2. Regularly inspect the entire system for signs of corrosion, deformation and mechanical damage. Check fastener tightness. Violation of the tightness of the components and their joints is fraught with the ingress of exhaust gases into the passenger compartment, and also leads to difficulty starting the engine and uneven operation at idle and during acceleration.
3. To check the exhaust tract for leaks, start the engine and plug the exhaust pipe with a rag. Determine the location of damage, for which you can use a special spray. Evenly apply the composition to the elements of the exhaust system - in places of leakage, the composition will begin to bubble. Defective components and sections must be replaced.
4. When carrying out work on the exhaust system, the following instructions must be followed:
- a) Lubricate the fasteners to be loosened with penetrating oil or other rust-dissolving agent. Note: If the system is severely corroded, a cutting torch may be required to separate sections of the system (alternatively, you can use a hacksaw or a pneumatic chisel - do not forget to wear safety glasses and gloves;
- b) Prepare in advance the necessary replacement gaskets, new rubber elements of holders, clamps and fasteners, when removing all seals and fastening elements, they must be replaced;
- c) The sealing surfaces of parts to be reinstalled must be cleaned with a wire brush or sandpaper. Lubricate the threaded part of the fastener with an anti-seize sealant before installation;
- d) When installing components, make sure that there is sufficient clearance between the sections of the system and nearby suspension / body elements. Pay special attention to the correct installation and secure fastening of heat shields (with appropriate equipment).
5. When removing or disconnecting the downpipe, it must not be allowed to hang on the flexible section of the pipe (see resist. illustration). Bending the flexible section at an angle of 5-10°and twisting at an angle of±0.5°can lead to its damage and failure. For this reason, when carrying out the relevant work, the downpipe must be fixed with a wire to the rigid elements of the bottom, if necessary, use the help of an assistant.
