Removal and installation of system of production of the fulfilled gases

Cars to 9/89 g вып.

1 — a reception pipe of the exhaust silencer
2 — forward and average exhaust silencers
3 — the back exhaust silencer
4 — a back pipe of the Sedan model
5 — a back pipe of the Compact model
6 — differences: diesel model

7 — laying to (replace)
8 — differences: catalyst
9 — the catalyst
10 — rubber fastening to grease (high-temperature greasing)

Cars from 10/89 g вып. (option with the catalyst), a forward drive

1 — a reception pipe of the exhaust silencer
2 — the catalyst
3 — the average exhaust silencer
4 — the back exhaust silencer
5 — differences: diesel engine

6 — laying to (replace)
7 — a final collector
8 — the thermal screen
9 — rubber fastening
10 — a lambda probe

to grease (high-temperature greasing)

System removal in a set will be described. However each detail of final system can be replaced separately. It is obligatory to replace rubber bufer and laying, and also fastening nuts.



    To lift the car. To cover all bolts and nuts of final system, and also a place of connections with means corroding a rust. To wait some time while means will work. To weaken flange bolts on the back exhaust silencer and to shift back. To disconnect the back exhaust silencer from rubber fastening and to remove. To unscrew an average exhaust pipe, to disconnect a rubber support and to remove.

Not to subject the catalyst to influence of blows at removal and installation as it can be damaged because of it. Not to allow falling and not to strike blows with a hammer.

    To unscrew a reception pipe of the exhaust silencer from a final collector.


For simplification of weakening of bolts and nuts of an exhaust system further it is recommended to cover them with high-temperature paste, for example Liqui Moly LM-508-ASC.


    If the pipes which were in the use of an exhaust system are established, before connection it is necessary to clear the ends of pipes of the deposit remains an emery paper.

The exhaust system at models with the catalyst should be the especially tight. Therefore all consolidations should be replaced new, differently there will be shortcomings of dynamic characteristics.

    To establish a reception pipe of the exhaust silencer on a final collector and evenly to tighten new nuts, without tightening while it is final. To screw together exhaust pipes and exhaust silencers. Before an inhaling of bolts to level pipes and exhaust silencers and to attach to rubber fastenings. To watch thus sufficient distance to the bottom (at least 25 mm). To tighten fastening flanges in front back with the ordered moments of an inhaling.

Not to tighten bolts too strongly, differently laying will be flattened that will lead to a leakage.

    To lower the car.
