How to replace the A/C expansion valves in an air conditioning system on Saturn Outlook?

There are multiple methods for converting high-pressure liquid refrigerant to lower-pressure vapor in air conditioning systems. This conversion occurs as the refrigerant passes through the evaporator, cooling the airflow for delivery to the vents. One common approach is to use a controlled orifice, which is often a removable component in the AC pipes at the firewall. However, the models covered in this manual utilize an A/C expansion valve (TXV) that serves the same purpose as a controlled orifice. To remove the front expansion valve, the air intake duct and windshield washer fluid heater (if present) must be taken out, followed by disconnecting the refrigerant lines from the TXV. If necessary, the power brake booster vacuum line should be disconnected and moved aside for better access. The TXV can then be removed by taking out the two bolts securing it to the firewall. For the rear auxiliary expansion valve, the passenger rear wheel and inner fender splash shield need to be removed first. From underneath the rear of the vehicle, the refrigerant lines should be disconnected from the rear auxiliary HVAC module by removing a single nut. Finally, the two bolts securing the TXV to the vehicle can be removed, allowing the valve to be taken out. When installing, all connections should be assembled with new O-rings or seals, lightly lubricated with R-134a refrigerant oil. The system should then be evacuated, charged, and leak tested.

Saturn Outlook A/C Expansion Valve

The job of the Saturn Outlook A/C Expansion Valve is to control the flow of refrigerant so that the cabin temperature reaches and stays at the desired setting without wasting energy. Located at the evaporator inlet, the A/C Expansion Valve converts high pressure liquid refrigerant into low pressure mist to allow the evaporator quick heat absorption. The A/C Expansion Valve, which opens and closes according to temperature and pressure readings, meters just enough refrigerant to prevent evaporator freeze up while maintaining strong cooling. This is done by making a small internal orifice. The A/C Expansion Valve controls the amount of refrigerant that gets into the vehicle's evaporator based on the temperature of the air to and from the evaporator. When sensors indicate warm air, it widens; when the evaporator cools, it narrows. This constant adjustment keeps the compressor from suffering from liquid slugging caused by too much, too fast refrigerant and allows air to flow smoothly from the dash vents. The Saturn Outlook, throughout all model years, relied on the same thermal A/C Expansion Valve rather than an older fixed orifice tube. This gives more precise control and helps extend component life. Owners of the Saturn Outlook will notice this benefit while on long summer drives.

Each OEM Saturn Outlook A/C Expansion Valve we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
