  Q: How to replace the A/C Accumulator on Mazda MX-5 Miata?

  A:

  For models from 2000 and earlier, the A/C Accumulator is located at the right end of the condenser. Begin by having the refrigerant discharged and recovered by a qualified repair facility. Disconnect the battery negative cable, block the rear wheels to prevent rolling, jack up the front end, and secure it on jackstands. Remove the splash shield and air guide panels from under the front of the vehicle. Disconnect the refrigerant lines from the A/C Accumulator, capping the open fittings immediately to prevent moisture entry. For 1997 and earlier models, remove the bolt from the A/C Accumulator clamping band and take out the A/C Accumulator. For 1999 and 2000 models, remove the two nuts securing the A/C Accumulator to the mounting bracket on the condenser. For models from 2001 through 2005, the A/C Accumulator is an integral component of the condenser, and if it needs replacement, the condenser must also be replaced, although a separate A/C Accumulator may be available in the aftermarket. For models from 2006 and later, have the air conditioning system refrigerant discharged and recovered by a qualified repair facility, raise the front of the vehicle and secure it on jackstands, remove the engine compartment under cover, and take out the flange bolt securing the inlet and outlet refrigerant lines to the A/C Accumulator. Remove the mounting bracket bolt and take out the A/C Accumulator from the condenser. Discard the old refrigerant line O-rings and always use new ones when reattaching the refrigerant line flange to the A/C Accumulator. Installation is the reverse of removal, ensuring to replace any O-rings with new ones made for the refrigerant type in your system and lubricate them with refrigerant oil before installation. Finally, have the system evacuated, charged, and leak tested by the facility that discharged it, and if the A/C Accumulator was replaced, ensure they add new refrigerant oil to the high-pressure side of the compressor, using only oil compatible with your system.
