Service Gauge Port Valves
WARNING: This page is about a different car, the 2003 Ford Taurus. 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 high pressure liquid line.
The low pressure service gauge port valve is located on the evaporator to accumulator/drier suction line.
The fitting is an integral part of the refrigerant line or component.
- Special couplings are required 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 (19D702) on the service gauge port valves after repairing the refrigerant system.
