The general description and replacement of components of final system

On new cars the exhaust system consists only of two parts; a reception pipe (and каталитический the converter where it is applied) and the rest of system consisting of the central muffler, a back pipe and the muffler. The reception exhaust pipe in a back part has фланцевое connection with a lining or конусное connection.
The back part of final system settles down above a back suspension bracket, however with the muffler it is possible to replace an intermediate part and a back pipe separately, having sawn off them ножовкой. The system on all length is supported rubber подвесами.

To remove a system part, at first поддомкратьте a forward or back part of the car, and establish it on axial props. Alternatively, place the car on a viewing hole. Where is available, remove the bottom guard of the engine.

RECEPTION PIPE

REMOVAL

1. Where it is applied, turn away a reception pipe from an arm. 2. Turn on and remove nuts/bolts, fastening фланцевое connection of a reception pipe with a collector or turbocharger (where is available), and remove a lining. 3. Turn on and remove flange bolts, and disconnect a reception pipe from каталитического the converter or an intermediate part. Take a pipe from under the car.

THE KATALITICHESKY CONVERTER

REMOVAL

1. Turn on and remove a flange bolts the appendix of a reception pipe to каталитическому to the converter and remove a lining. 2. If the factory back part is established, it is necessary for sawing off for catalytic the converter. 3. Having cut an intermediate pipe, get каталитический the converter from under the car.

INTERMEDIATE PIPE (AND THE MUFFLER WHERE IT IS APPLIED)

REMOVAL

1. On models without каталитического the converter, turn on and remove bolts of a flange connecting a reception pipe with intermediate and remove a lining. 2. On models with catalytic the converter, remove каталитический the converter as it is described in paragraphs above. 3. If the factory back part is established, it is necessary for sawing off. 4. Having cut an intermediate pipe, get it from under the car. 5. If the back part consists of two half, turn away a bolt and pull together the tightening plug back, then unhook rubber подвесы and get an intermediate part from under the car.

BACK PIPE AND THE MUFFLER

REMOVAL

1. If the factory back part is established, follow the instructions presented above. 2. If the back part consists of two half, turn away a bolt and pull together the tightening plug forward on an intermediate part, then unhook rubber подвесы and get a back pipe and the muffler from under the car.

ТЕПЛОИЗОЛЯЦИОННЫЕ BOARDS

REMOVAL

1. Teploizoljatsionnye boards are attached to the bottom by various nuts and bolts. Each board can be removed only after removal of a corresponding part of final system. If the board acts in film to get access to a component located behind it, in certain cases enough to turn away fixing nuts and-or bolts, and simply to lower a board, without disturbing an exhaust system. Otherwise remove a part of final system as it has been described earlier.

INSTALLATION

1. Each part is established in sequence, return to removal, paying attention to the following: a) Be convinced that from flanges all traces of corrosion have been removed, replace all necessary linings. b) Examine rubber подвесы on damage or pollution signs, replace as required. At connection of intermediate and back parts, put a small amount герметизирующей pastes for final system (Renault recommends Sodicam) on an internal surface of the plug to provide tight consolidation. Place tightening a plug bolt vertically on a left-hand side of a pipe and reliably tighten a nut, yet will not hear click; tightening the bolt has a flute for maintenance of a correct inhaling of a nut (the inhaling moment approximately 25 Nanometers) d) To a tightening of connections of final system be convinced that all rubber подвесы are correctly located, and there is an admissible backlash between the bottom of the car and final system.
