Replacing the filter element of the receiver-drier

In case of repair or replacement of elements of the air conditioning system, if the air conditioning system was in the open state (some units were removed, pipelines were destroyed, etc.), filter element of the receiver-drier (cartridge) must be replaced. Without this, after filling the system, the refrigerant will not dry out and acids may form inside the system, which will destroy the parts of the air conditioner from the inside.

You will need: 10 key, TORX T70 key.

1. Install the car on an inspection ditch. Disconnect the wire from the negative terminal of the battery.

2. Remove the refrigerant from the air conditioning system (see Removing Refrigerant from the Air Conditioning System).



3. Remove the engine mudguard (see Removal and installation of mudguard and crankcase protection).



4. Remove the screw plug at the bottom of the receiver housing.


5. Remove the old cartridge from the receiver housing.

WARNING: If aluminum or plastic particles are found on the surface of the cartridge, then the pump part of the compressor has collapsed.

Replacing only the cartridge in this case will not give a positive result. You will need to replace the compressor with flushing the system. This rather time-consuming procedure can only be performed in a specialized service center using special technological equipment.



6. Open the sealed package and install a new cartridge in the receiver. Close the screw plug.

WARNING: When purchasing a new filter element (cartridge), make sure it was stored in sealed packaging. A filter element that has been stored unpackaged is unusable, even if it is brand new and clean.

7. Charge the air conditioning system with refrigerant at a specialized auto air conditioner service center.
