Aviator 2WD V8-4.6L DOHC (2003)
Hose/Line HVAC: Description and Operation
REFRIGERANT LINES
NOTE: Installation of a new receiver/drier is not required when repairing the air conditioning system except when there is physical evidence of system
contamination from a failed A/C compressor or damage to the receiver/drier.
The compressor manifold and tube assembly is attached to the A/C compressor, is sealed with O-ring seals, and has the following features:
-
The upstream side contains low pressure refrigerant gas.
-
The downstream side contains high pressure refrigerant gas and a fitting used to mount a serviceable high-pressure A/C charge port valve. The
downstream side contains a fitting used to mount the refrigerant containment switch. A long-travel Sebrader-type valve stem core is installed in the
fitting so that the refrigerant containment switch can be removed without discharging the A/C system.
-
The downstream side also contains a pressure relief valve.
