Crown Victoria V8-4.6L VIN W (2000)
Hose/Line HVAC: Description and Operation
NOTE: Installation of a new suction accumulator/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 suction accumulator/drier.
The condenser to evaporator tube contains high pressure liquid refrigerant upstream of the A/C evaporator core orifice.
The A/C compressor to condenser discharge line contains high pressure refrigerant gas. It has the following features:
-
an integral non-serviceable muffler
-
a fitting used to mount the A/C pressure cut-off switch. (A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C
pressure cut-off switch can be removed without discharging the A/C system.)
-
a fitting used to mount a serviceable high-pressure A/C charge port valve
The A/C manifold and tube is attached to the A/C compressor 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 port to mount the A/C compressor pressure relief valve.
The accumulator to compressor tube has a fitting used to mount the A/C cycling switch. A long-travel Schrader-type valve stem core is installed in the
fitting so that the A/C cycling switch can be removed without discharging the A/C system.
