First step will be having the refrigerant emptied and retrieved by a certified repair institute. In 1990-1994 models, take off the radiator grille whereas in 1995 -plus, remove the splash shield of the driver side and fender mud guard. In 1995 and subsequent models, also detach the
Coolant Reservoir, fresh air duct, air cleaner and resonance chamber (where applicable), wring disconnect the A/C Accumulator pressure switch electrical connector. In all models, after emptying the system, disconnect the refrigerant lines to the A/C Accumulator by removing the refrigerant line clamp bolt and once the lines are disconnected, one should cover the open lines with a cap to avoid entry of moisture. The next step is to remove the A/C Accumulator mounting bolts and the A/C Accumulator. Installation is done in reverse sequence of removal i.e. any O-ring that is broken should be replaced with a new O-ring which is in accordance with the type of refrigerant in the system and lubricated with refrigerant oil before being installed. Lastly, evacuate, charge and test the system leaks by the same shop that emptied it and in case the A/C Accumulator was changed, add new refrigerant oil to the high pressure side of the compressor, but only with oil that is compatible with the system.
