  Description and Operation  
 

  

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

The A/C evaporator core orifice has the following characteristics:

  • it is located in the rear condenser to evaporator tube.
  • 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 A/C evaporator core orifice.
  • O-ring seals on the A/C evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the A/C evaporator core orifice.
  • Adjustment or repair cannot be made to the A/C evaporator core orifice assembly. It must be serviced as a unit.
