Service Gauge Port Valves
WARNING: This page is about a different car, the 2004 Ford Ranger. 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 compressor manifold and tube assembly (3.0L and 4.0L engines) or the compressor-to-condenser discharge line (2.3L engine only).
The low-pressure service gauge port valve is located on the suction accumulator.
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.
- The Schrader-type valve core can be replaced if the seal leaks.
- Always install the A/C charging valve cap (19D702) on the service gauge port valves after repairing the refrigerant system.
