- Disconnect the following cables and electroconducting sockets:
- Cable of a drive
of a butterfly valve;
- Socket and TPS sensor clamps;
- IAC valve socket;
- VSV No. 1 sockets and ACIS system No. 2;
- EVAP system VSV socket.
- Turn out three bolts and disconnect a pressure head tube of GUR from the air distributor, its rack and an elevating hook of No. of 1 engine.
- Separate the following connections:
- PCV hose from the PCV valve on a head of the right number of cylinders (1);
- Cable of weight and the grounding tire from the valve of management of supply of air of ACIS (2) system;
- Weight cable from the air distributor (3);
- Vacuum hose of the amplifier of brakes from the air distributor (4);
- Two perepuskny hoses of system of cooling from the case of a throttle (5);
- Hose of a podmeshivaniye of air from the case of a throttle (6);
- Purge hose from a tube on assembly of the valve of EVAP (7) system;
- Two vacuum hoses from the vacuum chamber of ACIS system (8);
- Collar of electroconducting of the engine from assembly of the valve of EVAP (9) system.
Connections which are subject to dismantling
- Remove an elevating hook of No. of 1 engine and an air distributor rack.
- Turn out two bolts, two nuts and remove the air distributor together with laying.
