Q:
How to remove the Expansion Valve on Cadillac Escalade? Posted by Customer
A:
There are various methods used by air conditioning systems to convert high-pressure liquid refrigerant to lower-pressure vapor, with the conversion occurring at the air conditioning evaporator. As the refrigerant passes through the evaporator, it chills and cools the airflow for delivery to the vents. This conversion is typically achieved through a sudden change in tubing size, and in many vehicles, there is a removable controlled orifice in one of the refrigerant lines at the firewall. Additionally, some models utilize an A/C Expansion Valve to accomplish the same function as a controlled orifice for both the front and auxiliary air conditioning systems. To remove the A/C Expansion Valve, the air conditioning system must be discharged, and then the refrigerant lines can be disconnected from the A/C Expansion Valve at the firewall or rear air conditioning unit. The valve can then be removed by taking out the two bolts securing it, and the four O-rings should be replaced. The installation process is simply the reverse of the removal.

How to Remove and Install a Expansion Valve on Pontiac G5? Posted by Customer
A:
There are various methods used by air conditioning systems to convert high-pressure liquid refrigerant to lower-pressure vapor. This conversion occurs at the air conditioning evaporator, which is cooled as the refrigerant passes through it, thereby cooling the airflow that is delivered to the vents. Typically, this conversion is achieved through a sudden change in tubing size, although some vehicles may have a removable controlled orifice in one of the refrigerant lines at the firewall. However, the models covered in this manual utilize an A/C expansion valve that serves the same purpose as a controlled orifice. To remove the A/C expansion valve, the air conditioning system must be discharged first, followed by the removal of the nut and disconnection of the refrigerant lines from the A/C expansion valve at the firewall. Then, the two bolts securing the valve can be removed, and the valve itself can be taken out. The installation process is the reverse of the removal procedure.
