Q: How to replace a compressor in a Lincoln Town Car's air conditioning system?
A: Whenever a compressor is replaced, it is necessary to replace the accumulator/drier or the receiver/drier with fixed orifice, depending on the system the vehicle is equipped with. To begin the removal process, the accessory drivebelt(s) must be removed. The system should then be discharged by a dealer service department or an automotive air conditioning repair facility. The refrigerant lines are then disconnected from the compressor, along with the electrical connection at the compressor clutch. The compressor mounting bolts are removed, and the compressor is taken out of its mounting location. The refrigerant oil from the compressor should be drained and measured. For installation, if the compressor is being replaced, the appropriate amount of refrigerant oil should be added to maintain the correct level. The installation procedures are the reverse of those for removal, and if connections were disassembled that use O-ring seals, new O-rings should be used and lubricated with clean refrigerant oil upon reassembly. Finally, after the compressor is installed, the system should be evacuated, recharged, and leak tested by a dealer service department or an air conditioning repair facility.
