Removal and installation of the inlet pipeline / final collector

Before starting implementation of the procedure let's the engine cool down completely.


As the inlet pipeline and a final collector have the general laying, their removal is usually made at the same time. All hairpins and bolts have to be moistened before an otdavaniye the getting oil.

Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Moisten with the getting oil of a carving of hairpins of fastening of a final collector and bolts of fastening to a collector of a reception pipe of system of production of the fulfilled gases.
  3. Remove assembly of the air cleaner (The head of the Power supply system and production of the fulfilled gases).
  4. Disconnect cables of gas, the drive of a butterfly valve in the mode kik-Down (only models with AT) and a tempostata (if it is provided) from the throttle case.
  1. Disconnect from the throttle case cables of gas, the drive of a butterfly valve in the mode kik-Down and a tempostat (if it is provided).
  1. Mark and disconnect all vacuum lines and electric sockets from a final collector.
  2. Dump pressure of fuel and disconnect lines of giving and return of fuel from assembly of the fuel highway (The head of the Power supply system and production of the fulfilled gases). Zakuporte open ends of lines.
  3. Weaken a tension of a tape driving belt (The head Nastroyki and routine maintenance).
  4. Remove from the inlet pipeline the pump of system of hydrostrengthening of a wheel with an arm and put aside, without disconnecting from it hoses. Take care of that the pump was installed by a bottom in order to avoid an effluence from it to hydraulic liquid down.
  5. Remove the fuel highway with injectors (The head of the Power supply system and production of the fulfilled gases).
  6. Give nuts/bolts of fastening of the inlet pipeline.

Access to four of elements of fixture of the inlet pipeline (arrow) is possible from above - for an otdavaniye of the remained four elements it is necessary to reach under the pipeline.

  1. Slightly delay the pipeline from the engine, removing from the directing pins on a head of cylinders, then take it from a motive compartment.
  2. Give two bolts and nuts of fastening of a final collector to a reception pipe of system of production of the fulfilled gases and disconnect a pipe from a collector. Throw out a sealing ring.
  3. Remove a final collector.

Installation

 PERFORMANCE ORDER

  1. Carefully smooth out the interfaced surfaces, having removed from them all traces of material of old laying.
  2. If the pipeline/collector is subject to replacement, track that on replaceable from old all fixture was transferred.
  3. Establish new laying on a head of cylinders, having used the directing plugs for its fixing. Establish a final collector and tighten manually nuts.
  4. Freely install the inlet pipeline on a head of cylinders.
  5. Establish fixing bolts of the pipeline and tighten all fixture in the order shown on an accompanying illustration with the required effort. Pay attention that efforts of tightening of extreme bolts differ from others.

Order of tightening of fixture (bolts/nuts) of the inlet pipeline / final collector.

  1. Installation of the remained components is made as it should be, the return to a removal order. In knot of a joint of a reception pipe of system of production of the fulfilled gases and a final collector the new sealing ring is established.

Before connection of fuel lines to the fuel highway replace sealing rings of nipple connections of a bystry joint (The head of the Power supply system and production of the fulfilled gases).

  1. Start the engine and check it for leak of fuel, the fulfilled gases and loss of depression.
