Ford Mustang (1999-2004) Service Manual: Refrigerant Lines
The condenser to evaporator tube (19835) contains the high pressure liquid refrigerant upstream of the evaporator core orifice.
The A/C manifold and tube (19D734) 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 also contains a fitting used to mount the refrigerant containment switch (3.8L) or dual-function pressure switch (4.6L). A long-travel Schrader-type valve stem core is installed in the fitting so that the switch can be removed without discharging the A/C system.
A/C Evaporator Core
NOTE: The evaporator core is not separately serviceable, it is serviced only with the evaporator core housing assembly.
NOTE: Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of contamination from a failed A/C compressor or damage to the suction accumulator.
The A/C evaporator core is the plate/fin type with a unique refrigerant flow path.
- A mixture of refrigerant and oil enters the bottom of the A/C evaporator core through the A/C evaporator core inlet tube and moves out of the A/C evaporator core through the A/C evaporator core outlet tube.
- This flow pattern accelerates the flow of refrigerant and oil through the A/C evaporator core.
A/C Compressor Pressure Relief Valve
An A/C compressor pressure relief valve is incorporated into the compressor
A/C manifold and tube to:
relieve unusually high refrigerant system discharge pressure buildups.

Engine Oil Leaks
NOTE: When diagnosing engine oil leaks, the source and location of
the leak must be positively
identified prior to repair.
Prior to carrying out this procedure, clean all sealing surface areas with a
suitable solvent to remove all
