Removal and installation of a cover of the gas-distributing mechanism

L engines 1.4, 1.6 and 1.8

Removal

 PERFORMANCE ORDER

  1. Uncover a maslozalivny mouth, turn out fixing bolts and remove a protective casing of the engine.
  1. Disconnect electroconducting, turn out fixing screws and remove the ignition module (see. Head engine Electric equipment).
  1. Weaken fixing collars and disconnect шлаги case ventilation from the left edge of a cover of the gas-distributing mechanism.
  1. Gradually and having evenly weakened, turn out screws of fastening of a cover.
  1. Uncover the gas-distributing mechanism a head of cylinders. Remove from a cover sealing rings and laying, check their condition, in case of need make replacement.

Installation

 PERFORMANCE ORDER

  1. Make sure of absoluteness of purity and dryness of interfaced surfaces of a cover and a head. Lay in a consolidation cover, having temporarily fixed them konsistentny greasing.


  1. Put a layer of suitable hermetic on an interfaced surface of a head of cylinders around the right covers of beds of camshafts and in semicircular cuts on the left side of molding.
  2. Accurately lay a cover of the gas-distributing mechanism on the regular place, supervising correctness of placement of consolidations. Screw fixing bolts and, moving on a spiral from the center to edges, evenly tighten them with demanded effort.
  3. Restore initial connection of hoses of ventilation of a case — track reliability of a tightening of fixing collars.
  4. Establish into place the ignition module (see. Head engine Electric equipment).
  5. Establish a protective casing of the engine.

Engines of 1.8 l

Removal

 PERFORMANCE ORDER

  1. Remove a protective casing of the engine (see above Engines 1.4, 1.6 and 1.8 of l — Removal).
  1. Weaken fixing collars and disconnect шлаги case ventilation from the left edge of a cover of the gas-distributing mechanism.
  1. Disconnect electroconducting, turn out fixing screws and remove the ignition module (see. Head engine Electric equipment).
  2. Disconnect from the sensor of temperature of cooling liquid the conducting socket.
  1. Disconnect from the thermostat case a hose of an okhladitelny path. Turn out bolts of fastening of a basic arm of a hose to a cover of the gas-distributing mechanism and the inlet pipeline. Weaken a collar and shift a hose aside — prepare for collecting the spilled cooling liquid.
  1. In stages evenly weaken and turn out bolts of fastening of a cover.
  2. Having lifted up, separate a cover from a head of cylinders, remove sealing laying. Check a laying condition, in case of need prepare the replaceable.

Installation

 PERFORMANCE ORDER

  1. Make sure of absoluteness of purity and dryness of interfaced surfaces, lay new laying in dry wiped reception flute of a cover.
  1. Accurately lay a cover of the gas-distributing mechanism on the regular place, supervising correctness of placement of consolidations. Screw fixing bolts and, moving on a spiral from the center to edges, evenly tighten them with demanded effort.
  1. Connect a hose of an okhladitelny path to the thermostat case, fix a hose in an arm on a roof and the inlet pipeline. Check level of cooling liquid, in case of need make the corresponding adjustment (see. Head Routine maintenance).
  1. Connect electroconducting to the temperature sensor.
  2. Restore initial connection of hoses of ventilation of a case — track reliability of a tightening of fixing collars.
  3. Establish into place the ignition module (see. Head engine Electric equipment).
  4. Establish a protective casing of the engine.

Engines of 2.0 l

Removal

 PERFORMANCE ORDER

  1. Remove air purifier assembly (see. Head of the Power supply system and release).
  2. Remove the top section of a cover of a drive of GRM (see. Removal and installation of a cover of a drive of GRM).
  1. Weaken fixing collars and disconnect from a cover of the gas-distributing mechanism шлаги case ventilation.
  1. Turn out fixing bolts and remove a protective casing of spark plugs. Remove from candles protective caps, disconnect and take aside wire VV.
  2. Disconnect and take aside electroconducting from the sensor of provision of a camshaft (CMP).
  3. In stages evenly weaken and turn out bolts of fastening of a cover of the gas-distributing mechanism.
  4. Separate a cover from a head of cylinders, remove laying and take from openings under fixing bolts sealing rings. Attentively examine sealing elements, in case of need make their replacement.

Installation

 PERFORMANCE ORDER

  1. Make sure of absoluteness of purity and dryness of interfaced surfaces, then place sealing laying in a reception flute of a cover. Previously having slightly greased with konsistentny greasing, plant sealing rings in openings under installation of fixing bolts.
  2. Put a layer of suitable hermetic on a surface of a head of cylinders interfaced to a cover around the right covers of beds of camshafts and in semicircular cuts on the left side of molding.
  3. Accurately lay a cover of the gas-distributing mechanism on the regular place, supervising correctness of placement of consolidations. Screw fixing bolts and, moving on a spiral from the center to edges, evenly tighten them with demanded effort.
  4. Restore initial connection of hoses of ventilation of a case — track reliability of a tightening of fixing collars.
  5. Accurately plant tips of VV plugs of wires on spark plugs.
  6. Connect electroconducting to the CMP sensor, establish into place a protective casing of VV of electroconducting, screw and reliably tighten bolts of its fastening.
  7. Lay on a place a plait of electroconducting and strongly tighten a fixing nut.
  8. Establish the top cover of a GRM belt (see above Engines 1.4, 1.6 and 1.8 of l — Installation).
  9. Establish the case of the air filter — see. Power supply system.
