Is the evaporator core separately serviceable, and what steps should be taken when repairing the refrigerant system on Mercury Grand Marquis?

The evaporator core requires replacement when it breaks because it exists as a single unit with the housing assembly. The suction accumulator remains replaceable only when physical contamination marks appear from a failed A/C compressor or complete suction accumulator destruction takes place. The evaporator core needs leak testing before its removal from the vehicle when there is suspicion of leakage. Start by taking out the evaporator core housing from the vehicle and move all parts from the old housing to the new housing unit before installation. The new evaporator core housing should be installed at the end of the process.
