1. Disconnect a negative wire from the battery.
2. On models with engine D9B without a turbo-supercharging remove a casing воздухораспределителя. In case of need remove also an inlet air line and disconnect a ventilating tube from a jellied mouth of impellent oil (corresponding sections of the present Chapter see).
3. Disconnect a cable of gas from ТНВД (Removal, installation and adjustment of a cable of gas see). Liberate a cable from intermediate clamps and shift it aside where it will not disturb to pipeline/collector removal.
4. On the models equipped with system recycling of fulfilled gases (EGR), disconnect ventilating hoses from valves of a stream and recycling. Release nuts and bolts of fastening of each of valves to the pipeline and a collector remove клапанную assemblage from the engine. Remove sealing linings.
5. On models with a turbo-supercharging release fixing collars and disconnect air hoses from an air line connecting турбокомпрессор with a branch pipe of an air cleaner. Liberate an air branch pipe from the inlet pipeline and take it from an impellent compartment. Закупорьте rags a hose турбокомпрессора, or an aperture actually in assemblage 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 assemblage турбокомпрессора.

6. By means of approaching пруткового a key turn out bolts of fastening of the inlet pipeline; ослабьте, but do not turn out (the pipeline is dismembered), central шестигранный a bolt.
(With a head under прутковый a key (and central шестигранный a bolt (), used on models with a turbo-supercharging, - it it is necessary to weaken bolts of fastening of the pipeline 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 providing of access (especially on models with a turbo-supercharging) remove the inlet pipeline (the previous subsection see).
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 system EGR, 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 release of the fulfilled gases (Systems of decrease in toxicity and release of the fulfilled gases see).
4. On the models equipped турбокомпрессором, remove assemblage of the last (Removal and installation турбокомпрессора see).
5. On some models for the purpose of clearing of working space it is necessary отболтить from a collector резонаторную the chamber.

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

7. Remove assemblage of a collector from a head of cylinders; also remove a sealing lining ().

8. Sometimes fixing hairpins are turned out together with nuts. In their such cases it is necessary to screw back in a head right after collector removals (законтрите on the end of a hairpin two nuts and use them as a bolt head).
