Manifold Gauge Set Connections
LOW PRESSURE GAUGE HOSE The low pressure hose (Blue with Black stripe) attaches to the low side service port. This service port is located on the accumulator.
HIGH PRESSURE GAUGE HOSE The high pressure hose (Red with Black stripe) attaches to the high side service port. This service port is located on the liquid line between the condenser outlet and the evaporator. On this model, an A/C pressure transducer is also installed onto the liquid line. A/C high side pressures can be read using a DRBIII(R) scan tool. Refer to BODY DIAGNOSTIC PROCEDURES .
RECOVERY/RECYCLING/EVACUATION/CHARGING HOSE The center manifold hose (Yellow, or White, with Black stripe) is used to recover, evacuate, and charge the refrigerant system. When the low or high pressure valves on the manifold gauge set are opened, the refrigerant in the system will escape through this hose.
