Lincoln Mark VII A/C Orifice Tube
The A/C Orifice Tube in the Lincoln Mark VII regulates liquid refrigerant through the air-conditioning system to cool the cabin. The A/C Orifice Tube controls high discharge and low suction through a fixed metering passage, causing the compressor to cycle to maintain system pressure and keep the cabin air cold. In contrast to an expansion valve that regulates through the movement of its parts, this simple device has no sensors, which means when debris plugs up the mesh screen, the evaporator may freeze or cooling may fade at idle. All Lincoln vehicles produced during the Mark VII run applied the same fixed-style A/C Orifice Tube. There are no spring-loaded or adjustable variants to compare otherwise. The built-in filter of the system traps dirt to safeguard other Lincoln climate components and keep gauge readings stable. When the tube is fouled, drivers see temperature swings at the lights or see erratic pressures, clear signs for any Mark VII owner to check the A/C Orifice Tube. In late-production Mark VII cars, the A/C Orifice Tube prevents strain on the compressor and ensures consistent summer comfort from your Lincoln cruiser.

Lincoln Mark VII A/C Orifice Tube Parts Questions & Experts Answers
- Q: How to replace the A/C Orifice Tube in the air conditioning systems on Lincoln Mark VII?A:This information applies only to air conditioning on 1980 through 1995 models, which use an accumulator/drier with a fixed orifice tube. Have the system discharged by a dealer service department or an automotive air conditioning repair facility. Disconnect the cable at the negative battery terminal. Disconnect the liquid line from the evaporator core at the accumulator/drier. Pour a small amount of refrigerant oil into the evaporator core tube to lubricate the O-rings seals on the orifice tube during removal. Using the special tool, engage the tool on the fixed orifice tube and remove it from the liquid refrigerant line. Caution: DON'T try to remove or install the fixed orifice tube with anything except the special tool. To try to remove any other way will break the fixed orifice tube inside the evaporator core tube, and may require the replacement of the evaporator core. Cap or plug the open refrigerant lines immediately to prevent any dirt or excessive moisture from entering the system. Lubricate the O-rings on the new fixed orifice tube with clean refrigerant oil. Place the new fixed orifice tube into the special tool (the same tool is used for removal and installation) and insert it into the evaporator core tube until the orifice tube is seated at the stop. Remove the tool. Replace the O-ring at the refrigerant line spring lock coupling. Reconnect the refrigerant lines. Have the system evacuated, recharged and leak tested by a dealer service department or an air conditioning repair facility.
