Q: How to replace the accumulator in an air conditioning system on Mercury Capri?
A: To begin, discharge the air conditioning system and disconnect the negative battery cable. Then, unplug the electrical connector from the pressure switch and disconnect the refrigerant line from the accumulator, using a back-up wrench. Make sure to plug the open fittings to prevent dirt and moisture from entering. Loosen the holddown bracket pinch bolt and remove the accumulator. If installing a new accumulator, remove the Schrader valve and pour out the oil, noting the amount. Add fresh refrigerant oil to the new accumulator, equal to the amount removed from the old unit plus one ounce. Finally, reinstall the accumulator and take the vehicle to a shop for evacuation, charging, and leak testing of the air conditioning system.
Q: How to remove and install a receiver/drier on Mercury Capri?
A: A A/C Accumulator is used on 1979 through 1981 models. Have the air conditioning system discharged. Remove the radiator grille. Position the ambient cutoff switch out of the way. Disconnect the refrigerant lines from the A/C Accumulator. Remove the A/C Accumulator attaching screws and take it off the condenser. Installation is the reverse of removal. Take the vehicle back to the shop that discharged it. Have the air conditioning system evacuated, charged and leak tested.
