1. Having waited complete cooling of system of production of the fulfilled gases (not less than three hours later after an engine stop), attentively examine all its components, beginning from a flange of fastening of a reception pipe to a final collector and finishing a cut of an exhaust pipe. For providing a free access under the car hang out it by means of the winch, or tire out on a platform or a viewing hole.

2a. Check system sections on existence of signs of leakages of the fulfilled gases (see accompanying illustrations), traces of corrosion and mechanical damages. |
|
|
2b. Check places of their joint. |

2c. Make sure of reliability of a tightening of fixture. Check a condition and reliability of fastening of arms and rubber подвесов system components (see an accompanying illustration). |
3. At the same time examine the car bottom on existence of holes, traces of development of corrosion, a divergence of welded seams and the other damages allowing fulfilled gases to get into salon of the car. Zagermetiziruyte all found openings silicone or a usual body shpaklevka.
4. The roar and many other extraneous noise during movement often appear a consequence of weakening of fixture of components of system of production of the fulfilled gases or shifts of its sections. Attentively check a condition of arms and подвесов, pull pipes, the exhaust silencer and the catalytic converter, whether checking they adjoin to bottom or suspension bracket elements. In case of need replace components of support of system.
5. On an external condition of a cut of an exhaust pipe it is possible to estimate the general working condition of the engine qualitatively. The consistence and color covering the end of a pipe of deposits allow to reveal violations of adjustments of the engine. If the pipe is covered with black sazhisty deposits, or on it the raid of whitish color was formed, the engine needs control together with a power supply system.
