted to the car body.

Typical design of the exhaust system





Regularly inspect the entire system for signs of corrosion, deformation and mechanical damage. Check the reliability of fastener tightening. A breach of the tightness of components and their joints is fraught with the ingress of exhaust gases into the car interior. Defective components and sections are subject to replacement.

If the system is severely damaged by corrosion, a gas cutter may be required to separate its sections (alternatively, you can use a hacksaw or a pneumatic chisel - don't forget to wear safety glasses and gloves).

The system repair should be carried out in the following order:

• When removing components, move along the system path from the exhaust pipe to the engine;
• Lubricate the fasteners to be released with penetrating oil beforehand;
• Prepare the necessary replacement gaskets, hanging loops, clamps and fasteners in advance;
• Before installation, lubricate the threaded part of the fastener with anti-seize sealant;
• When installing components, ensure that there is sufficient clearance between the system sections and adjacent suspension/body components. Pay particular attention to the correct installation and secure fastening of the catalytic converter heat shield.
