How to remove and install an air conditioning system's accumulator?

To remove the accumulator, you must discharge the system. The refrigerant inlet and outlet lines should be detached and capped to prevent debris from entering. To install a new accumulator, fresh refrigerant oil must be added to the unit. The new accumulator should be placed in the bracket and installed onto the bulkhead. It is also important to finish off by evacuating, recharging, and leak test.
