To check release system on leakages of the fulfilled gases it is possible as follows: to start the engine, to close an exhaust pipe a rag for short time and to examine system.

In need of replacement of any element of system of release it can appear simpler to remove all system assembled from the car, and then to disassemble it.

1. To unscrew nuts and to disconnect a reception pipe of the exhaust silencer (see fig. System of production of the fulfilled gases) from a final collector.
2. To unscrew bolts of fastening of a reception pipe to an arm on a transmission.
3. To remove rings (1) and (4), and then and all system of release from the car.
4. If pipes of system of release do not manage to be separated, they can be warmed up in a junction a blowtorch.
5. To collect a pipe (12) with a pipe (9) (or the exhaust silencer (10)) and the exhaust silencer (7).
6. To put on a reception pipe hairpins of a final collector, previously having replaced laying. Laying should be established by an otbortovka down. Наживить nuts but not to twist them up to the end.

12. To tighten nuts of fastening of a pipe to a collector and a transmission arm the moment of 30 N · m (3,0 kgfs · м).
13. With effort to take away the exhaust silencer (7) so that the ring of a suspension bracket of the exhaust silencer appeared tense forward the car on 7 mm (distance And).
14. To tighten all carving connections by the moment of 25 N · m (2,5 kgfs · м).
