Serviceability check, removal and installation of the case of a throttle

Check

 PERFORMANCE ORDER

  1. On the top part of the case of a throttle the vacuum hose which goes to the sensor of absolute pressure in the pipeline (MAR) is fixed (only models with the 4.0 l engines). Disconnect a hose from the case of a throttle and instead of it connect the vacuum gage.
  1. Disconnect a vacuum hose of the MAR sensor from the throttle case and instead of it connect the vacuum gage (only for the 4.0 l engines).
  1. Start the engine and warm up it up to the normal working temperature (the fan of the cooling system has to be started at least twice). The vacuum gage should not fix depression - make sure of it.
  2. Slightly slightly open a butterfly valve, having exceeded single turns of the engine and make sure available depression on the vacuum gage. If depression is not fixed, check passability of the union. In case of need clean it by means of a cleaner of carburetors.
  3. Stop the engine and make sure of smoothness of the course of a cable of gas and a butterfly valve.
  4. If there are strong indications of jamming, check a cable and an axis of the gate for existence on a bottom of slime and other deposits.
  5. In case of detection of deposits, try to remove them by means of a cleaner of carburetors or other suitable solvent.
  6. If cleaning does not lead to elimination of a problem, replace the throttle case block.

Removal and installation

Before starting implementation of the procedure wait for full cooling of the engine.


 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Remove the air sleeve connected to assembly of the air cleaner and the case of a throttle.
  3. Disunite the electric socket of the sensor of position of the gate (TPS) on the throttle case. Mark and disconnect vacuum hoses from the throttle case.
  4. Disconnect a cable of gas (Section Replacement of a Cable of Gas) and if it is provided, a transmission TV cable (The head Automatic transmission).
  5. Disconnect cooling system hoses from the throttle case. Zakuporte of the line in order to avoid losses of a cooler.
  6. Give four nuts and remove laying of the case of a throttle. Remove all traces of material of old laying from the interfaced surfaces of the case of a throttle and the inlet pipeline.
  1. Give four nuts (shooters) and separate the throttle case from the inlet pipeline (the 5.2 l engine is shown).
  1. You make installation upside-down. Do not forget to replace laying. Make adjustment of a cable of gas and if that is provided, a TV cable (The head Automatic transmission). Check cooler level, in case of need make having added (The head Nastroyki and routine maintenance).
