Core, Service Port Valve: Description
Refrigerant system service ports are used to recover, recycle, evacuate, charge and test the A/C refrigerant system. Unique sizes are used on the two service ports to ensure the system is not accidentally contaminated with refrigerant or by service equipment used for another refrigerant.
The high side service port (1) is located on the liquid line near the left shock tower. The low side service port (2) is located on the suction line near the left shock tower. Both the high side and low side A/C service port valve cores are serviceable.
The protective cap aids in service port sealing and helps protect the refrigerant system from contamination. Remember to always reinstall the protective cap onto the service port when refrigerant system service is complete.
Each of the service ports has a threaded plastic protective cap (6) installed over it from the factory. The service port caps are serviceable items. They are sized and colored according to the refrigerant used in the system.
