4. Disconnect the electric socket from the sensor of provision of a throttle.

5. Weaken collars and disconnect cooling hoses. In order to avoid loss of a cooler stop up a hose.
6. Only on models of 1985 of the issue disconnect air hoses from the valve of additional air.
7. Where it is necessary, pick up the turbocompressor pressure phone.
8. Disconnect a vacuum hose from the throttle case.
9. Give 3 fixing nuts and remove the throttle case from the inlet pipeline.
