6.22. The exhaust system - the general information and removal of components

The exhaust system consists of four sections:

   a) A reception pipe (on some models includes the three-functional catalytic converter).
   b) The forward muffler with a pipe (on some models includes the three-functional catalytic converter).
   c) The intermediate muffler with a pipe.
   d) Back muffler and back exhaust pipe.

Sections of the exhaust system connect among themselves flange connections with the coming-out ends of pipes. Connection of a reception pipe with a final collector is carried out through laying and fastens by means of hairpins and nuts. The reception pipe and connecting pipes between mufflers have an aluminum covering. Mufflers are made of the chromeplated steel.

On models with the catalytic converter the lambda probe is established in a reception pipe. The catalytic converter is installed or in a reception pipe, or in the forward muffler with a pipe.

On the models which are not equipped with system of a turbo-supercharging the double reception pipe is established. On the models equipped with system of a turbo-supercharging, the only reception pipe on the forward end has the knee joining a turbocompressor.

On all models the exhaust system is suspended on all length on rubber support.

Removal

Each section of the exhaust system can be removed individually, but as the back section of system is located over the back stabilizer of cross stability, it cannot be removed in a set with all other system.

For removal of this section of system at first to a poddomkratta a forward or back part of the car, establish it on axial support (address the Section: Poddomkrachivaniye, towage and change of wheels). Alternatively the car can be installed on a viewing hole or on a platform.

Reception pipe (and if is available, the catalytic converter)

If the reception pipe includes the catalytic converter, take care of to dropping the block as it includes a fragile ceramic element.


 PERFORMANCE ORDER

1. On models with the catalytic converter remove a lambda probe (The head Toplivnaya and exhaust systems).
2. Give nuts and divide flange connection between a reception pipe and the forward muffler with a pipe.
3. Unhook rubber support from the car bottom.
4. Give the nuts fixing a reception pipe to a turbocompressor or a final collector (depending on the equipment), then lower a pipe between the engine and a beam of a forward stretcher. Remove laying.

The forward muffler / the catalytic converter with a pipe

On the models equipped with the catalytic converter do not allow falling of the block as it contains a fragile ceramic element.

:

 PERFORMANCE ORDER

1. Give nuts and divide flange connections of the forward muffler with a pipe to a reception pipe and the intermediate muffler with a pipe.
2. Unhook rubber support from the car bottom and lower the forward muffler with a pipe on the earth.

The intermediate muffler with a pipe

 PERFORMANCE ORDER

1. Give nuts / bolts and divide flange connections between the intermediate muffler with a pipe and the forward muffler with a pipe, and also the back muffler with a tail pipe.
2. Unhook rubber support from the car bottom and lower on the earth the intermediate muffler with a pipe.

Back muffler and tail pipe

 PERFORMANCE ORDER

1. Give bolts and divide flange connection between the back muffler with a tail pipe and the intermediate muffler with a pipe.
2. Unhook rubber support from the car bottom and lower the back muffler with a tail pipe on the earth.

Thermal screens

Thermal screens fasten to the car bottom bolts. Each screen can be removed at the same time with removal of the corresponding section of the exhaust system.

Installation into place

Each section is established by N the place as it should be, the return to a removal order taking into account the next moments:

   a) Make sure that from speakers of the ends of pipes in flange connections all traces of corrosion are removed, replace laying between a reception pipe and a final collector / turbocompressor.
   b) Examine rubber support regarding detection of signs of pollution or damage, if necessary replace them.
   c) On models with the catalytic converter establish into place a lambda probe (The head Toplivnaya and exhaust systems).
   d) Make sure that all rubber support are established correctly and that between the exhaust system and a body of the car there is a sufficient gap.
