Have the refrigerant discharged and recycled by an air condition technician. Then, disconnect the ground cable from the negative terminal of the battery. Next, disconnect the refrigerant lines and remove the mounting bolts. On the Integra, the A/C Accumulator is located below the headlight on the driver's side. It's necessary to remove the lower splash pan on the driver's side for access. After that, remove the mounting bolts and lift the A/C Accumulator out of the vehicle. Installation is simply the reverse of removal. Finally, have the system evacuated, charged and leak tested by the shop that discharged it. If the accumulator was replaced, have them add 1/3 ounce of refrigeration oil.
