Ford Mustang (1999-2004) Service Manual: Evaporator Core Orifice

Evaporator Core Orifice

NOTE: The evaporator core orifice is an integral part of the condenser to evaporator line and should be installed as an assembly with the line.

NOTE: A new evaporator core orifice should be installed whenever a new A/C compressor is installed.

The evaporator core orifice has the following characteristics:

  • It is located in the A/C condenser to evaporator line.
  • It has filter screens located on the inlet and outlet ends of the tube body.
  • The inlet filter screen acts as a strainer for the liquid refrigerant flowing through the evaporator core orifice.
  • O-ring seals on the evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the evaporator core orifice.
  • Adjustment or repair cannot be made to the evaporator core orifice assembly. A new evaporator core orifice must be installed as a unit.
    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, ...
