A/C Compressor Pressure Relief Valve
WARNING: This page is about a different car, the 2002 Mazda B4000, 2002 Mazda B3000, and 2002 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
An A/C compressor pressure relief valve is incorporated in the manifold and tube assembly to:
- Relieve unusually high refrigerant system discharge pressure buildups, (3103 kPa [450 psi] and above).
- Prevent damage to the A/C compressor and other system components.
- Avoid total refrigerant loss by closing after the excessive pressure has been relieved.
