Removal and installation of components of an inlet air path

Removal

Petrol models

Astra models

 PERFORMANCE ORDER

  1. Weaken a collar of fastening of an inlet air line to the butterfly valve case. Release latches of clamps of fastening of an air line to the air purifier case, give fixing a screw / nut (and) and take air purifier assembly from an impellent compartment.
  1. Liberate from an arm on the air purifier case the valve of a purge of a coal adsorber.

Hа models with the central injection is required to disconnect also from the air purifier case a vacuum hose and a sleeve of supply of warm air.

  1. In certain cases dismantle of an air purifier is interfaced to a detachment of hoses of system of ventilation of a case and a rassoyedineniye of contact sockets of electroconducting. Sometimes the air line is drawn to an arm by bolts.

Zafira models

 PERFORMANCE ORDER

  1. Remove a sealing strip of an impellent compartment and a cover of the fairing established under bottom edge of a windscreen.
  1. For the purpose of ensuring access to an inlet air line give fixing nuts / bolts and remove the top cover of the panel of a front.
  1. Remove an air purifier and air lines (see above).

2 — the Cover of the case of an air purifier
3 — the Inlet air line
4 — the Sensor of measurement of weight of air (MAF)
5 — the Inlet air line
6 — the Inlet pipeline

7 — the Inlet tube of pressurization
8 — the Connecting hose
9 — Interkuler
10 — a pressurization Hose
11 — a pressurization Sleeve
12 — the Connecting sleeve


 PERFORMANCE ORDER

  1. Release a collar and remove an inlet air line from a back part of the case of an air purifier (see illustrations the Scheme of connection of components of an inlet air path (model of 1.7 l of SOHC) and the Scheme of connection of components of an inlet air path (model of 1.7 l of DOHC)).
  2. Turn out screws (with TORX type heads) fastenings of an arm of an air purifier to a body and remove an air purifier from the engine, - pay attention that in the lower part of the case of an air purifier there is a ledge which at installation should be combined correctly with reciprocal dredging in a mudguard.
  1. The other air lines conducting to a turbokompressor, interkuler and the inlet pipeline can be removed, having weakened the corresponding collars and having turned out fixing screws. Pay attention that in an air line connecting the case of an air purifier and an inlet jack, the sensor of measurement of weight of air (MAF) is built in, - before removal of an inlet air line disconnect electroconducting and remove the sensor.

Models of 2.0 l

2 — the Cover of the case of an air purifier
3 — the Inlet air line
4 — the MAF Sensor
5 — the Inlet air line
6 — a pressurization Sleeve

7 — a pressurization Hose
8 — Interkuler
9 — a pressurization Hose
10 — the Inlet air line
11 — the Connecting sleeve


 PERFORMANCE ORDER

  1. On the Zafira models remove a sealing strip of an impellent compartment and a cover of the fairing established under bottom edge of a windscreen. For the purpose of ensuring access to an inlet air line give fixing nuts / bolts and remove the top cover of the panel of a front.
  1. On all models disconnect a negative wire from the battery, and also electroconducting from MAF sensors and, - if it is established, - temperatures of soaked-up air (IAT).
  1. Disconnect a hose of ventilation of a case from an inlet air line, weaken a collar of fastening and remove an air line assembled together with the sensor of a measuring instrument of weight of air and clean it from under a cowl.
  2. Release clamps, uncover cases of an air purifier and take filtering element, - try to remember the adjusting provision of components. Turn out a fixing bolt and remove the air purifier case, having disconnected it from an inlet air line.
  3. On models with a low-pressure head turbo-supercharging (X20DTL/Y20DTL engines) (see an illustration the Scheme of connection of components of an inlet air path (model of 2.0 l with a low-pressure head turbo-supercharging)) for removal of the air lines conducting to a turbokompressor and the inlet pipeline, previously turn out fixing screws and remove from the engine a plastic protective casing. Release a clamp of fastening of the air line connecting a metal sleeve to the pipeline. Turn out bolts of fastening of a tube to a cover of a head of cylinders, weaken a fixing collar and disconnect a sleeve from a turbokompressor. Remove sleeve assembly with an air line from the top part of the engine and take the sealing ring established between a sleeve and the compressor.
  4. On models with a high-pressure head turbo-supercharging (Y2ODTH engine) (see an illustration the Scheme of connection of components of an inlet air path (model of 2.0 l with a high-pressure head turbo-supercharging)) release fixing collars / give bolts and remove the air lines, connecting an interkuler and the inlet pipeline, and also a turbokompressor sleeve. For removal of a metal sleeve, disconnect from it an air line, then weaken a collar of fastening of a sleeve to a turbokompressor. Turn out a fixing bolt and remove a sleeve from the engine, - pay attention to the sealing ring established.

Installation

All models

Installation is made as it should be, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. Track reliability of a tightening of collars of fastening of air lines. On diesel engines of 2.0 l do not forget to replace a sealing ring, on a joint of a metal sleeve with a turbokompressor (if disconnected a sleeve).
