Description And Operation: 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 refrigerant used in the system to ensure the system is not accidentally contaminated with the wrong refrigerant.

The high side service port is located on the A/C liquid line on the right side of the engine compartment, next to the washer bottle fill neck. The low side service port is on the A/C suction line at the bulkhead just below and to the right of the Thermal Expansion Valve (TXV). 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.
