To remove the A/C accumulator from a vehicle's air conditioning system, first have the refrigerant discharged by a technician and disconnect the negative battery cable. Then, remove the bumper cover and use a hex bit or Allen wrench to unscrew the end plug and remove the A/C accumulator from the
A/C Condenser. To install, reverse the removal steps and ensure the end plug is tightened to the proper torque specifications. Have the system evacuated, charged, and leak tested by the shop that discharged it, and if the A/C accumulator was replaced, add the appropriate amount of refrigeration oil to the compressor using only oil compatible with the refrigerant.
