Attention! Servicing of the exhaust system should be started only after its components have completely cooled down. Make sure that the car is securely fixed in the raised position.
The exhaust system of all models covered in this manual includes a flexible section that is extremely sensitive to severe kinks - exercise caution when servicing the system.
1. The exhaust system consists of exhaust manifolds, a downpipe, a catalytic converter, a muffler, an exhaust pipe, connecting pipe sections, mounting clamps, as well as support brackets and rubber loops by which the assembly is suspended from the bottom of the car. 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.
2. Regularly inspect the entire system for signs of corrosion, deformation and mechanical damage. Check the reliability of the fasteners. A breach of the tightness of the components and their joints is fraught with the ingress of exhaust gases into the car interior. Defective components and sections are subject to replacement.
3. 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).
4. Repair of the system should be carried out in the following order:
- a) When removing components, move along the system path in the direction from the exhaust pipe to the engine;
- b) Lubricate the fasteners to be loosened with penetrating oil beforehand;
- c) Prepare the necessary replacement gaskets, hanging loops, clamps and fasteners in advance;
- d) Before installation, lubricate the threaded part of the fastener with anti-seize sealant;
- e) 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. Remember that during operation, the catalytic converter heats up to very high temperatures and then cools down quite slowly, do not rush, wait until the components have completely cooled down;
- f) Before servicing the system, be sure to remove the oxygen sensors with electrical connectors from it.
