Some models have a traditional A/C accumulator, which is mounted at the right front of the engine compartment. Models that do not have a separate A/C accumulator have one that is built into the side of the condenser. First, have the refrigerant discharged by an air conditioning technician. Then, disconnect the negative battery cable. If the A/C accumulator is integral with the condenser, use an Allen wrench to detach the end plug and remove the accumulator from the condenser with a pair of needle-nose pliers. Use new O-rings when installing the new accumulator and tighten the end plug. Be sure to lubricate the O-rings with R-134a compatible refrigerant oil. Installation is the reverse of removal. If the A/C accumulator is separate, disconnect the refrigerant lines from the A/C accumulator and cap the open fittings to prevent the entry of moisture. Unscrew the two mounting bolts and remove the A/C accumulator. Loosen the clamp bolt and slide the A/C accumulator out of the bracket. Install the new A/C accumulator by reversing the removal procedure. If a new A/C accumulator is being installed, add 20cc (0.71 ounce) of R-134a compatible refrigerant oil to it before connecting the lines. Be sure to install new O-rings on the refrigerant lines, and lubricate them with R-134a compatible refrigerant oil, before connecting the lines. Finally, have the system evacuated, charged, and leak tested by the shop that discharged it.
