Service Gauge Port Valves
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.
The high-pressure service gauge port valve is located on the A/C receiver drier manifold and tube assembly.
The low pressure service gauge port valve is located on the manifold of the A/C compressor manifold and tube assembly at the A/C compressor.
The fitting is an integral part of thee refrigeration line or component.
- Special couplings are necessary for both the high side and low side service gauge ports.
- A new Schrader-type valve core can be installed if the seal leaks.
- Always install the A/C charging valve cap on the service gauge port valves after repairing the refrigerant system.
