Removal and installation of the case of a throttle - petrol models

The prevention in the beginning of section Sbrasyvanie pressure in the power supply system of petrol engines seeSbrasyvanie pressure in the power supply system of petrol engines.

Engines of 1.6 l SOHC

 PERFORMANCE ORDER

  1. Dump residual pressure in the power supply system (Sbrasyvanie of pressure in the power supply system of petrol engines see). Disconnect a negative wire from the battery.

  1. Ослабьте a collar.
  1. Disconnect from a cover of the case of a throttle an inlet air line (do not forget to remove a sealing lining).
  1. Also disconnect from a cover air and vacuum hoses, turn out fixing screws and uncover with a sealing ring the top part of the case of a throttle.
  1. Release clamps disunite contact sockets of electroconducting of the gauge of position (potentiometer) throttle заслонки (TPS), the step-by-step engine and an injector. Take conducting aside.
  1. Disconnect from the throttle case fuel hoses.
  1. Disconnect draught of an accelerator from the hinge on the throttle case.
  1. Disconnect from the throttle case air and vacuum hoses.
  1. Give nuts of fastening of the case of a throttle to the inlet pipeline and remove knot together with a sealing lining. The lining at assemblage is subject to replacement without fail.
  1. In case of need turn out coupling screws (with heads of type TORX) and divide the throttle case on two parts. Remove and will throw out a sealing lining - at assemblage the lining is subject to replacement without fail.
  1. Make sure of absoluteness of cleanliness and dryness of interfaced surfaces, replace a sealing lining and collect the throttle case. Before вворачиванием grease a carving part of fixing screws анаэробным with hermetic. In stages tighten screws with demanded effort.
  2. Make sure of absoluteness of cleanliness and dryness of interfaced surfaces of the case of a throttle and the inlet pipeline, remove all traces of old hermetic from carving parts of nuts and fixing hairpins / of bolts.
  3. Lay on the pipeline a new lining, from above establish the throttle case. Grease a carving part of fixing nuts анаэробным with hermetic. In stages tighten fixture with demanded effort.
  4. Restore initial connection of vacuum and air hoses, connect to the hinge draught of a drive throttle заслонкой.
  5. Connect to the throttle case fuel hoses. Tighten with demanded effort of a nut штуцерных connections. Restore initial connection of electroconducting.
  6. Having replaced a sealing ring, establish into place a cover of the case of a throttle наместо. Screw and reliably tighten screws of fastening of a cover, then connect an inlet air line and vacuum hoses.
  7. Connect a negative wire to the battery. Start the engine and before departure check up power supply system components on presence of signs of development of leaks.

Engines of 1.4 and 1.6 l DOHC

 PERFORMANCE ORDER

  1. Dump residual pressure in the power supply system (Sbrasyvanie of pressure in the power supply system of petrol engines see). Disconnect a negative wire from the battery.
  2. Uncover маслозаливной mouths. Turn out fixing screws and remove a protective casing of the engine. Screw on a place a cover маслозаливной mouths.
  1. Disconnect electroconducting from the gauge of temperature of soaked up air (IAT), disconnect an inlet air line from an air cleaner and the throttle case, - on models Zafira it is required to remove a sealing strip of an impellent compartment and established under a reflector windscreen. For the purpose of providing of access to an inlet air line give fixing nuts and bolts, a panel cover передка.
  1. Disconnect a hose of the valve of a purge of a coal adsorber on the left side of the inlet pipeline.
  1. Release a clamp and disconnect a tip of a cable from the lever of a drive throttle заслонки. Liberate a cover of a cable from a basic arm and take a cable aside.
  2. Turn out fixing bolts and remove the case of a throttle from the pipeline. Remove and will throw out a sealing lining, - at assemblage it is subject to replacement without fail.
  3. Turn the throttle case so that it was possible to steal up to hoses of system of cooling. Put identification labels, ослабьте fixing collars and disconnect both hoses, - at once закупорьте the open ends of hoses for the purpose of minimisation of losses of a cooling liquid.
  4. Disconnect electroconducting from gauge TPS and the step-by-step engine of system of stabilisation of turns of idling, then take the case of a throttle from an impellent compartment.
  5. Installation is made in an order, the return to an order of dismantle of components. Pay attention to following moments:
    1. Before installation of the case of a throttle on a collector make sure of correctness of connection to it of all wires and hoses.
    2. On forget to replace sealing linings (preliminary make sure of absoluteness of cleanliness and dryness of interfaced surfaces), and track that all fixture has been tightened with demanded effort.
    3. Track correctness of a lining and reliability of fixing of all hoses.
    4. In end make adjustment of a cable of gas (Removal, installation and adjustment of a cable of gas - petrol models see).

Engines of 1.8 and 2.0 l

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Uncover маслозаливной mouths. Turn out fixing screws and remove a protective casing of the engine. Screw on a place a cover маслозаливной mouths.
  1. Disconnect electroconducting from the gauge of measurement of weight of air (MAF).
  1. Release clamps and disconnect from an air cleaner and the case of a throttle an inlet air line together with the gauge, - on models Zafira it is required to remove a sealing strip of an impellent compartment and established under a reflector windscreen. For the purpose of providing of access to an inlet air line give fixing nuts and bolts, a panel cover передка.
  1. Release a clamp and disconnect a tip of a cable from the lever of a drive throttle заслонки. Liberate a cover of a cable from a basic arm and take a cable aside. On the models equipped with a control system in the speed, it is necessary to disconnect also приводной a cable tempostatа, - the cable tip is connected to the hinge of the lever of a drive throttle заслонки by means of a lock bracket.
  2. Turn out fixing bolts and remove a basic arm of a cable from the throttle case.
  3. Release fixing collars and disconnect a ventilation hose картера from a cover газораспределительного the mechanism and the throttle case.
  1. Press clamps both throttles of a hose of system of cooling connected to the case, disconnect them, preliminary having weakened collars. At once collect rags traces of the spilt cooling liquid.
  1. Disconnect from the case of a throttle a hose of ventilation of a fuel tank.
  2. On l models 2.0 disconnect electroconducting from the gauge of position throttle заслонки (TPS) and the valve of stabilisation of turns of idling. On engines of 1.8 l disconnect electroconducting from throttle заслонки.
  1. Disconnect from the throttle case all remained vacuum and air hoses, - try to remember an order of connection of hoses. Turn out screws with heads of type TORX and remove the case of a throttle from the inlet pipeline.
  1. Remove and will throw out a sealing lining - at installation the lining is subject to replacement without fail.
  1. Installation is made in an order, the return to an order of dismantle of components. Pay attention to following moments:
    1. Before installation of the case of a throttle on a collector make sure of correctness of connection to it of all wires and hoses.
    2. On forget to replace sealing linings (preliminary make sure of absoluteness of cleanliness and dryness of interfaced surfaces), and track that all fixture has been tightened with demanded effort.
    3. Track correctness of a lining and reliability of fixing of all hoses.
    4. In end make adjustment of a cable of gas (Removal, installation and adjustment of a cable of gas - petrol models see).

Adaptation of the new case of a throttle to ECM is made in the conditions of a car repair shop with application of the special diagnostic equipment.
