Front Service Port Valve Core - Description






DESCRIPTION





Two refrigerant system service ports are used to recover/recycle/evacuate/charge and test the front 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 (1) for the front A/C system is located on the A/C liquid line (2), near the front expansion valve (4), at the dash panel. The low side service port (5) for the front A/C system is located on the A/C suction line (3), also near the front expansion valve. Both the high side and low side A/C service port valve cores are serviceable.

Each of the front A/C system service ports has a threaded plastic protective cap installed over it from the factory. After servicing the front refrigerant system, always reinstall both of the service port caps.
