Removal ("C" & "K" Series)

  1. Discharge A/C system, using approved recovery/recycling equipment. On models equipped with front A/C system only, remove front grille. Using a back-up wrench, loosen condenser-to-evaporator (liquid) line fitting at condenser and disconnect line.
  2. On models equipped with rear A/C system, loosen condenser-to-evaporator (liquid) line fitting between junction block and evaporator. If necessary, remove air cleaner assembly.
  3. On all models, remove and discard fitting "O" ring. Using Orifice Tube Remover/Installer (J-26549-E), remove orifice tube from liquid line. If difficulty is encountered during removal of a plugged or restricted orifice tube, remove as much residue as possible.
  4. Using a heat gun, carefully apply heat 1/4" from dimples on liquid line. DO NOT overheat line. If A/C pressure switch is located near orifice tube, remove switch to protect from heat.
  5. While heat is being applied, grip orifice tube using orifice tube remover/installer. Use a turning motion along with a push-pull motion to loosen and remove orifice tube.
