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

See the prevention at the beginning of Sbrasyvaniye of pressure in a power supply system of petrol enginesthe section .

Engines of 1.6 l of SOHC

 PERFORMANCE ORDER

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

  1. Weaken a collar.
  1. Disconnect from a cover of the case of a throttle an inlet air line (do not forget to remove sealing laying).
  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 sensor of situation (potentiometer) of a butterfly valve (TPS), the step-by-step engine and an injector. Take conducting aside.
  1. Disconnect from the throttle case fuel hoses.
  1. Disconnect draft 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 sealing laying. Laying at assembly is subject to replacement without fail.
  1. In case of need turn out coupling screws (with TORX type heads) and divide the throttle case into two parts. Remove and will throw out sealing laying - at assembly laying is subject to replacement without fail.
  1. Make sure of absoluteness of purity and dryness of interfaced surfaces, replace sealing laying and collect the throttle case. Before a vvorachivaniye grease a carving part of fixing screws with anaerobny hermetic. In stages tighten screws with demanded effort.
  2. Make sure of absoluteness of purity 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 / bolts.
  3. Lay on the pipeline new laying, from above establish the throttle case. Grease a carving part of fixing nuts with anaerobny hermetic. In stages tighten fixture with demanded effort.
  4. Restore initial connection of vacuum and air hoses, connect to the hinge draft of a drive a butterfly valve.
  5. Connect to the throttle case fuel hoses. Tighten with demanded effort of a nut of shtutserny 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 power supply system components on existence of signs of development of leaks.

Engines 1.4 and 1.6 of l of DOHC

 PERFORMANCE ORDER

  1. Dump residual pressure in a power supply system (see Sbrasyvaniye pressure in a power supply system of petrol engines). Disconnect a negative wire from the battery.
  2. Uncover a maslozalivny mouth. Turn out fixing screws and remove a protective casing of the engine. Screw on a place a cover of a maslozalivny mouth.
  1. Disconnect electroconducting from the sensor of temperature of soaked-up air (IAT), disconnect an inlet air line from an air purifier and the throttle case, - on the Zafira models it is required to remove a sealing strip of an impellent compartment and established under a reflector windscreen. For the purpose of ensuring access to an inlet air line give fixing nuts and bolts, a cover of the panel of a front.
  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 cable tip from the lever of a drive of a butterfly valve. Liberate a cable cover from a basic arm and take a cable aside.
  2. Turn out fixing bolts and remove the throttle case from the pipeline. Remove and will throw out sealing laying, - at assembly 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, weaken fixing collars and disconnect both hoses, - at once закупорьте the open ends of hoses for the purpose of minimization of losses of cooling liquid.
  4. Disconnect electroconducting from the TPS sensor and the step-by-step engine of system of stabilization of turns of idling, then take the throttle case from an impellent compartment.
  5. Installation is made as it should be, the return to an order of dismantle of components. Pay attention to the next moments:
    1. Before installation of the case of a throttle on a collector make sure of correctness of connection to it all wires and hoses.
    2. On forget to replace sealing laying (previously make sure of absoluteness of purity and dryness of interfaced surfaces), and track that all fixture was tightened with demanded effort.
    3. Track correctness of laying and reliability of fixing of all hoses.
    4. In end make adjustment of a cable of gas (see. Removal, installation and adjustment of a cable of gas - petrol models).

L engines 1.8 and 2.0

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Uncover a maslozalivny mouth. Turn out fixing screws and remove a protective casing of the engine. Screw on a place a cover of a maslozalivny mouth.
  1. Disconnect electroconducting from the sensor of measurement of weight of air (MAF).
  1. Release clamps and disconnect from an air purifier and the throttle case an inlet air line together with the sensor, - on the Zafira models it is required to remove a sealing strip of an impellent compartment and established under a reflector windscreen. For the purpose of ensuring access to an inlet air line give fixing nuts and bolts, a cover of the panel of a front.
  1. Release a clamp and disconnect a cable tip from the lever of a drive of a butterfly valve. Liberate a cable cover from a basic arm and take a cable aside. On the models equipped with a control system of speed, it is necessary to disconnect also a driving cable темпостата, - the tip of a cable is connected to the hinge of the lever of a drive of a butterfly valve 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 hose of ventilation of a case from a cover of the gas-distributing mechanism and the throttle case.
  1. Press clamps both throttles of a hose of system of cooling connected to the case, disconnect them, previously having weakened collars. At once collect rags traces of the spilled cooling liquid.
  1. Disconnect from the throttle case a hose of ventilation of a fuel tank.
  2. On models of 2.0 l disconnect electroconducting from the sensor of provision of a butterfly valve (TPS) and the valve of stabilization of turns of idling. On engines of 1.8 l disconnect electroconducting from a butterfly valve.
  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 the TORX type and remove the throttle case from the inlet pipeline.
  1. Remove and will throw out sealing laying - at installation laying is subject to replacement without fail.
  1. Installation is made as it should be, the return to an order of dismantle of components. Pay attention to the next moments:
    1. Before installation of the case of a throttle on a collector make sure of correctness of connection to it all wires and hoses.
    2. On forget to replace sealing laying (previously make sure of absoluteness of purity and dryness of interfaced surfaces), and track that all fixture was tightened with demanded effort.
    3. Track correctness of laying and reliability of fixing of all hoses.
    4. In end make adjustment of a cable of gas (see. Removal, installation and adjustment of a cable of gas - petrol models).

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