Removal and installation of a final collector

SOHC engines

 PERFORMANCE ORDER

  1. Walk on an electroconducting plait from a lambda probe and disunite the contact socket. Liberate an electroconducting plait from all intermediate clamps so that the sensor could be removed together with a collector.
  2. Remove a reception pipe of system of production of the fulfilled gases (see. Systems of release and decrease in toxicity of the fulfilled gases).
  3. Disconnect a sleeve поддачи warmed-up air from a branch pipe of a final collector, turn out fixing bolts and remove a branch pipe.
  4. Remove tips of high-voltage wires from spark plugs of the first, second and third cylinders. Release and remove from a collector thermofilters of candles, - use special head KM-834.
  5. Give nuts of fastening of a collector to a head of cylinders. Remove a collector together with sealing laying and take it from an impellent compartment.
  6. Check hairpins of fastening of a collector on existence of signs of development of corrosion and mechanical damages, damages, in case of need make replacement.
  7. Make sure of absoluteness of purity and dryness of interfaced surfaces, lay new sealing laying.
  8. Establish a collector, screw new fixing nuts and tighten them with demanded effort.
  9. Grease a carving part of thermofilters with high-temperature greasing, wrap screens and tighten them with demanded effort. Establish tips of candle wires.
  10. Establish on a collector a branch pipe, screw fixing bolts and tighten them with demanded effort. Establish a sleeve of supply of warmed-up air.
  11. Attach electroconducting to a lambda probe, track correctness of laying and reliability of fixing of a plait.
  12. Establish a reception pipe of system of production of the fulfilled gases (see. Systems of release and decrease in toxicity of the fulfilled gases).

Engines 1.4 and 1.6 of l of DOHC

 PERFORMANCE ORDER

  1. Uncover a maslozalivny mouth, turn out fixing screws and remove a protective casing of the engine. Walk on an electroconducting plait from a lambda probe and disunite the contact socket. Liberate an electroconducting plait from all intermediate clamps so that the sensor could be removed together with a collector.
  2. Turn out fastening bolts to a collector of a reception pipe of system of production of the fulfilled gases, separate a pipe and remove sealing laying. Turn out three fixing bolts and remove the thermofilter.
  3. Give nuts of fastening of a collector to a head of cylinders. Remove a collector with laying and take it from an impellent compartment.
  4. Establish a collector on the regular place (see above SOHC Engines, item 6 — 8).
  5. Establish new laying between a collector and a reception pipe of system of production of the fulfilled gases, screw fixing bolts and tighten them with demanded effort.
  6. Attach electroconducting to a lambda probe, track correctness of laying and reliability of fixing of a plait.
