Removal ("J" & "N" Body)

  1. Locate orifice tube. See ORIFICE TUBE LOCATION & REMOVER/INSTALLER APPLICATION (GENERAL MOTORS)  table. Discharge A/C system, using approved recovery/recycling equipment. On "J" body, remove upper closeout panel. On "N" body, raise and support vehicle. On all models, disconnect condenser-to-evaporator line at condenser outlet and discard "O" rings.
  2. Disconnect condenser-to-evaporator line clip on right-side body rail, behind engine mount. Remove as much impacted debris as possible. Grip orifice tube using needle-nose pliers. Using a turning and push-pull motion, remove orifice tube.
  3. If difficulty is encountered during removal of a plugged or restricted orifice tube, apply heat to orifice tube using a heat gun. Carefully apply heat 1/4" (7 mm) from dimples on condenser inlet line. DO NOT overheat line.
  4. If A/C pressure switch is located near orifice tube, remove switch to protect from heat. While heat is being applied, grip orifice tube using orifice tube remover/installer or needle-nose pliers. Use a turning motion along with a push-pull motion to loosen and remove orifice tube.
