In the article, we will look at how to bleed the refrigerant from the system, replace the tube seal rings and parts, and replace the cabin air filter element

Removing refrigerant from the air conditioning system

If you need to perform work on the depressurization of the system, then you need to remove the refrigerant from the system

Refrigerant must be discharged from the system either outdoors or in a well-ventilated area.

The refrigerant at atmospheric pressure changes from a liquid state to a gaseous state

It is necessary to release the refrigerant from the system slowly, in a thin stream.

Bleeding off the refrigerant may cause some oil to splatter.

Therefore, you need to put a rag near the bleed valve.

O-ring replacement

O-rings in the joints should only be used those intended for the air conditioning system, regardless of the fact that the dimensions are the same

When disassembling a connection, you need to determine the design of the fitting in order to correctly select the type and size of o-rings

Before installation, make sure that neither the O-ring "A" nor the fitting "B" is damaged or deformed

When installing the O-rings, they must be lubricated with oil for the air conditioning compressor

Changing the cabin air filter element

A paper filter element is installed in the interior ventilation system

It is recommended to replace the filter element every 15,000 km of the car.

But in dusty areas, you need to replace the filter element as often as possible.

The amount of air supplied through the heater and air conditioner depends on this.
