Service Port Valve Core: Description
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
Two refrigerant system service ports are used to charge/recover/recycle/evacuate and test the air conditioning refrigerant system. Unique service port coupler sizes are used on the R-134a system to ensure the refrigerant system is not accidentally contaminated with R-12 refrigerant or refrigerant system service equipment.
The high side service port is located on the receiver/drier. The low side service port is located on the suction line, near the right strut tower. Both the high side and low side A/C service port valve cores are serviceable. See Fig 1.
Each of the service ports has a threaded plastic protective cap installed over it from the factory. After servicing the refrigerant system, always reinstall both of the service port caps.
