it's in the high pressure liquid line.
A/C Evaporator Core Orifice
The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage).
The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation.
An orifice tube replacement service kit may be used as an optional service procedure.
Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.
-----------------------------------------------------------------------------------
A/C Evaporator Core Orifice Replacement Kit Installation
-
Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
-
Remove condenser to evaporator tube (19835) from vehicle.
-
Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.
A/C Evaporator Core Orifice Location
-
Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
-
Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.
A/C Evaporator Core Orifice Section Removed From the Liquid Line
-
Remove contaminants from the two pieces of the condenser to evaporator tube.
-
NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.
Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.
