Have the refrigerant discharged by an air conditioning technician. Disconnect the negative battery cable. Using an Allen wrench, detach the end plug and remove the A/C Accumulator from the condenser with a pair of needle-nose pliers. If the end plug is not accessible with the air conditioning condenser installed, the condenser may have to be removed. Use new O-rings when installing the new A/C Accumulator and tighten the end plug to the specified torque, ensuring to lubricate the O-rings with R-134a compatible refrigerant oil. Installation is the reverse of removal. Have the system evacuated, charged, and leak tested by the shop that discharged it.
