Continental V8-4.6L DOHC VIN V (1998)
Hose/Line HVAC: Description and Operation
NOTE: Whenever the refrigerant line is replaced, it is also necessary to replace the suction accumulator/drier.
The aft condenser to evaporator tube contains the A/C evaporator core orifice. When the A/C system is in operation:
^
There is high pressure liquid refrigerant upstream of the A/C evaporator core orifice.
^
There is low pressure liquid refrigerant downstream of the A/C evaporator core orifice.
The forward condenser to evaporator tube is equipped with a serviceable high pressure A/C charge valve port.
The evaporator to accumulator/drier suction line contains low pressure refrigerant gas and is equipped with a serviceable low pressure A/C charge valve
port.
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 and an integral non-serviceable muffler.
^
The downstream side contains high pressure refrigerant gas and an integral non-repairable muffler.
^
The downstream side also contains a repairable A/C compressor pressure relief valve and a fitting used to mount the A/C pressure transducer. A
long-travel Schrader-type valve stem core is installed in the fitting so that the A/C pressure transducer can be removed without discharging the A/C
system.
