How to replace the A/C Orifice Tube in the air conditioning system on Lincoln Town Car?

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.

Lincoln Town Car A/C Orifice Tube

The A/C Orifice Tube of the Lincoln Town Car connects the high-pressure and low-pressure sides of the system, keeping the cabin cool. The fixed bore in the A/C Orifice Tube meters the refrigerant at a constant flow rate. This helps the compressor cycle on and off to maintain pressure and stop evaporator freeze. The A/C Orifice Tube is designed for long-running Lincoln sedans since it has no moving parts, unlike the adjustable expansion valve. Throughout each generation of the Town Car, this single straight-through style ensured step consistency. The A/C Orifice Tube filters debris that could obstruct narrow paths as refrigerant flows through. Cleaning or replacement is required if you notice that clogging is bringing in cool air when cruising, but weak output when idling, bizarre pressure readings, or ice on the evaporator. Prompt servicing prevents heat-exchange loss and helps the Lincoln Town Car compressor be more effective. A clean A/C Orifice Tube safeguards lasting comfort for every Lincoln Town Car on the road.

We provide a wide range of Lincoln Town Car A/C Orifice Tube at the optimal prices. If you need Lincoln Town Car A/C Orifice Tube, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your doorstep with a fast delivery service.
