Removal and installation of the accumulator (store) of the air conditioning system

The air conditioning system constantly is under pressure. Do not weaken nipple connections of lines and do not disconnect systems, any of components, before carrying out its discharge. Coolant has to be extorted from system in special compensatory and recovery ERA-blok at the station of dealer office or in a specialized workshop of car service. At a rassoyedineniye of lines of system surely put on goggles!


 PERFORMANCE ORDER

  1. Make a discharge of the air conditioning system (see the prevention above).
  2. Disconnect a negative wire from the battery.
  3. Disunite the electric socket on the sensor switch pressure switch in the top part of the accumulator which is located from the passenger party of the car, near a wheel arch.
  1. Disconnect the sensor switch of pressure of inclusion of a clutch coupling from the accumulator.
  1. Disconnect the line of absorption from the compressor, previously отболтив it.

It is not necessary to disconnect refrigerator lines from the accumulator - they have to be replaced together with the accumulator.

  1. Zakuporte open unions in order to avoid hit in system of moisture and dirt.
  2. By means of the special tool (see the Section Removal and installation of the heat exchanger of a heater) disconnect the line from the accumulator where it passes through a partition of a motive compartment to the evaporator. Weaken a coupling bolt of a fixing arm and remove the accumulator together with the lines connected to it.
  3. If the accumulator is replaced, remove with old Schröder's valve (under pressure sensor switch) and pour out oil in measured capacity, having remembered its quantity. Add the same amount of oil (which is coordinated on type with R-134a), plus one more ounce (28.35 g) in the new accumulator.
  4. You make installation upside-down.

At assembly in each sprung joint it has to be established on the sealing ring suitable for the use in the systems filled with oil like R-134a.

  1. Drive away the car in the same workshop where air conditioning system discharge was made. Make its depletion, charging and check on leaks here.
