3.19. Check of a condition of components of system of production of the fulfilled gases


  1. Having waited for full 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 with a cut of an exhaust pipe. For providing free access under the car hang out it above the ground, or tire out on a platform / a viewing hole.

Remember that the catalytic converter(s), - depending on a complete set, - can remain warmed much longer than other components of system of release, - be careful!

  1. Check sections of system and the place of their joints for existence of signs of development of leak of the fulfilled gases, traces of corrosion and mechanical damages, make sure of reliability of tightening of fixture, estimate a condition and reliability of fastening of arms and rubber suspensions of components of system.
  2. Estimate reliability of tightening of elements of fastening of thermoprotection covers. In case of need make the corresponding corrections.
  3. At the same time examine the vehicle bottom on existence of holes, traces of development of corrosion, a divergence of the welded seams and other damages allowing the fulfilled gases to get into interior of the car. Seal all found openings with silicone sealant or usual body filling.
  4. The roar and many other extraneous noises during the movement often are a consequence of weakening of fixture of components of system of release, or shift of its sections. Attentively examine the corresponding elements, the muffler and the catalytic converter, checking whether they adjoin to elements of the bottom or a suspension bracket. In case of need replace details of support of a suspension bracket of system.
  5. On appearance of a cut of an exhaust pipe it is possible to estimate the general working condition of the engine with high degree of reliability. The consistence and color of the deposits covering the end of a pipe 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, the engine, together with a power supply system was formed, needs control.
