Disconnect a tube of system of recirculation of the fulfilled gases 5 from the valve of recirculation of the fulfilled gases.

Fig. 2.47. The dismantled components of system of an admission

Remove the amplifier of an inlet collector 1.

Fig. 2.48. Amplifier of an inlet collector 1

Remove an inlet collector 1 with a throttle branch pipe 2 and a tube of system of recirculation of the fulfilled gases 3 from a head of the block of cylinders, and then laying of a collector (fig. 2.48).

Installation is made as it should be, the return to removal, except for the following.

Use new laying of an inlet collector and laying of a tube of system of recirculation of the fulfilled gases.

Fig. 2.49. Nuts of fastening of an inlet collector

Tighten bolts 1 and nuts the 2nd nominal force of an inhaling (fig. 2.49).

Moment of an inhaling of a bolt and nut of an inlet collector (a): 25 N · m.

Make sure that all parts removed when dismantling are established into place.

Establish all necessary details which were not established yet.

Adjust a gap in the drive of a butterfly valve.

Fill the cooling system.

After completion of installation, turn the ignition switch in position of ON, but do not start the engine, and be convinced of lack of leak of fuel.

At the end start the engine and be convinced of lack of leak of cooling liquid.
