Expansion nozzle
The expansion head consists of a measuring orifice and several filters.

Removing
1. Release the pressure in the system. Disconnect the negative battery cable.
2. On four-cylinder models, remove the power steering pump from the side (without disconnecting the tubes) and set it aside. Remove the connections of the refrigerant pipes leading from the refrigerator to the evaporator using a special tool.
3. When you disconnect the tubes, you will see one end of the nozzle inside the tube leading to the evaporator. Remove the nozzle from the tube.
Installation
Installation is carried out in the reverse order of removal.
