A/C Compressor Pressure Relief Valve
WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
An A/C compressor pressure relief valve is incorporated into the compressor A/C manifold and tube to:
- Relieve unusually high refrigerant system discharge pressure buildups. For specifications regarding operating pressure(s), see CLIMATE CONTROL SYSTEM - GENERAL INFORMATION - LS .
- Prevent damage to the A/C compressor and other system components.
- Avoid total refrigerant loss by closing after the excessive pressure has been relieved.
