Manifold Gauge Set Connections

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not use an R-12 manifold gauge set on an R-134a system. The refrigerants are not compatible and system damage will result.

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 appropriate ENGINE ELECTRICAL DIAGNOSTICS article 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.
