|
|
|
- Details of installation of an air inlet (1) of an inlet air path.
|
- Turn out two fixing bolts in a forward part of an air inlet.

- Release a collar of fastening of an air inlet to the air cleaner.
- Installation is made upside-down, - track reliability of tightening of a fixing collar.
|
|
First (verkhnepotochny) rezonatorny camera
|
|
- The first (verkhnepotochny) resonator is installed directly ahead of assembly of the air cleaner and connected to a back part of an air inlet by a by-pass hose.
- Disconnect from the rezonatorny camera by-pass a hose.
- Release two fixing nuts and remove the resonator.
- Installation is made upside-down.
|
|
Air cleaner
|
|
- Remove an air inlet.
- Release a fastening collar to the air cleaner of an air duct of an inlet air path.
- Having released a spring clamp, disconnect an electrical wiring from the MAF sensor.
- Turn out a fixing bolt, release two nuts and remove assembly of the air cleaner.
- Turn out a fixing bolt and remove a basic arm of the air cleaner from a mudguard of an arch of the left wheel.
- Installation is made upside-down, - track observance of requirements of Specifications of the Head of the Power supply system, management of engine/decrease in toxicity of the fulfilled gases and production of the fulfilled gases to efforts of tightening of carving fixture.

|
MAF sensor
|
|
- The MAF sensor is built in in the branch pipe included in a sleeve of an air duct of an inlet air path directly after the air cleaner (see
the illustration Structure of the Inlet Air Highway of the Petrol Engine).
|
|
- Disconnect an electrical wiring from the MAF sensor.
|
- Turn out two fixing bolts it a basic arm, release two fixing collars and remove a branch pipe with the sensor which is built in in it.
- Installation is made upside-down, - track correctness of inclusion of a branch pipe in an air path, - marking in the form of an arrow has to specify in the direction of the movement of a stream of air (to the throttle case).
|
|
Second (nizhnepotochny) rezonatorny camera
Details of installation of components of an inlet air path
|
|
- Release a fixing collar, turn out a fixing bolt and remove assembly of the resonator.
|
|
IAC valve
|
|
- The valve is installed on inlet section of the case of a throttle (see
the illustrations Structure of the Inlet Air Highway of the Petrol Engine).
- Switch off ignition and disconnect an electrical wiring from the IAC valve.
- Turn out two fixing bolts and remove the valve from an inlet air duct.
- Carefully smooth out the interfaced surfaces of the valve and inlet section of the case of a throttle.
- Installation is made upside-down, - do not forget to establish NEW sealing laying.
|
|
TPS
Throttle case
|
|
Replacement of the case of a throttle should be made assembled with TPS. |
|
|
- The case of a throttle is located at the end of an air duct of an inlet air path and is connected to the air distributor of the inlet pipeline (see
the illustration Structure of the Inlet Air Highway of the Petrol Engine). The case of a throttle needs replacement at identification of mechanical damages, and also in case of jamming or violation of the course of butterfly valves.
- Switch off ignition.
- Merge cooling liquid (see the Head the Current leaving and service).
- Disconnect an electrical wiring from TPS.
- Release a fastening collar to inlet section of the case of a throttle of an air duct of an inlet air path. Disconnect four ventilating hoses.
- Disconnect an electrical wiring from the MAF sensor.
- Release a collar of fastening of an inlet air duct to the air cleaner.
- Turn out a bolt of fastening of a basic arm and remove an inlet air duct.
- Turn out bolts of a basic arm of a cable of the drive of butterfly valves, disconnect a driving cable and take him aside.
- Disconnect two hoses of a cooling path from the throttle case.
- Release bolts and nuts of fastening of the case of a throttle to the air distributor of the inlet pipeline.
- Remove the case of a throttle and its sealing laying.
- Carefully smooth out the interfaced surfaces of the case of a throttle and the air distributor.
- Installation is made upside-down, - do not forget to replace sealing laying, track observance of requirements of Specifications of the Head of the Power supply system, management of engine/decrease in toxicity of the fulfilled gases and production of the fulfilled gases to efforts of tightening of carving fixture.
|
|
- After connection of a driving cable make sure that butterfly valves are completely closed then measure the size of a free wheeling of a cable. The required value makes 1.0 ÷ 3.0 mm, - in case of need make the corresponding adjustment.
|
|
|
Air distributor
The air distributor connects the throttle case to the inlet pipeline.
Details of installation of the air distributor
|
|
- Turn out two bolts of fastening of an inlet air duct.
- Release a collar of fastening of an inlet hose of the case of a throttle.
- Disconnect four ventilating hoses on the throttle case.
- Disconnect an electrical wiring from the MAF sensor.
- Release a collar of fastening of an inlet air duct to the air cleaner.
- Turn out a bolt of a basic arm of an inlet air duct.
- Turn out bolts of fastening of the MAF sensor.
- Remove assembly of an inlet air duct.
- Turn out bolts of a basic arm of a cable of the drive of a butterfly valve.
- Disconnect a cable of the drive of a butterfly valve.
- Merge cooling liquid (see the Head the Current leaving and service).
- Disconnect a vacuum hose of the brake amplifier.
- Disconnect an electrical wiring from TPS.
- Disconnect two hoses of a cooling path from the throttle case.
- Release a fixing collar and disconnect a hose of system of stabilization of idling. Release a collar of fastening of an air hose to the air route.
- Disconnect from the air distributor шлаг PCV.
- Disconnect the vacuum line from the fuel pressure regulator.
- At the corresponding complete set disconnect vacuum lines of a tempostat from the air distributor.
- Disconnect an electrical wiring from the IAC valve.
- Turn out two bolts and fastenings of a basic arm to the air distributor.
- Turn out two top bolts of fastening of a basic arm of the inlet pipeline.
- Hang out the car above the ground.
- Turn out two lower bolts of a basic arm of the inlet pipeline.
- Lower the car on the earth.
- Disconnect an inlet hose of a heater.
- Disconnect a vacuum hose from a vacuum tube.
- Give three fixing bolts and nuts and remove the air distributor.
- Disconnect a vacuum hose from the top part of the case of a throttle.
- Remove the throttle case.
- Give two fixing bolts and nuts and remove the electromagnetic valve with a basic arm.
- Turn out fixing bolts and remove the IAC valve with a basic arm.
- Installation is made upside-down.
- In conclusion fill the cooling system (see the Head the Current leaving and service), start the engine and check it for existence of signs of development of leaks.
