The accumulator/drier stores refrigerant and removes moisture in the air conditioning system. It should be replaced when a major component is changed or if exposed to air. To remove it, have the system discharged at a dealer or AC shop, disconnect the negative battery terminal, and disconnect the compressor clutch cycling switch. Disconnect the refrigerant lines, cap them, and remove the accumulator/drier. If replacing, drain the old refrigerant oil and add the same amount plus two ounces to the new one. Install the new accumulator/drier, reconnect the lines, and secure the clamp bolt. Reconnect the electrical connector and battery terminal. Finally, have a professional evacuate, recharge, and test the system.

To remove the accumulator/drier, you need to take the vehicle to a dealer service department or automotive air conditioning shop to have the system discharged. Then, disconnect the cable at the negative battery terminal. Next, disconnect the electrical connector at the compressor clutch cycling switch on top of the accumulator/drier. After that, disconnect the refrigerant inlet and outlet lines using the appropriate tools and cap or plug the open lines immediately. Finally, remove the nut from the mounting bracket and slide the accumulator/drier assembly out.
