Refrigerant System Service Port Valve

Refrigerant System Service Port Valve

Description

Two refrigerant system service ports are used to recover/recycle/evacuate/charge and test the A/C refrigerant system. Unique sizes are used on the service ports for the R-134a refrigerant system to ensure the system is not accidentally contaminated with R-12 refrigerant or service equipment used for R-12 refrigerant.

The high side service port is located on the A/C liquid line near the front of the right front wheel well. The low side service port is located on the A/C suction line near the A/C expansion valve at the dash panel. Both the high side and low side A/C service port valve cores are serviceable.

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.
