Expansion Block/Orifice Tube: Description and Operation
NOTE: The A/C evaporator core orifice should be replaced whenever an A/C compressor is replaced.
The A/C evaporator core orifice has the following characteristics:
^
Color-coded orange.
^
Has an orifice diameter of 1.45 mm (0.057 inch).
^
Is located in the aft condenser to evaporator tube.
^
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 A/C evaporator core orifice.
^
O-rings on the A/C evaporator core orifice prevent the high-pressure liquid refrigerant from by-passing the A/C evaporator core orifice.
^
Adjustment or repair cannot be made to the A/C evaporator core orifice assembly. It must be replaced as a unit. This requires replacement of the
condenser to evaporator tube or installation of the Evaporator Core Orifice Replacement Kit.
