1. Disconnect a negative wire from the battery.
2. On models with the D9B engine without a turbo-supercharging remove an air distributor casing. In case of need remove also inlet air line and disconnect a ventilating tube from a jellied mouth of impellent oil (see appropriate sections of the present Chapter).
3. Disconnect a gas cable from TNVD (see. Removal, installation and adjustment of a cable of gas). Liberate a cable from intermediate clamps and shift it aside where it will not disturb pipeline/collector removal.
4. On the models equipped with system of a retsirkulyatsiya of fulfilled gases (EGR), disconnect ventilating hoses from stream and retsirkulyatsiya valves. Release nuts and bolts of fastening of each of valves to the pipeline and a collector remove klapanny assembly from the engine. Remove sealing laying.
5. On models with a turbo-supercharging release fixing collars and disconnect air hoses from an air line connecting a turbokompressor to a branch pipe of an air purifier. Liberate an air branch pipe from the inlet pipeline and take it from an impellent compartment. To Zakuporta rags a turbokompressor hose, or an opening actually in assembly of the last if the hose is completely removed. Release a fixing collar and disconnect an air hose of the built-in cooler (Intercoоler) from turbokompressor assembly.

6. By means of a suitable prutkovy key turn out bolts of fastening of the inlet pipeline; weaken, but do not turn out (the pipeline is dismembered), the central six-sided bolt.
Bolts of fastening of the pipeline (with a head under a prutkovy key (And) and the central six-sided bolt (In), used on models with a turbo-supercharging, - it should be weakened only); the engine is for descriptive reasons removed from the car

7. Remove the pipeline from a head of cylinders.

1. For the purpose of ensuring access (especially on models with a turbo-supercharging) remove the inlet pipeline (see the previous subsection).
2. If the inlet pipeline does not act in film, execute the procedures described in subsection "The inlet pipeline - Removal", subitem 1 — 4. On the models equipped with EGR system, execute also the procedure described in subsection "The inlet pipeline - Removal", item 5.
3. On models without a turbo-supercharging disconnect from a final collector a reception pipe of system of production of the fulfilled gases (see. Systems of decrease in toxicity and production of the fulfilled gases).
4. On the models equipped with a turbokompressor, remove assembly of the last (see. Removal and turbokompressor installation).
5. On some models for the purpose of clearing of working space it is necessary отболтить from a collector the rezonatorny chamber.

6. Give six nuts of fastening of a final collector and remove from hairpins remote plugs.

7. Remove collector assembly from a head of cylinders; also remove sealing laying (and).

8. Sometimes fixing hairpins are turned out together with nuts. In such cases they should be screwed back in a head right after collector removal (законтрите on the hairpin end two nuts and use them as a bolt head).
