6.20. Removal and installation to the place of the inlet pipeline

Models of system of injection of LH-Jetronic fuel

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire of the battery.
2. Weaken a collar and disconnect the giving hose from the inlet pipeline.
3. According to the instructions provided in the Sections Removal and installation to the place of components of system of injection of fuel (LH-Jetronic) or Removal and installation to the place of components of system of injection of fuel (Trionic) depending on the car equipment, remove a throttle casing from the inlet pipeline. At will it is possible to leave connected hoses and a rope of an accelerator and to shift a casing aside.
4. Remove the fuel highway from the inlet pipeline (address the Sections Removal and installation to the place of components of system of injection of fuel (LH-Jetronic) or Removal and installation to the place of components of system of injection of fuel (Trionic), depending on the equipment)
5. On models with automatic transmission disconnect a rope of the device of decrease in transfer of transmission (kickdown) from a bracket on the inlet pipeline.
6. Release a maslopodayushchy tube of system of a turbo-supercharging from a clip on the inlet pipeline.
7. Disconnect a hose of vacuum strengthening of brakes from the inlet pipeline.
8. Give bolts of fastening of the inlet pipeline to a head of cylinders. Also give the lower bolt from a persistent bar.
9. Remove the inlet pipeline from a head of cylinders. Remove laying.

Installation into place

Installation is into place made as it should be, the return to a removal order. At the same time establish new laying and tighten bolts with the required effort.

Models with a control system of the Trionic engine

Removal

Disconnect a negative wire of the battery.

Top inlet pipeline

 PERFORMANCE ORDER

1. For removal of the top section of the inlet pipeline previously disconnect a plastic sleeve between the case of a throttle and the inlet resonator.
2. Disconnect an idling stabilization valve hose from the gate case.
3. Disconnect a rope of system of a tempostat.
4. Give fixing nuts and remove the throttle case from the inlet pipeline. Put the case aside.
5. Weaken a collar and disconnect a vacuum hose of the regulator of pressure of fuel and system of vacuum strengthening of brakes. Also disconnect a small hose of ventilation of a case.
6. Disconnect EVAP hose (an adsorber purge) from the inlet pipeline, also disconnect the hose going to pressure sensor.
7. Give and remove from a bracket on a wall of the top inlet pipeline the top fixing screws, weaken the lower screws.
8. Otboltite also remove a bracket of a tube of a mouth of the gulf of oil.
9. Give bolts of fastening of the top inlet pipeline to the lower pipeline and remove the top pipeline. Also disconnect idling stabilization valve wires.
10. Examine rubber hoses between the top and lower inlet pipelines, if necessary replace them.

Lower inlet pipeline

 PERFORMANCE ORDER

1. Give bolts of fastening of two racks to the inlet pipeline. Where it is necessary, also weaken the lower bolt / nut of a rack.
2. Disconnect the plug from the cooler temperature sensor.
3. Also remove screws of fastening of tires of grounding (are specified by shooters) on the lower part of an inlet turboprovod.
4. Remove the holder of wires on the inlet pipeline.
5. Disconnect grounding tires from the engine from a distributive chain.

6. Disconnect hoses of giving and return of fuel from the fuel highway and the regulator of pressure.

7. Disconnect the wires going to injectors.
8. Give fixing bolts and remove the lower inlet pipeline from a head of cylinders.
9. Weaken clips and divide two halves of the lower inlet pipeline. Remove connecting hoses.
10. Remove laying from a head of cylinders.

Installation into place

Top and lower inlet pipelines

Installation is made as it should be, the return to a removal order, at the same time establish new laying and tighten fixing bolts with the required effort. Check and if necessary replace hoses and a sealing ring between the case of a throttle and the inlet pipeline. Check adjustment of a tension of a rope of an accelerator (where it is necessary, also a rope of the device of decrease in transfer of automatic transmission (kickdown)) (see the Section Removal, installation into place and adjustment of a rope of an accelerator of this Chapter and Undressed Epiploons of power shafts - the general information).
