 REMOVAL

1. Uncover air intake, address the Section Removal and installation of the drive of a screen wiper/cover.
2. Disconnect a hose of the vacuum amplifier of a brake from the inlet pipeline, but not from the amplifier. For removal of a hose application of some effort is demanded.

3. Uncover a jellied branch pipe of the fuel tank. Turn off the screw-driver (shooters on an accompanying illustration) small covers and unscrew the screws which are under them. Remove two plastic facings.

4. Rasstykuyte shtekerny connections of the sensor of oxygen. Rasstykuyte plug of the electromagnetic VANOS valve. Address an accompanying illustration.

5. Remove a shtekerny level and take it aside.

6. Uncover at the inlet pipeline. Turn off a positive reference point (1) and squeeze two clips (arrows on an accompanying illustration). Disconnect a socle.

7. Remove a ventilation branch pipe in the top part of the block of cylinders. Address an accompanying illustration.

 

You do not smoke. There is a danger of ignition! Wipe the following fuel with a rag. Disconnect at first the pipeline of giving (1) (from the filter), then the pipeline of return of fuel (2) at the distributive highway. For this purpose open collars. At assembly collars need to be replaced.

At some models the pipeline of giving is attached directly to the distributive highway. At assembly the sealing ring needs to be replaced with new and to grease with vaseline. There is a fastening of fuel hoses in the form of tightening brackets. In this case the BMW 16 1 050 tool is necessary for removal of brackets. Before installation check a sealing ring. In the presence of damages replace it, address the Section Removal and installation of injectors.

10. Turn off the directing pipe of the index of level.

11. Turn off bolts of fastening and remove a support of the inlet pipeline and a square of a hose of cooling liquid of the inlet pipeline. Address an accompanying illustration.

12. Rasstykuyte shtekerny connection (1) at the valve of ventilation of the fuel tank. Take out the valve upward from the holder. Press a collar (2) and disconnect a hose. Rasstykuyte shtekerny connection of the sensor of temperature of the soaked-up air and the valve of idling at the inlet pipeline. Address an accompanying illustration.

13. Turn off bolts of fastening and remove the inlet pipeline from a head of cylinders.

You watch that any objects did not get to inlet canals. It can lead to heavy damages of the engine.
