When servicing the A/C system, a R-134a refrigerant recovery/recycling/charging station that meets SAE standard J2210 must be used (1). Contact an automotive service equipment supplier for refrigerant recovery/recycling/charging equipment. Refer to the operating instructions supplied by the equipment manufacturer for proper care and use of this equipment.
A manifold gauge set (1) may be needed with some recovery/recycling/charging equipment. The manifold gauge set should have manual shut-off valves (2 and 6), or automatic back-flow valves located at the service port connector end of the manifold gauge set hoses (4 and 5). This will prevent refrigerant from being released into the atmosphere.
Manifold Gauge Set Connections
RECOVERY/RECYCLING/EVACUATION/CHARGING HOSE- The center manifold hose (Yellow, or White, with Black stripe) (3) 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.
HIGH PRESSURE GAUGE HOSE - The high pressure hose (Red with Black stripe) (4) attaches to the high side service port. This service port is located on the A/C liquid line next to the left shock tower. On this model, an A/C pressure transducer is also installed on the liquid line. A/C high-side pressures can be read using a scan tool. Refer to 9 - Engine Electrical Diagnostics for more information.
LOW PRESSURE GAUGE HOSE -
The low pressure hose (Blue with Black stripe) (5) attaches to the low side service port. This service port is located on the A/C suction line behind the left shock tower.
